Auto for Autocross/Track Days

[Simmo]

I have to make a call on transmission choice fairly soon and have a dilemma.

I've always had manuals for any type of performance driving, but I've now got a bung left foot and a t56 may not be a viable option (depending on how my recovery goes in the next 12 odd months). I need help from those who run/have run the following:-

I've checked out TCI's 6x trans and like what I read, all aside from the apparent lack of a positive downshift and the cost. A paddle shifted 4L80 may be the next best thing. Is anyone running one of these options in autocross/track type situations? How does it perform? Downshift? Shift response?

If someone has come across any options to retain the t56 but do away with the foot-operated clutch I'd also like to hear from you, I found one push button option at $8500, not really viable!

The Elky will be a bit of a do it all machine - street, autox, track and drag. The auto being an awesome option from the latter, it'll need to perform in the other diciplines as well though! I aim for about 450rwhp initailly, but may go FI later on so want future proofing for that too.

Any ideas?
