Only when cold and only on the first shift, but my '04 with only 88K miles clunks hard in OD when temps are cold outside. Fluid has been replaced and level is good. Any thoughts? Should I try some Lucas?
So I have the A750F in mine (5 speed) and it'll do that when it's cold outside as well. I always just attributed it to possibly TQ lockup or something of that sort, the transmission definitely becomes much rougher when cold though.
Then again, how hard of a clunk are we talking about? Mine when it "clunks" sounds/feels like something is pushing me from behind suddenly - it's more like a jolt.
