You really can't get better than a Tremec as far as a reliable, mass produced aftermarket transmission goes. They have the facilities, the engineers, the track record, the distribution, the warranty, ... So what, with the TKX you have to cut one tiny slit in the sheet metal and weld a little strip of metal for clearance. You can get one at your front door tomorrow morning from 20 different retailers and it's warrantied and has replacement parts ready for order. Oh, it's almost half the price! And better.

Passon should have just stuck with selling repair and restoration items. I don't mean that in any derogatory way either. I buy from him with any need I have that he can provide for in the 4-speed and pedals areas.
