Hey all,

I just picked up an '07 XLT. Third Expy now.

It seems to be working fine, drives very smoothly generally. Shifts in an out of 4A without any complaints or noises, when we're stopped or moving.

The only oddity is a bit of a thunk when accelerating away from a stop and in 4A. I don't think it does it in 2H. Same sort of noise/thunk a small blip in the road, normally around the change up into 3rd gear, around that area, not always the same point.

Any pointers on how to check or diagnose it?

Mostly it's very smooth. My wife drove my '03, then this one and commented on how much smoother it is. Just want to make sure that if there is a problem I can sort it out.

Thanks,

Alex
