TKX

I know you decided not to install a TKX but I thought I would add my experience with one. I had a shop convert my three speed auto to the TKX and I could not be happier. The transmission is one of the best I've ever driven. It shifts like the old toploader I had years ago in my Cobra replica but with the overdrive of 5th gear, I can cruise at 70 mph at 1900 rpm with 3:23 gears.
