4r70w 1st gear problem

Also, did you use seal protectors to install the pistons? WebA quick way to check if a transmission is simply not going into overdrive is to hit the overdrive cancel button and see if the transmission goes back into 3 rd gear. The spring is compressed to make way for the C-clip retainer. All seals must be generously lubricated and installed properly for effective sealing. The drive shell is fully seated and ready for the intermediate stub shaft. The vehicle in question was a 2014 Ford Econoline E-250 bus. Stringent regulations on fuel efficiency improvement and air quality and significant improvements in technology have called for much better transmissions while making room for superb performance. And for this to happen successfully, the manufacturers had to sacrifice a handful of the speed and performance features that older models exhibited. This cookie is set by GDPR Cookie Consent plugin. Is the torque converter doing its job? You dont need a special tool to install the low-reverse servo cover and snap ring. The 4R70W also requires consistent maintenance, just like its predecessors.This way, you will have an incredibly powerful transmission. Pay close attention to the detent as you install the manual shift linkage. If you get a harsh 2-3 upshift, the problem is likely the 2-3 accumulator or excessive line pressure. But then, the 4R70W is also not a great place to end your search either. Contact Us - There should be nine springs in serviceable condition free of distortion. As a result, Ford engineers added a spring to give the 3-4 shift valve a helping hand. The cookies is used to store the user consent for the cookies in the category "Necessary". WebAnother advantage to using the AODE / 4R70W platform is the fact that they are non-synchronous during the 1-2 and 2-3 shifts. Servo apply pressure is controlled by the low servo modulator valve. Legal/Privacy. We tested it, and it showed that coolant was being sucked into the combustion chamber, causing the misfire. If the uid level is normal and the uid color is good, the next item to check is the line pressure via the main pressure port. So the valve body on 4r70w and maybe 4r75w tend to wear out so replacing the whole valve body is recommend instead of trying to fix the valve bores in my opinion you are eliminating further issues, valve body on eBay good with one year warranty 65$ bucks thats super cheap fix for these mysteriously instantaneous loss of forward gears without If the seal lip is pointed away from the bore, it does not hold pressure and the servo piston does not function. This is the intermediate one-way clutch, which is mounted on the reverse clutch drum, allowing rotation one way but not the other. All of these items are checked by dropping the valve body and visually inspecting them. This drain hole must be at 6 oclock. The MCCC is off (on the torque converter, no lockup). Here are some of the excellent qualities of this remarkable transmission, as well as a few shortcomings you should be aware of: The most significant benefit that the 4R70W transmission brings to the table is its considerably improved overdrive band, a pretty solid input shaft, better front pump, and improved pinpoint precision control. Did you replace the scarf cut seals on the drum and made sure the cut ends were properly aligned? The 2-3 shift-point is also raised by a factor of 5.4 percent to produce a full-throttle 2-3 shift at about 4,750 rpm. Install the forward clutch piston seals. Install the low-reverse band servo piston return spring. Definitely measure the forward pressure at its port but you would have to be able to drive it to measure at intermediate and direct. The difference is the SS1 function. Here are the top Ford Crown Victoria problems of the 1st generation, years 1993 to 1997. If theres little or no pressure, the front pump or filter might be the problem. Pressure is instead directed to the overdrive servo regulator valve. If your AODE/4R70W experiences no 3-4 upshift, it is a sticking 3-4 shift valve, overdrive servo issue, or a failed overdrive band. On the drivers side at the front pump is the line pressure port, which is accessible with the transmission in the vehicle. Check this ring carefully for proper seating. Apply transmission assembly lube on all contact surfaces. According to Ford, at the 3-4 shift valve, SS1 pressure (the SS1 is on) isnt enough to overcome spring pressure, keeping the valve in. A switch to the wide-ratio gearset increases the 1-2 shift-point by 18.3 percent (multiply 4,800 rpm by 1.183 to obtain a new shift-point of about 5,680 rpm). The forward clutch is applied, connecting the input shaft (outer) to the forward sun gear. The truth is there is no perfect stock transmission. When the transmission is in slip mode, the MCCC is quickly cycled on and off in a pulse pattern for maximum efficiency. Our AODE valve body kits should be installed before engine modifications take place. If Fords AOD evolved into a highly successful mechanically modulated transmission from its 1980 introduction until production ended in 1991. Subscribe. All Rights Reserved. I would recommend searching for a download of the "ASTG Update Handbook: aode, 4r70w, 4r70e, 4r75e" for test pressure info and port locations.

