What type of transmission came on a 1980 cutlass supreme?
A 1980 Cutlass Supreme could have come with either any one of these Turbo-Hydramatic transmissions: TH200C, TH350, TH350C, TH375, or TH400
From what I have read at Automotix.com , I will say yes it will. You also have other options of engines from Chevrolet, Buick, as well Oldsmobile that fit the Cutlass Supreme. The engines vary from V6 3.8L, 4.3L V6, 5.0L V8, to 5.7L V8, depending on what year and transmission type your Cutlass Supreme has.

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, an Olds 350 will fit if it's the rear wheel drive Supreme. It is the same basic block as the Olds 307 c.i. engine that came with some Cutlasses. Another option was the Chevy 305 which of course is the same block as a Chevy 350 (another possible option) if you are so inclined. An Olds 307, 330, 350, 403, or even a 455 will fit. The 455 will be tight and will need…
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.
