I don't think that this will cost a bunch more than what they cost now. A bit more, maybe. But not too much.

That may be true, but $10/hr don't provide much in the way of spending. I just got my tax return and am about to get EFILive. Just need to figure out who to get it from. Back OT, When I do get enough $$$, I will be sending my whole trans to Mike and have him do his thing on it.:woott:

So you'd still use the stock steels?

Allison stock steels are made of very soft metal because it saves on tooling wear. Problem with that is they heat check and wear rapidly. If you ever get to see the clutches on a stock Alli, you will see the steel plates machined down and the frictions intact. Unfortunately the front drum is made out of the same soft metal and you will see notches in the grooves where the C2 steel plates ate them out. You will also see ring groove wear where the stator support rings ate out the drum if you run high line pressure.
I use hardened steel plates which will minimize the steel plate deterioration and I will have a new pressure regulator kit which will be adjustable for your needs and a new mod to eliminate the drum damage from high pressure.

Is this something to worry or check down the line after puttin so many miles on a built alli? just out of curiousity :D

After re-reading his post he is talking about the front rotating assembly, which in your post you said you have had issues with the grooves that hold the steels getting notches cut in them. If you are using steel plates that are harder then stock that will only make this problem worse, honey.:hug:
