Can't help with full specs, I also did the mods to mine off the info in this thread
The oil pressure for the entire box also runs of an adjustable actuator which is all ready set to the highest setting but can be modded (very easy) to go up one more step. 1.5mm thick triangle of alloy made in 5min from scrap I had lying around
I'd never seen the inside of an auto before an managed to do this while the auto was still in the car.
I did find this pic which is one of the originals from this thread.
From memory mild steel, 21mm x 8mm thick
8mm is in no way overkill, I expected it to chirp the tires but it doesn't
If I ever did this mod again I would pull the trans out, empty oil etc, turn upside down and do it on the floor.
Working under a car with auto trans fluid dripping in your face is no fun
And man what a difference!!! I'd suggest to anyone to do these mod's,
pulls harder & changes gears much cleaner.
I will have a better look through my pic's for other photos, I did take pic's of my auto apart but it's a bit hard to see and somewhat blurry in places
