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!!!!

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.
