Sam,

I would start with a transmission fliud and filter service.

I would then have the trasnmission checked out by a transmission shop. The transmission most of the time has the direct drum band is starting to go. The shops can rebuild it no problem, This is a very common failure wiith the trasnmission.

Good Luck

The brake rlease switch for the gearshift might need adjusted-replaced or the shifter itself might need adjusted

I had a similar problem with a Dodge Caravan - On the Dodge, it's called limp mode, designed to protect the engine and tranny. If you can get the OBD-2 engine codes and look them up online you may find that the problem is elsewhere in the drivetrain. Not really an answer, but a solid suggestion of where to go from here....

I had same problem like your. Into 3 from 2 gear was rpm fly and gas take off for short time and it finally change 3rd then gas fine work and fine change into 4 gears. I also not want run 30 miles into town cuz worry broke down and more cost towing. Friend did bring scanner to my home and test but it show 3 gears is almost out but not tell me what I need to. They just try fix for money so I try get thur your question and with for answer.