If this cannot be achieved, go with the appropriate retaining ring: .060 to .064, .074 to .078, .088 to .092, or .102 to .106 inch. The uid condition is your first indication of transmission health. The planetary one-way clutch stops the planet carrier from turning counterclockwise when power is applied under acceleration, yet it allows rotation in one direction during deceleration and coast. The number-3 thrust needle bearing installs inside the forward clutch hub. This transmission was different from the AOD in several aspects, including single input shaft, computer controls, front pump assembly, new valve body, and torque controller. The only inter-changeable components are geartrain related. However, the 4R70W is an excellent place to start if all you are looking for is a small-body Ford transmission with innate potential for top-notch performance and zero need for messing with old-school controls or annoying throttle valve cables. TIPM Problems! Not enough line pressure and you get slippage. Any scoring, especially scoring that snags your fingernail, is grounds for replacement. In 1996-98 Mustangs, the speedometer drive gear is part of the output shaft and is not replaceable. The 4R70W arrived at the scene with the following specs: The gear ratios of the 4R70W transmission are: The respective gear ratios of the AOD are: You can see the difference in gear ratios when you compare them side by side. Bucko133. In first gear in the drive range, the SS1 is on and the SS2 is off. If it is brown or otherwise dark in color that is a clue. Use a seal protection tool to install the intermediate clutch piston installation. Do not take shortcuts. The AOD efficiently replaced several older transmissions that Ford put out, including the C4, C5, and FMX. When you build, use new Torringtons if possible. Attachment bolts receive 80 to 100 in-lbs (not ft-lbs). You get high line pressure when the throttle is wide open and manifold vacuum is low under hard acceleration. In second gear in drive range, both the SS1 and SS2 are off. Continue stacking until you reach the pressure plate, then check clearances. Terms of Service - This requires careful twisting and turning until the clutches and hub fully mate. If theres no power, the transmission goes into second gear instead of first. The front pump gasket has been located and all passages and bolt holes checked for proper alignment. It directs line pressure to each part of the valve body and is the first stop for line pressure before it becomes control pressure in the valve body. The number-5 needle bearing is already installed here. Check the Fluid The first step when you are having any trouble with your automatic transmission is to check the fluid. Troubleshooting the AODE/ 4R70W begins with ascertaining the problem. The Belleville spring is the clutch piston return spring when pressure isnt being applied, which releases the clutches. Privacy Statement - Precision-machined aluminum spool valves provide weight reduction and a more precise fit. Ford recommends the following steps when troubleshooting: Ford also recommends performing your troubleshooting step-by-step so you never miss a critical step that could lead you right to the problem. Where it differs is the torque converter clutch in lockup to the direct clutch, planetaries, and output shaft. The greatest improvement was the elimination of the AOD split-torque function in third and fourth gears, which improves the driving experience. According to ASTG all your line pressures are fine. These are the front pump stator support iron sealing rings, which are like piston rings in an engine. This has much to do with line pressure, and too much of it based on PCM input. The uid color should be reddish-pink. It wasnt all that different from the FMX 3-speed automatics since common FMX components such as the Ravigneaux gear train, etc. The planets one-way clutch overruns. Twist and wiggle the stub shaft and feel for proper seating. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies.

