I am rebuilding a 94 42RH trans. It is all built except the O/D unit. I am using the ATSG manual as a reference. I've figured out that I have the "first design" level. According to the manual the steels I need for the direct/OD and O/D clutch packs should approximately be .070 thick. My mic puts them at about .065, which is close. I ASSUME I should buy the .070 thick steels? RockAuto lists many different thicknesses that are close to that (.068, .069, .070 for example). Should I order the exact size, .070 even though mine measure about .065 (wear? mic inaccuracy?, will that much difference matter?)?
Second question pertains to the friction plates. I am not seeing a thickness in the manual on which frictions to order. Mine measure .063 for direct/OD and .081 on the OD clutch pack. I ASSUME there has been wear since new, but should they all be the same thickness?
My clutch pack numbers are as follows:
direct/OD pack: 6 friction, 5 steels
OD pack: 4 friction, 3 steels.
I just need help figuring which thickness and brand I should get. I would like better power holding then stock (for about a 400hp 318, 3.55 gear, mostly street cruiser). I used mancini kit for the main trans rebuild with some SMR upgrades.
Thank you for the help.
