Post any valuable information you can contribute to the normal transmissions you find in 96-04 GT/Mach 1's along with Cobra's.
Information about swaps, rebuilding, hp/tq capabilities ETC....!!!

T-45 transmissions:
Do NOT powershift a T-45. I would also not recommend speed shifting a T-45 into 3rd gear. I have been thru 2 T-45, with the second one only lasting about a year.
These transmissions have a weak syncroniser, espcially in 3rd. My 2nd one was doomed after one speed shift into 4th that didn't quite make it. It was only a matter of time till I lost both 3rd and 4th.
I guess what I am saying is take it easy on T-45 equipped cars (I believe they are in the 01 and down??)
Also, if you do ruin your T-45, and plan on getting LT headers, just get a more reilable trans like a 3650 or a TKO. You must remove the headers to remove the trans, so you only want to do it once if at all. I learned the hard way!!!!

Maybe if your powershifting with the mods you have below. Normal-Bolt on cars shouldnt have problems powershifting a t-45. They dont seem to have problems until you get in the 350+ Flywheel HP range.

I tried power shifting my 03 Mach from 2nd to third at 5K RPM and hit the wall. It just would not go into 3rd. I had Ford replace the clutch with a beefed up clutch, and put in a Steeda short throw shifter. That helped somewhat, but then I got a recall from Ford to replace the guts to the tranny to include new beefed up syncronizers. That did the trick. I can now shift from 2nd to third at any speed over 5K RPM.

Crap... really ?? I've 1-2 powershifted my T45 at least 50 times in the past month. It's still OK.. same as when I bought it.. SLIGHT grind when slow shifting to 2nd.. but I got a warranty with it so I'm not trying to be too careful with it.

The second trans acutally lost the sync in 4th, but a healthy shift into 4th one day (it would still go in, it would just grind a bit) resulted in a loss of both 3rd and 4th gear. This is why I ended up spending this summers supercharger money on a trans/clutch and assorted gear to make it work.

Mine does in first, less so in second, and barely audible in third... silent from there on up. Not a lot of noise, it is noticable though.
