I would like to see how these hold up in the long term. I'm not a fan of 3-pinion planetaries or of multiple-event shifts, but the torque handling numbers and close gear ratios are enough to keep an open mind.

There are three different bellhousings that I know of.

1. Torque tube bell for Corvette
2. Small bell (flat on top) for Cadillac
3. Big bell with standard SBC/BBC bolt pattern.

I have heard the controller for these is onboard. I have no idea how they get electronics to live in AFT, but apparently that is exactly what's happening. The transmission will take external inputs from the PCM (TPS, Brake Switch, tach, possibly MAP) and it will provide current gear (PRNDM1) and VSS. The "M" mode of drive will be a manu-matic up/down mode selectable by steering wheel or shifter controls. I cannot confirm this controller information.

The interface with the PCM will be similar to the way the Allison works with the HD trucks. The trans controller is external from and linked to the PCM and capable of commanding the PCM to run the engine in limp mode.

I thought they were going to put this tranny in the base C6 with the LS2, the XLR, and all the new GMT-900 trucks and SUV's. They should make it standard across Cadillac's entire lineup too.

I am just letting you know what I found on another web site that seems to get this info quicker than any of the other forums I've been to.

If GM is doing this obviously it was planned so the car would already be fabricated to handle this trans that apparently isn't much bigger than a what they are already using.
