allison 740 tran

#1
I have a 1984 mc9 bus with a allison 740 and it works graet except for on thing, if I come to a stop sign fairly quick and then take off quickly the trans feels like its out of fluid and has a delay before the trans grabs (about a secound) if I wait about two secounds at the stop sign the trans will catch just fine, is this normal?

It sounds like it is not shifting down to first gear when it should. Ther are a few possibilities. It could be a sticking governor, low pressure at an idle, low idle RPM, or it could need a simple adjustment in your valvebody.
