I've went back over my book from CK. He says that if you're making more than 250hp, a must is to enlarge separator plate 2-3 shift hole to .140
In the Transgo instructions it says .093 for mild or .110 for wild
I'm going to go .140 and drill case to dual feed 3rd clutch.
This in theory should stop the flare shift on 2-3 upshift
If trans still does not work, a pressure gauge is needed to see if pressures are to spec
My flare is happening on normal accelleration. I've not tried WOT yet. This is to me a pressure thing
