hi guys. i just bought an 06 enthusiast auto. it now has 1300 miles on it. I just started noticing when i put it in tiptronic mode i hear a subtle clunk on the 2nd-3rd shift..all the other shifts are smooth and noiseless. If i leave it in drive i don't hear it at all. any others hear this? what could it be? thanks, tristan

 

There was a thread on this topic in the past.

Maybe you can do a search for it.

 

Here is the thread. It is perfectly normal. The tranny and TC will respond differently when you are shifting at partial or WOT.
