Car is not holding gear, keeps slipping out and feels like its pulling in about 2nd gear. Its a 1999 chrysler voyager automatic.

Pull the trans & rebuild it

Can't fix slipping

You hit the nail on the head Gaz, But you need to hook it up to a scanner to see which one is defective.

sounds like a problem in the PCM. a more sophisticated diagnostic computer is needed to test the system out, most repair shops should have these. i would get multiple estimates from different garages and one from a dodge dealer.

The geabox fluid needs changing, if the gear changes seem jerky changing up and down, the gearbox needs to be refurbished.

Sounds like you need a solenoid pack to start, and possibly a service. If the tranny is not slipping, the solenoid pack is stuck and not tell it to shift up. Could possibly be a TCM, but not as likely.

I had the same problem in my 1999 plymouth voyager. Changed both speed sensors it started shifting perfectly.. Now i get a little thump when downshifting from 2nd to first when stoping change the sensors there only about 20 dollars each its 2 of them on the front of transmission..

If the fluid is full , it sounds like the trans pump is loosing prime. If it is there will be a code set. The code will not always turn on the light. Go have the codes checked. If it does have a loss of prime code in the trans computor and the fluid is full then you will need the trans pump replaced

sounds like it is in limp mode, this is the trans way of preventing further damage. You need to take it to trans shop for diagnostic

will need new clutch
