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:

no way around it , necessary evil IMOP , and its been this way with every trans kit on the market to date , the notching takes a fair amount of time to take its toll and make the drum unusable at common pressures .

I never said there was a way around it. I never even said it was bad. But facts are facts, a harder steel WILL cut notches in the grooves faster then a soft steel.

Chevy1925 asked a question about inspecting his trans because it has seen some abuse for a while now. Mike answered by saying, "Reread my post. I don't use soft steel plates." The way I read it Chevy1925 was asking more about the drum then the clutches. But I could be wrong.

Opps my bad Mike, I ment the drum. Is the drum something to check down the road or is the wear such a minimal that i wouldnt be an issue for a long time. i can see how thats confusing in my last post, sorry guys :( :D :hug:

Eventualy it might become an issue, but not for a while. You are only running about 280 psi. Some of my Allis are running over 300 psi and that make the drum more prone to ring wear and notching. I have the answer for the ring wear using specialy made sealing rings but I don't have an answer for the notching yet.

what would be a good converter to use with the Gmax 6 pack or this new set up with twins for DD and occasional towing?

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.

Thanks Mike. I had no idea about the steels.

Someday Id love to hear your thoughts on two-sided vs one sided clutches....how they compare and what applications both are better designed for.
