Title: Tranny swapping
Post by: Go Roush on April 13, 2005, 01:42:37 PM
I have a 88 Tbird with a 5.0, but the tranny is slipping. Ialso have a 87 Tbird with a 3.8, and the tranny is good. My question is if the tranny behind both motors are the same except the bellhousing. So hopefully if needed I can use the 3.8 tranny behind my 5.0, with a bellhousing swap. Let me know, if anybody else knows.  Thank you

Bellhousing bolt patterns are the same between 3.8 and 5.0

3.8l trans will be much weaker though.

Are you 100% positive?  I recall someone on here using a 3.8 tranny without any problems.  If it's an AOD it's an AOD, right?

The NA 3.8 trans has one less foward clutch than a 5.0/5.8 trans. But still its gonna be a bunch better tha any slipping 5.0 tranny. The 3.8 Super Coupe trans I have, is actually a little stronger than a 5.0 trans...
