A904 Governor
Yep.Just what I did.I have a race tranny with a manual valve body in my car.A 65 B body. Switched it with a regular valve body.I had hopes that the governor was still in it.Someone else built the tranny.Made a call to A&A and was told that a manual valve body can be used with or without. The said you really can't see it, so pull the tail housing or take a 50/50 chance.I gambled and lost. Mine didn't have one.
