SOURCE: while driving truck makes a humming sound in drive now no reverse

If you have no reverse then yes it needs to be rebuilt. as far as the whining it could be in one of the differentials. or in trans? just depends on where you hear it

SOURCE: 1994 Toyota Camry automatic. All forward no reverse

are you sure it is first gear it is making when in 1. In park does the car lock up if you try to push it with the handbrake off. If not your problem is adjustment of the cable i.e. although the lever is in reverse the gearbox isn't.

SOURCE: 1996 nissan no reverse or neutral

Unfortunately the only thing to do in this case is to open the gearbox and see the real status of the cylinders, it's very possible the cylinders do not make contact anymore.

Sounds like the lockup torque converter has failed. Repair requires trans removal and possible rebuild if converter has contaminated unit. Have a trans shop verify!!

SOURCE: 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

I have all gears but reverse and when in park and neutral and gas pedal is pressed the car moves forward, why?

well could be two things. either your transmission has crapped out on you. or you have a shifter linkage issue. which means when the car is in park its not really in park. try this. move the shifter and see if the car moves in a different gear then what it says it is in . so if it moves in neutral it could be drive and reverse is neutral. if it does not reverse at all. time for a new trany is my guess.

2000 ford explorer 5r55E stuck in second gear and all gear positions

It sounds like the linkages have let go. If this is the case, then drive it to a repairer straight away. If you turn the vehicle off you might not get it started again.

What engine? Rear wheel drive ?Sounds like shift linkage or cable out of adjustment slightly. Have a look at where cable or rod attaches to transmission for adjustment. If not sure of what your looking for get back to me with info.

1993 chevy blazer S10

That is a very common problem with General Motors 700R4 transmission. There is a shell that encases the majority of the forward gears and the reverse drum is on top of it and that completely encases the forward drum. at the bottom of that shell there is a collar that is about one quarter of an inch long that rides on a gear set called planetarys. those have a problem with breaking and cause no reverse and driving in neutral. that is the link between the front and rear shaft of the transmission and the weak link. for that to be repaired it has to be removed from the truck and taken apart. It is highly recommended that it be completly rebuilt not just patched due to all of the metal that is sent through the transmission.
