Rebuilt A998 - No upshift/only 1st gear

olei said

Thanks for your reply.

The ATSG manual says that both a faulty front clutch and worn/broken reaction shaft support seals can result in no upshift.

Are teflon seals still prefered compared to the steel ones? Who sells the steel type?

What do you think about the hydraulic pressure test results?

When that front clutch engages you should hear a definite "Thunk" (not "I think I can hear it")

I have been out of the trans business so long I can't really comment on the pressure test other than it seems reasonable (can't get specific)

The one thing I always disliked about using Teflon was that it wears the steel and iron parts worse than metal rings.
Other than that I can't really argue that they work fine, just never liked the idea I guess.

(they have really good prices also)
