I have a odd question. What is the pressure in the transmission lines? When I do my trans swap I'm going to replace the rusted lines with braided lines. I know the fittings are 3/8" but I need to know what pressure I should get the line rated for.

According to the ATSG manual.

Min
P,R,N 79-101
D4,D3,D2 74-86
D1 146-187

Max
P,R,N 223-271
D4,D3,D2 167-203
D1 146-187

wow that in the cooler lines wow. AN- line it is

I've seen them go OVER 300 PSI on a full throttle in Reverse!!

who goes full throttle in Reverse. ha but I do know now I need at least 300

I few of us have been known to do stuff like that from time to time!!
