Does one tranny seem to be more reliable than the other?

Sounds like another premature ZF failure. To answer the question about are some trannys more prone than others to fail, it would appear from this forum that ZF trannys (most, if not all, V8 models) are about 10 times more likely to fail than the GM trannys (most, if not all, 6cyl. models).
