Transmission problem.. No reverse, but all forward gears work. I wanted to replace the ATP Module, but I can not locate it. I have a T transmission in my 93 Old Cutlass Supreme S.

    Actually , I have a 1993 2-Door Cutlass Supreme and just yesterday the overdrive stopped working. I shifted into 3rd gear and then back into OD and there was no change in RPM, so I think that OD is just burnt. No check engine light.

    All other gears are operational at this time.

The transmissions in these cars (4T60E) were NIGHTMARES!!!!!! Do yourself a favor to avoid continuous problems. Replace it with a trusted transmission dealer> I can't say who not to take it to but it rymes with slamco (haha)
other problems that will occur, even if you replace the ATP
1. in winter time when you shift to drive it hesitates or feels like it is only partially in gear (fluid will be full when you check it)
2. car shudders in overdrive.
3. car makes a destinct "klunking" noise while in park at a slightly higher RPM. almost sounds like something is loose in the motor.
so like i said get it replaced, I have been though 3 of these since my car was new the car has 263K on it now and i am about to replace it again (argh). The only reason I am is because it is a convertible in nearly mint shape,,
OH by the way "Trans X" is a GREAT product to prolong the replacement adventure. Local auto parts stores have it by that name.

Both error codes you have are transmission related. P0736 is an error for reverse has wrong gear ratio. P0700 is a general transmission problem code

Jetta no reverse

There's really nothing in the linkage that would go that would not interfere with the forward gears. It sounds like you have fine fluid pressure in the transmission if the forward gears work ok, but the loss of reverse sounds like either a solenoid in the valve body is not working (which may set a fault in the transmission control module) or that something is blocking the fluid flow (some of the channels in the valve body are tiny and it would only take a grain of debris)
I would say that your first step would be to have the modules scanned. This is the least expensive and least intrusive procedure.
After that you may want to have them drop the transmission pan and inspect and see of there is excessive debris in the pan, indicating the failure of one of the clutch packs or other internal wear- It's usually OK to see fine "glitter" in the pan, but NOT OK to see "metal flake" or any chunks. If everything looks good, it may be worth it to try changing the fluid completely and seeing if that solved the problem- it takes more pressure to activate reverse than the other gears, so if your fluid is low it won't build enough pressure.
If none of the above work, then the problem is likely farther internal- it could be the valve body, but that's an expensive part to "test" since you can't replace it, and it's usually more feasible at that point to simply go all the way and replace the transmission.

Automatic transmission will not engage gear

Sounds like the transmission is gone .Check the fluid level ,and sometimes the filters inside the transmission gets clogged up.have it checked by a qualified transmission mechanic.

V70 poured new Dex3 auto trans in. Reverse gear stops working after a few days equal 500km, but all forward are still ok.

Sounds like your transmission is going bad. If your transmission is slipping only in drive or forward gears, then it could be just that it is low on fluid, but when reverse starts to slip it usually means rebuild/replace transmission.

Good luck

95 mustang v6 auto no forward gears but works in reverse had ****** rebuilt and same thing

Maybe your differential is shot and will only allow reverse spin or the transmission was not really rebuilt professionally. Was the transmission checked outside of your car after rebuild? Does your vehicle have a Powertrain Control Module (PCM)? Maybe the module went bad or faulty.

Transmission goes forward in reverse,neutral,actuall in all gears except park tranmission control solenoid has been changed

You have a serious mechanical failure in the transmission, it will need to be rebuilt or replaced.

Forward gears working, no reverse

Make sure to check your transmission fluid levels first and make sure there is no leak in the transmission lines.

Manual transmission won't shift into reverse

Your reverse gear is worn down, unfortunately, you will have to get your reverse gear replaced, if the forward gears are working properly. if not, a new transmission (or rebuilt) will be necessary.

E4OD Trans stays in OD no matter where the shifter position is.

Transmission Description The E4OD transmission is a fully automatic, electronically controlled, four-speed unit with a torque converter clutch. The main operating components of the E4OD transmission include a torque converter clutch, six multiple-disc friction clutches, one band, one sprag one-way clutch and two roller one-way clutches that provide for the desired function of three planetary gear sets. Transmission gear selection in the (D) range and converter clutch operation is controlled by the powertrain control module (PCM) (12A650). Operating conditions are relayed to powertrain control module by various sensors throughout the vehicle. The powertrain control module compares these conditions with electronically stored parameters and logically determines how the transmission should operate. A torque converter (7902) couples the engine to the transmission gearset via the input shaft (7017) and the torque converter impeller hub. The impeller hub provides engine rpm to the positive displacement pump. The flow from the pump is proportional to engine rpm, and excess pump capacity is exhausted back to the pump inlet. The input shaft transfers power into the transmission gearset. The power input is controlled by the application of the torque converter clutch, which is scheduled through the powertrain control module. The application of the piston plate effectively replaces the hydraulic coupling between the converter cover and the turbine with a mechanical coupling between the converter cover and the turbine hub. This mechanical coupling helps improve fuel economy and wide-open throttle performance by eliminating converter slip. Transmission shift selection and torque converter clutch operation are controlled by the PCM. They are calibrated to provide the optimal transmission state. This state is commanded to the transmission solenoid body. In the (D) range, automatic operation of all four gears is possible. The transmission control switch, located on the vehicle's shift lever disables overdrive operation and enables automatic operation through the first three gears. Whenever the ignition switch is turned on, the vehicle will automatically provide overdrive operation regardless of the switch position the last time the vehicle was running. Manual gear selection is available in the 1 and 2 range. Second gear is commanded when the gearshift selector lever is in the 2 range and when downshifted into the 1 range at speeds above approximately 56 km/h (35 mph) (for diesel 48 km/h [30 mph]). First gear is commanded in the 1 range at start-ups and when downshifted into 1 range below approximately 56 km/h (35 mph) (for diesel 48 km/h [30 mph]). Any reference to intermediate brake drum or direct clutch cylinder are one and the same.
I think this is your problem:

Programmable Speedometer/Odometer Module (PSOM): Description: The programmable speedometer/odometer module receives input from the rear brake anti-lock sensor, which is mounted on the rear axle differential housing. The PSOM processes this input signal information and relays it to the powertrain control module and the speed control module. This signal tells the powertrain control module the vehicle speed in miles per hour (mph). Used as an input in determining shift scheduling and electronic pressure control. Symptoms: Harsh engagements, firm shift feel, abnormal shift schedule, unexpected downshifts may occur at closed throttle, abnormal torque converter clutch operation or engages only at wide-open throttle (WOT). May flash transmission control indicator lamp. Diagnostic Trouble Codes: 452, P0500, P1500, P1501, P0503
