Thank you for your reply.

I don't know if it does it at higher speeds as she drove away without me. I will do some testing tonight on the way home.

I doubt its tranny or wheel related as when she pulled away I heard it in the exhaust. Perhaps studdering is a poor choice of word, but I don't know what to use. Perhaps missing is the best word in this case. I'll clean the TB this weekend and give everything a good visual inspection.
