I would like to hear any 1st hand experience with a TKO 500 if anyone is using one. Mainly interested to hear how well they REALLY shift, especially at higher RPM (6800 ish).

This hasnt been a real good option for me until recently. Quick time now has a SFI bell for the 2.3 that comes with the T5 and TKO patterns. I am ordering it and will start with the T5's but am seriously looking at the TKO as a next step. I can get it with a 10 spline input (needed for my clutches) and it has a 3.30 ish 1st gear. I can swap back to a 4.10 rear (or even 4.30) and live with this I think.

I've not paid a lot of attention, but seem to remeber talk of some of these not shifiting well. I would rather blow up T5's than not be able ot power shift a new tranny.
