Auto Parts: 1992 Chev van transmission, vacuum modulator, pep boys


Question
We had our transmission rebuilt just before leaving on a long road trip.  It is not shifting properly until we are up to a fairly high speed.  It might be up to 40 KM/Hr. plus before the first shift.  Once it is up to speed it runs along fine.  Do you have any ideas about what could cause this problem?  Will driving it this way damage the transmission?

Answer
Hi Barry,

Bad vacuum modulator or sticking governor. I'd lean toward the modulator. Take it back to the shop you had it 'fixed' at and ask them to do it right this time.

Looking for a reputable service technician? My advice on finding a good technician is: Steer clear of the dealership and 'chain' stores like Firestone, Sears, Pep Boys, Monro Muffler/Brake, Midas, etc. as they usually only employ ONE ASE Certified Tech just so they can say they do and chances are, that guy is the asst. manager or manager and is not in the store to diagnose/repair vehicles anyway. Find a service location in the link below or get some names out of the yellow-pages and do a drive-by. Garages that employ ASE Certified Technicians will be marked with the 'Blue-Seal' insignia. If unsure about whether a place employs Certified Techs, just ask to see their credentials. ALL ASE Certified Technicians will be PROUD to show and display their certificate(s).

Thanks for the question, I hope this information was helpful to you.
