Auto Parts: Engine Swap, chevy lumina, drive ratios

Question
I have a 96 cutlass supreme came with 3.1L V6 with roller rockers.  Unfortunately, the engine overheated and blew the top end.  Question?  Can a 91 Chevy Lumina with a 3.1L V6 engine and transmission be swapped out without to many obstacles.  The only one I see so far is the tranny connection.  Cutlass has a floor shifter and Lumina a column.  Thank you for any information.

Answer
Hi Vikki,

Unfortunately the PCM in your 96 will not operate the 91 transmission which is NOT electrically shifted. The interchange application for the 96 Olds includes 96 & 97 vehicles only so the unit is not backwards compatible and likewise, the 91 will not shift if installed in the 96 because of internal modulator differences and final-drive ratios.

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.
