As posted at Stangnet....If you're having problems please join the group and
post email your info to Dwayne. (so far we're up to 100 people)

I got a Lawyer for us on the Tremec 3650
Ok Guys here is the deal I do computer work for a lawyer in our office
building, and am good friends with him, I talked to him about this problem, and
he told me to get as many people aboard as possible and he will take action
from there.

E-mail me: ad...@sonrich.com your

Name:
Year Vehicle:
Problem:
contact info: e-mail , phone number, or whatever.

He told me to get VIN numbers also , but if you guys fell unsure about that you
dont have to, the only reason he recommends that is so they can tell what
tranny make times are in the cars that have the problem.

Put tremec 3650 in the subject line

My Lawyer told me if I can get close to 500 people to send me info He will take
the next step towards action into getting our problem resolved.

We are going to send a formal petition with everyones names and problems to the
NHTSA, FORD, and the Michigan ATTORNEY GERNERAL. He told me if there is a
problem and I have documented proof that Tremec aknowledges there is a issue, I
have 2 e-mails from them, from 2 separte technicians. We can take action , but
we all need to come together.

Lets not lay down and take it guys, we can make a difference!!!

I just read some of the thread at stangnet that he referred to. Seems that
the difficulty shifting into second when cold is more pornounced in some
cars. In many cases there is a grind when shifting into 2nd or 3rd that
never goes away. Bent shift forks and complete tranny failure have been a
couple of the other issues.

Afraid to drive my 03 when it's cold.

Funny, nobody thought to change the transmission fluid to redline
synthetic...............This would have been my first thought..............

Hmm. I do have that 2nd-3rd grind if I shift too quickly when cold. I
figured that was just the problem - shifting too quickly when cold.

I do have this 3650 in my 00 GT don't I? Or is that a different
transmission?

It's always been notchy as hell. Never shifts smoothly into or out of
gear.

Ford replaced the tranny and it was a LOT better, although the problem
was still there. However, it wasn't worth bothering with.

Well generally..you spend 20k+ on a car...you shouldn't have to change
transmission fluid to fix a problem with it. Matter of fact...there
shouldn't be a thing on the car you have to touch and modify for the
car to operate properly.

The problem is with Tremec 3650 5-speed transmissions used on Bullit
Mustangs and mid-year 2001 GTs through the present. Cold and warm shift
problems engaging 1-2 and 2-3 gear shifts. Grinding is common among many
owners, myself included. Changing to Redline D4 does not cure, but can
improve the issue slightly, from others experiences. I've nearly been rear
ended by closely following vehicles when trying to accelerate away from
traffic lights or stop signs because 2nd gear feels blocked by something in
the way of the stick (warm or cold). Not expected from a Mustang. Even with
this fault I love my '01 GT with the Tremec 3650. Wish this problem could be
solved. That is the goal of the potential class action suit.

T3650s came from the factory with Mobil1 Synthetic. The only reason I
can think of for switching to Redline would be for extreme heat
conditions as that seems to be where Redline shines. This doesn't
seem to be the case here.

How many of those "hard shifting" issues also have an aftermarket
shifter? How many actually have the T5 but think it is the 3650?
Hard shifts were common with the T5. I see some reponses here that
are clearly T5s.

Why would there be a T5 in a car that comes with a Tremec 3650?

Since I started this thread. My Tremec is stock, including the shifter. I don't
even ride the car hard. The notchy feeling between 1-2 is there mainly when the
trans is cold.

I had the car into the dealer over the winter and they changed the trans fluid,
but of course it didn't fixed it.

I'm really not looking forward to next winter when this starts all over again.

T45, not sure what I was thinking. That's what came in pre-'01 Cobras and GTs.

No, you have the wonderful T-45 trans. Basically a weaker version of the
T-5 in my opinion. ;-) Tremec 3650 transmissions were used starting
mid-year '01 cars.

I have one in my '97 Cobra. I absolutely can *not* hit 2nd gear under any
kind of speed shifting, even lifting the throttle, without catching a few
teeth on the way in. I wouldn't even try powershifting as I'm sure I'd
break something. Ford says there's nothing wrong with it because if you
push the clutch all the way to the floor and then shift, it doesn't do it.
I've had it crunch a couple teeth even doing that while shifting fast, but
since the clutch grabs in the last inch of travel, pushing it completely to
the floor shouldn't be necessary. I had a 4-speed SROD trans in an '83
Capri that I used to speed-shift without ever crunching gears while only
pushing the clutch down half-way. The mechs at Ford seemed to think my T-45
was normal.

IMO, it's just in there biding its time until I have the cash for the T-56
setup.

The Tremec 3650 was supposed to alleviate some of the problems that the T-45
was having. The T-45 has had numerous problems with 2nd gear synchros and
shift forks.

I was able to eliminated the shitty 1st->2nd speed shift problems with
installing a pro 5.0 shifter..besides the nice crisp short shifts...it
also eliminated the speed shift problems.

And after shifting the piss out of it for 60k miles...still shifted
like brand new.

Exactly the same thing I did with my 02 GT.

The day I got it back, things seemed ok; but it got bad again. I started
parking it in a heated garage, which helped, but even at 70 degrees, it was
still somewhat difficult to shift.
