Dual clutch transmission
 

Has anyone installed or even thought about installing a dual clutch transmission with paddle shifters? Is there one that would fit with reasonable effort? What do they cost? Likely to be significantly better than shifting the standard auto manually?

Tci has some for the sbc bellhousing but iirc they are almost 5k.

TCI doesn't have dual clutch transmission. They have the 6X thats available with paddle shifters. It just a 4L80 with two extra gears.

A dual clutch tranny would be expensive to purchase, and fabrication would be pretty tough. But with enough time and money anything is possible.

A guy in the auto-x club I'm in has the 6 speed 4l80e based trans and he's had a lot of trouble with it. He has to keep swapping his built 4l60e back in to his heavily modified El Camino. I thought of the dual clutch because I was looking at the Factory Five GTM kit car and it calls for a Porsche transmission behind the Corvette engine. I think this is a ZF trans with 6, 7 or 8 gears and dual clutches. It may be expensive (haven't found prices yet) but if it can be stuck in the FFR kit car it seemed like it could be adapted for 3rd gens. Of course the trans would cost more than the car!

The TCI 6X uses a different gearset (to get 1st further from 3rd, further from 5th) and overdrives each to get 2nd, 4th, 6th. Tripling the shifts a particular clutch-set or band goes through is to test the durability of it.

The use of a Porsche trans. in the FFR is because it is a transaxle for mid-engine applications. In other words, it's a quite different output location (to the differential ahead of the gearset) than your average 2WD thirdgen-friendly trans. And the one most commonly used iin the FFR is not a ZF, but is a few grand or more for the trans. alone.

The TR6070 won't be too bad to convert to slip-yoke use all things considered but I suspect it'll be a while before I have my hands on one.
