Automatic transmission from 1974 Pontiac Lemans. Has BOP bolt pattern also fits Chevy. Was attached to original Pontiac 350 CID V8. Just to clarify... The guy at the salvage yard said he'd give me $30 for the trans because BOP is not as "desirable" as Chevy. He would give me $75 if the trans "was a Chevy." Here is what I have: it is an automatic trans from my 1974 Pontiac and was bolted to the 350 cid Pontiac motor, BOP bolt pattern on the "bellhousing." The trans also has DUAL bolt pattern--will also bolt to a Chevy.
