i have an 84 cutlass supreme, my trans has 11 bolt pan and doesnt shift to second. i have an extreme cam. 292h. just droped a 600 holly on top. guess what i want to know at this time is should i fix the trans i have or switch it up, and does any gm trans bolt up?

 

What motor are you running? If it's an olds motor only a BOP tranny will bolt up. No chevy trannys. Might take a pic of the pan I'm not familiar with what pan has how many bolts.

 

Which transmission needs to be figured out.

Could you provide a picture of the pan? Can you describe the shape of the pan? What letters are on the shift indicator in the dash P _ _ _ _ _ _? How does the fluid condition look? Was anything done to the car such as carburetor/linkage repair before it stopped upshifting or did it just stop upshifting?

 

square pan with cut corner. i believe its a th200. 307motor. what is BOP? P R N D 2 1. skips second shifts to third. it stopped shifting to second after i put the ridiculously big cam in. been reading looks like i want to go with a th-200-4r

 

BOP = Buick Olds Pontiac. Chevy Bell housings are shaped differently. BOP does exclude Cadillac which did use a BOP configuration. I believe that some of the Cadillac TH 400's would work in Buicks, Olds and Pontiac if the tailshaft was the correct length, probably worked in the large body cars only. There is a universal case that does fit all of the configurations.

How do you know it skips second? Is it possibly not going into first and shifting from second to third? Will it go into second manually?

The problem may be with the cable adjustment to the "TV?" cable on the drivers side at the throttle linkage since the carb and intake have been removed to replace the cam. Vacuum changes from the camshaft should not matter on a 200 transmission because they do not use a modulator IIRC.