Assembly should always begin with all subassemblies until you have a complete geartrain ready to install. Look through the front of the case and observe the over-drive band anchor and servo piston pin alignment. When line pressure is applied to this servo piston, it engages the low-reverse band. The extension housing received a new bushing. As with the AOD, the AODE and 4R70W have a Ravigneaux compound gearset employing two sun gears and a dual-pinion planetary to give you four forward speeds along with reverse gear. Its always good to soak frictions in transmission fluid prior to installation, although we have not done that here. Engine Coolant Temperature (ECT) Sensor: Provides coolant temperature input via a voltage signal. It could also be a misfire. Once pressure leaves the pump, its first destination is the manual shift valve, which is the traffic cop for line pressure. S1. Air pressure should be applied to serve as a valve function check. Cookie Policy - So i thought nothing of it and put the new ones back in and also installed a Transgo Shift Kit while I was there so I knew nothing was wrong with the valve body. Re: 4R70W tcc lock up in 1st gear. This TCI Automotive transmission overhaul kit has just about everything needed to complete an AODE/4R70W rebuild. Once you have the converter seated it is This roller clutch allows drum rotation in one direction only, like a ratchet. Check the pressure plate for freedom of movement in the clutch drum. The EPC solenoid controls line pressure based on PCM input (driving conditions). Make sure the C-clip is secure before moving on. When we dropped the pan it was full of metal, as expected. 178 subscribers. Lay the clutch discs and plates into the reverse clutch drum. Closely inspect all hard parts for scoring and cracking. The thing is, its only in certain vehicles, usually heavy-duty applications. It may also remotely be a The forward drum as far as I can tell looks to be in perfect shape. Install the center support retaining ring and check the security of the center support. The planetary one-way clutch overruns. After you add liberal lubrication to the output shaft seal, press it in. Does the engine stall when the transmission selector is placed in gear? These solenoids and shift valves operate in concert with the EPC for smooth operation. Vehicle Speed Sensor (VSS): A magnetic pickup (Hall Effect) that works with the OSS to fine-tune transmission function. Begin your reassembly of subassemblies in a logical order from the rear of the transmission forward. You can copy and paste this link to share: https://www.diyford.com/ford-aode4r70w-guide-calibration-building-troubleshooting/. The shift solenoids open the shift valves when they receive power. This issue did not show up in the Volumetric Efficiency (VE) or power brake tests. Alternate the forward clutch plates with clutch friction discs. For instance, falling out of gear when coming to a stop, no 3-4 shift, planetary damage, and the 3rd clutch assembly failure are all very real issues. Examine the check ball valves for freedom of movement. Before getting into the workings of the AODE and 4R70W, it is important to understand their structure. You may also use the Ford tool (PN T92P-70023-A). Rollers become pitted, and this isnt always visible. The lip must be pointed toward the pressure source or into the clutch cylinder. The top clutch plate should be your plate. Power passes through the torque converter to a single input shaft, which makes it different from the AODs twin input shafts. Ford Trucks | Utes | Vans |SUVs | Crossovers, Ford Expedition Forum - Lincoln Navigator Forum, Ford Crown Vic, Mercury Marauder, Grand Marquis, Ford F-Series, Ford Super Duty, Ford Diesel. 1st Gear: 2.84; 2nd Gear: 1.55; 3rd Gear: 1.00; 4th Gear: 0.70; Reverse: 2.23 This keeps the transmission in first gear. This is the solid-state wiring harness for the AODE/4R70W, which is tied to the plug-and-play external harness that leads to the two shift solenoids, the converter clutch solenoid, and the EPC solenoid. You also have the option to opt-out of these cookies. Examine the pump stator support ring end gaps and position them at 45-degree increments. I shifted down into 1st and it won't move, feels like it's in neutral. You also want to service the torque converter (not shown) with 2 quarts of transmission fluid, which helps prime the pump. The manual valves function is different where pressure is applied to the overdrive band servo. Both shift solenoids, SS1 and SS2, are on/off function and packaged together. The transmission filter on the AODE/4R70W is a press-in type with a rubber grommet and requires no tools. The 4R70W, a Ford transmission, is an evolution to the popular AODE and is often used interchangeably. Should either or both of these speed sensors fail, you may notice one or more of the following 3 issues: 1. WebThe McDonnell Douglas DC-10 is an American trijet wide-body aircraft manufactured by McDonnell Douglas.The DC-10 was intended to succeed the DC-8 for long-range flights. Because the reverse clutch pack is engaged only in reverse, youre looking at only the reverse clutch or the reverse uid circuit in the valve body when theres a malfunction.

