Below is the response from Tremec (ttcautomotive) on the clunking issue that many of us are experiencing and underneath that is my orignal note. Please give me some input on how to respond. I want to keep it friendly. I will post all correspondence between myself and Tremec. Thanks, John.

In regard to the information that was forwarded to this office, I would like
to give to you some information that was given to me by our TR3650
transmission engineer.

The clunk sound in this case is not the transmission. Several times in the
late development of this transmission, we went through the total backlash
measurements to show that the transmission was not the cause. This seems to
be more related with other parts of the car, ie..axle, engine. The one main
thing to remember is that no other noises pertaining to the driveline of the
car has only one chance to enter the vehicle and this is through the floor
board by way of the shifter. Noise will travel and ultimately it ends up
traveling through the transmission and into the car from other points.

I hope that this answers your question and if you have any further question
or concerns, do not hesitate to contact me.

Thank you

Subject: TR 3650 Tranny

Hi. I am the proud owner of a 2001 Ford Mustang Bullitt. This would be a
perfect car if it were not for the tranny. I have taken it back to the
dealer several times for clunking. They just tell me this is typical of
this transmission. That's bull. You don't pay $27K for a new car that
has a tranny that clunks. My 94 Mustang GT's T5 never clunked. You guys
need to come clean with Ford and solve this problem regardless of cost. The
message boards are full of Cobra and Bullitt owners complaining about your TR
3650. I would venture to say 2 out of every 3 clunk or have a hard time
shifting from 2nd to 3rd (or both problems). Go to and
check out what people are saying. Also check out the 2001 Cobra forum on . How about posting some explanations on these
