4R100 transmission line pressure specs?

Can anyone tell me what the line pressure specs are for a 4R100 transmission? Or point me in the right direction to find this info? Thanks

You found this in a book or testing of your own? Thanks

Re: 4R100 transmission line pressure specs?

According to ATSG the 4R100's line pressures=

P,N 50 to 60psi at idle
R 70-100psi
OD, M2 50-65psi
M1, 70-115psi

and the pressure jumps from175 and all the way to 240psi at stall.

Hopefully soon i can afford to overhaul my tranny because it took a giant #### on me. I'll post the build when finished, but it's gonna take a while?