Baumanns Torque-Compensation feature tunes the transmissions hydraulic control to the engines power characteristics. The converter clutch control solenoid is then controlled by the PCM. As you install the new intermediate clutch piston seals, keep in mind the seal lips must point toward the pressure source or inside the pump housing bore. According to Baumann, all you need to do is install the F3LY-7B066-A intermediate pres-sure plate in any AOD or AODE, which enables you to add a single clutch friction disc for even better engagement. Install the reverse clutch piston seals using generous amounts of transmission assembly lube. Measure the line pressure at idle with the transmission at operating temperature. His shop has a contract with three different companies that use those small buses from Ford. For a better experience, please enable JavaScript in your browser before proceeding. Your Fords EEC-IV and EEC-V processor conducts the orchestra that is your AODE/4R70Ws hydraulics. It does affect clearances. Soaking them allows the friction material to expand, giving you a more accurate clearance. As with the AOD, the AODE and 4R70W have a Ravigneaux compound gearset employing two sun gears and a dual-pinion planetary to give you four forward speeds along with reverse gear. There are two bands, two one-way clutches, and four friction clutches used to lock and drive the gearsets. Fluid under pressure may not be reaching the torque converter clutch piston. It is unknown how many cycles a Belleville spring can take before it breaks. Email: [emailprotected] Lots of metal at the magnet means hard part wear and tear, which calls for close inspection of the bushings, shafts, gearset, and more. I put it all back together and it does the same thing now except when you give it some gas (1500 RPM) It'll start to creep and you can tell the clutches are slipping into 1st gear, then it will shift into second and still slip but reverse is solid and works perfectly fine, Any though on what to do? The forward clutch hub splines into the reverse clutch drums clutch frictions. Torque the extension housing bolts to 16 to 20 ft-lbs. As mentioned earlier, no stock transmission is perfect in every aspect. Use plenty of lubrication, then drive the seal in. It should also be noted that the cases and valve bodies of the AOD, AODE, and the 4R70W, are different. Also install the input shaft sealing rings at this time.

About Us - Once this ring is seated, check its security. It also means theres no pressure to the intermediate clutch pack. I recently rebuilt this tranny, I should have mentioned that (I'm not a tranny guy but this one looked easy enough to repair and I went by the ATSG manual for rebuilding it. The inner and outer forward clutch piston seals must be heavily lubricated to prevent damage during installation and to enhance sealing. This cookie is set by GDPR Cookie Consent plugin. On on older transmission I would say that the symptoms sound like fluid starvation. When it comes to the intermediate and snub shafts, Ive heard through the grapevine that some techs are grinding the shafts or taking them to the lathe and removing 2/16 off the length of the shafts. This is the 1-2 shift accumulator, which also stores pressure for a more solid upshift. The bolt torque is 62 to 88 in-lbs. If you liked this article you will LOVE the full book. Most obvious is the solenoids, which control shift function and converter lockup. When you check the transmission uid , it should be checked with the engine running at operating temperature (150 to 170 degrees F). Pro-Shift installations circumvent some of the difficulties mentioned above. Privacy Policy. I would start by removing the valve body and inspecing it first. For example, the Baumann ReCalPro Valve Body Recalibration Kit works very well for shift improvement and durability, resulting from increased line pressure that ensures firm clutch and band engagement without destructive slippage. Work the sun gear drive shell back and forth to seat. Do not get this backward. Shop Finder And finally, torque converter clutch function can be full on, full off, or a smooth engagement, which is controlled by the MCCC. Erratic shifting One of the first symptoms of a bad or failing downshift solenoid is erratic shifting. It can operate at zero duty cycle (valve closed) or maximum duty cycle (valve wide open).
