Title: Excess pressure in trans while in park and idling maybe
Post by: wideopen231 on May 26, 2018, 01:55:50 PM

SO fired off FED  today and only one real issue.It blows coupling out of trans(no driveshaft) while at idle and in park. I know the guy who built it screwed up something.Anyone with idea what I did or didn't do. Maybe I am wrong and there is more pressure pushing against coupler then I think. Would seem should be almost zero.

Go almost 30 years between PG builds and you will make a mistake. Last car I had a glide in personally was 1989.Not the same as Lenco.LOL

Thought was gasket. But checking depth in case vs. covers step seems cover is already +.010. Will not seat if gasket is installed,guess machined so as not to need?. Was told by another trans guy he has seem plenty yokes pushed out on dyno and probably nothing to worry about.  Hard not to get nervous when its parts you have most money in on whole build.Motors don't count since they where sitting here anyway. Ask my wife she has been told that enough.LOL
