I am getting ready to supercharge my 2001 GT, I need to know can the stock tranny(t-45 I believe) handle the extra Hp and Tq ? If I must upgrade what is the best to use. If I can keep my stock tranny will it need any mods to keep it alive? THANKS!!

 

How much boost? You will probably be okay with a 6lb kit but how long will that be enough? Are you just driving it on the street or taking it to the strip? Just a couple of things to think about.

 

The stock tranny should be ok with what Redfiresnake said about the boost. Also, repeated trips to the track with 4500 RPM launchs on slicks will not keep it one piece too long, but 'spirited' street driving should be ok.

 

You guys are aware of the new TSB out for the TR3650, aren't ya?

 

Your car has the 3650, not the crap t-45. It should be ok with just street driving up to about 370rwhp. Anything over that is going to start really straining the tranny. Also if you are running drag radials or any type of sticky tire, it wont hold up to that long at any power level really. For a street tire, should be fine though for awhile.

 

THAT T-45 IS IN MY '96 COBRA AND IT ISSSSS A PIECE OF CRAP! THE 6-SPEED IN MY '03 COBRA IS A WORK OF ART! I CAN'T SAY ENOUGH GOOD THINGS ABOUT IT!

 

yeah you should be fine. just depends on how you treat it. if you launch hard and shift hard all the time with elevated power levels. it wont last long. but if you drive normal most of the time and just "play" from time to time the 3650 should last a while. break it, pull the blower take it to ford and say what the heck happened??? LOL

 

Sounds like you've had experience in this department.


haha

 

AMEN BROTHA! i've got a T-45 in my cobra and i hate it! The first change I get and have the $$ a X2C TKO is going in I think.

 

Good luck with that tranny swap Scot! Hey, did you take yours in for work when it was under warranty like i did? I tore up the synchronizers power-shifting all the time! hehe

 

HAHA, no but i thought it sounded like a good idea! b/c thats what i am going to do with the wifes 04. im either getting an 05 vert in march or whenever. or we are going to get her an 05mazda 6 and the 04 is mine! if they wont replace the tranny, then here comes T56!
