yap..

up to 1995 was a Tremec t5
1996-mid 2001 was a t45
mid 2001 to now is a 3650 which was first given to the cobra's..

as for you answer 2000GT-5spd, if it's the original tranny ..it's a t-45 .. :)

I'm not pissed off. All I knew was the last time I was under the car I was surprised to see what it said on the case of the tranny also. I did not know that tramec has bought out Borg Warner until last night.

No hard fellings here.

I did some digging and found this information on Modular Mustang's site on how to tell a T-45 from a TR3650 -

As expected, I have a T-45 in my 2000GT.

ok guys, i was getting frustrated reading all this so let me set it straight......borg warner built the t-5 tranny until the arrival of the t-45 in 1996(also borg warner). In 1999 the company TREMEC began making the T-45 TRANSMISSIONS different company, same thing...... the tr-3650 came sometime during the mid 2001 production, also made by tremec. hope that helps. also, the newer 3650s used a larger clutch.

The T-45 was used starting with the modular engine program. In
mid 2000 model year the t-45 was phased out for the stronger
t-3650 model both of which are made by tremec. The t-45 is marginally stronger than a t-5 while the t-3650 is a fairly stout piece for a factory transmission it even comes with internal shifter stops to prevent bent shift forks that were so common with t-5's and t-45's
