GM Transmission Bolt Patterns
Posted: Thu Dec 24, 2009 2:51 pm
Bro Willy and I had a hard time identifying the bolt pattern on his GM 3.8L engines. Originally we assumed that all GM 3.8L/3800cc engines would have the same trans bolt pattern. Not so. Actually, there are three!! Here's the reference that got us straight. Now we can look for a transmission.

(He has the GM Metric, aka Small Corporate, aka S10 bolt pattern. One block came from a '94 FWD Buick.)
