Guys,

My Dad has a 99 Cobra, long story short, the transmission got stuck in 4th gear on normal shifting today, had to be towed home. It will not come out no matter what.


Question is, what all is needed for a Tremec-3550 swap? He has a tr-3550 in his 94 GT, and we need to know what parts to order ASAP so we can drop it in the Cobra this week.

Also, what transmission came in a 99 Cobra stock? 3650? T-45? Is it worth having that rebuilt, go ahead with the 3550 swap.

Thanks in advance.

i dont think they make the 3550 anymore. for the swap all you should need is the bell housing

Nah, he HAS a 3550 already, so he wants to put it in his Cobra.

What about the clutch? Driveshaft?

99 cobra had a t-45

as far as the swap to the tr-3550 I am not completely up on that.

I would not rebuild the t-45. now is the tr-3550 stock?

The 3550 is from his 94... Not sure how stock/nonstock it is.

Hmmm, I'll see what I can doa bout talking him into selling the Tremec and getting a T-56

they put in tr3550 on 95? I thought 95 was T-5???
99 Cobra would have T-45. 95 would be T-5.
T-5 in 99 cobra would be sort of stupid(thats if they fit. I'm not sure), as T-5 will not handle the torque of DOHC. Remenber, they used T-5 on 99+ V-6
T-45 in 99 would have electric speedo pick up, and T-5 would be mechanical speedo pick up
we need more info on your situation. has trans in all these cars been replaced in the past?..

As far as TR3550 in place of t-45, I think u'll need bellhousing, clutch assembry, clutch linkege, and i think fly wheel is okay. driveshaft should fit.

Anyone can chime in?

Or TKO. Unless your making alots of power I heard that T56 will actually slow you down, due to gear ratio

well I read up on the tr-3550 a bit and it has a sufficent torque rating so It would be fine as long as the swap was not a pain. I could not be any more painful than a%

I'm not 100% sure but i think the 3550 input shaft because it's the wrong size

Mity2: The stock transmission in a 94 GT was the T-5, correct, but it currently has a Tremec 3350 in it.

He's going with a T-56 setup now it looks like. I calculated out the cost to buy a bellhousing for the Tremec, etc, and in the end, it wasn't enough more to go with the T-56 to make it worth doing the tremec. Like $700 difference between a used 5 spd, or a new 6 spd.

I think that he will be a little happier with the t56 setup in the car. Good luck on the project and let us know if there is anything that we can help with on the tech side. Good luck

I'm sure everyone else would too, BUT this looks like a budjet build...
