Either a TH 200 Metric or a TH 350. Either will bolt right in place of the other. If you have the choice, use the TH 350....much stronger transmission. You can also use a 200-4R 4 speed auto or a TH 400.....but these will require a different cross member.
YES IT WILL
A 350 Oldsmobile engine has a different bolt pattern than the Chevrolet engine. The 350 Olds and 350 Pontiac engines have the same bolt pattern. The 350 Chevrolet and the 350 Buick engines have the same bolt pattern. Unless you have a dual bolt pattern transmission (there are some out there) in that Chevy, the Olds engine won't bolt into the Chevy transmission.
Turbo 350
84 and 85 cutlass's came with olds 307 small blocks. and others came with V-6's. now an olds 307 will slide right into a 72 cutlass (i have one also (: as long as the cutlass was a v-8 (olds 350 rocket and olds 455's were the v-8s that came in the 72's.) so yes the bolt pattern on the tranny and the engine mounts will all match up with the 307 if the 72.
yes it will bolt to a 350
ANY transmission will fit as long as it has the B O P (Buick, Olsmobile, or Pontiac or Cadillac) bolt pattern. Be it the 200, 350, 700 ........
Pontiac didn't make a 307. If it's an Olds 307, you need an adapter or a BOP transmission.
a BOP turbo 350.
yes same bolt pattern
If memory serves me right, back in the early 70's the Chevy V8 and the Buick V8 shared the same bell housing bolt pattern. The Oldsmobile V8 and Pontiac V8 shared a different bolt pattern. But, back then GM did have a turbo 350 transmission that had two bolt patterns that would bolt to all of their V8's and some of the vehicles were produced with that transmission. Whether or not you have that double pattern transmission you probably won't know until you take it apart.
Only if the transmission has a dual bolt pattern. Chevrolet and Buick 350 engines have the same bolt pattern. Oldsmobile and Pontiac 350 engines have the same bolt pattern. There were some TH 350 transmissions that have dual bolt patterns.
