What do you have, a 3.27 rear end gear ratio? My T-5 has the 3.35 first gear, and I run 3.45's in the rearend, and first gear is too high of a ratio (common term lower gears). So first gears runs out of steam too fast for me and I can't get as much traction, plus it is a little annoying only using first gear when you are absolutely stopped. Then the jump to 2nd is a big stretch, if I shift at 5500, I am looking at 3250 when I'm in second. My advice is to go with the 2.95 geared tranny with the lower rpm overdrive. First gear will definitely not be bad at all at 2.95
