supposedly you can use the tcm from a 92-93 or one from a van

Its possible, Ive (actually my brother) has done a few. My 96 still has a TCM. It is alot of work to make it factory smooth. We spent months on the first one and got it down to a point that no wires are cut.
BUT!! I dont recomend it as you can now buy a OptiShift for less than $600. You will have more in a TCM convertion just in time, design and agravation than $600. Let alone if you buy a TCM.

I do sell the OptiShift also.

You can download the optishift 'shiftware'.. Screenshot for 4L80 diesel.. It looks alot like what the graph would be for my '93 (oem) as far as speeds/gears. Cool device.

your better off with the controller with my conversion i used the factory tcm, to much aggrevation.
