A999 lockup transmission. The good news is that they have the lower first gear for a bit faster launch. The bad news is that there is a TSB for shudder on these as the lockup occurs. Unfortunately the parts for the fix are no longer available. This kit has the fix built into it:

I used it for the shudder fix, tossed the rest. Used the Transgo shift kit TF2 to do the normal shift kit fixes on the transmission. I did this 4 years ago and it is still running well.
If you drop the valve body, it will have a growth on the top side that channels the fluid to the lockup circuit so valve bodies will not interchange to the 904.
BTW, I did change the the torque converter as was suggested before.
