Auto transmission problems, should I try to repair myself?
My vehicle has a 3 speed automatic, I believe the Turbo 400; had it rebuilt about 100,000 miles ago (25 years ago) and now having problems I will try to describe.
Accelerating up to about 30 to 40 MPH it will shift fine throughout all 3 gears; however, as I ease off the accelerator to cruising speed, the tranny seems to drop out of gear as if going into neutral. If apply a little acceleration, it will hit 2nd gear then go back into 3rd gear. If I am cruising at about 50 MPH or above, the tranny seems to stay in 3rd gear as it should.
A local tranny shop said $1000 to replace a part but I forgot what that part was. Iíve done almost all repairs to this vehicle since ownership in 1979 which included a complete engine rebuild. That said though, a tranny repair may be beyond what I can do. Iím not a mechanic by trade, just a mechanic hobbyist.
Any suggestions? If possible, I would like to try to repair myself and save $1000.
