Need a transmission guy.
Just killed the thrust bearing in a new engine, 3rd time.
Twice with the old engine.

People keep pointing to the transmission cooler pressure.
I need someone to look at the readings I got.
Let me know if there is a problem.

Pressure line to the cooler;
Engine @ idle Engine RPM @ 2000
P-0 P-5PSI
R-25PSI R-50PSI
N-45PSI N-48PSI
L-28PSI L-42PSI
2-25PSI 2-50PSI
3-28PSI 3-55PSI

RETURN LINE

P-5PSI P-8PSI
R-40PSI R-45PSI
N-40PSI N-40PSI
L-28PSI L-45PSI
2-28PSI 2-45PSI
3-35PSI 3-45PSI

MAIN LINE PRESSURE FROM THE CASE

ENGINE @ IDLE ENGINE @ 1500RPM
P-5PSI P-14PSI
R-5PSI R-14PSI
N-5PSI N-15PSI
L-5PSI L-15PSI
2-15PSI 2-29PSI
3-15PSI 3-16PSI

Anyone know if these numbers are good?
