ever read on the board. Hats off! Excellent review of a common and expensive failure for ZF autobox owners like me. As to drilling the little relief hole...I am right with you. Best to not drill the hole. No less an expert than Kirt Koeller does not drill a relief hole in any of these transmissions he rebuilds either and he does a lot of them.
A question...if I were to run into this failure...do you now take on these repairs from forum members? Is so, what would be your price less shipping
for a standard rebuild of clutches and seals?
Many Thanks for your contribution Winfred...really good stuff.
