Hi All,
I bought a really nice Cherokee last fall after searching for 2 years. Ran great, interior was amazing. 124K. Then my engine developed crank walk.
After investigating it, I am going to swap in a replacement 4.0, but before I do that, I want to figure out what caused the crank walk.
So, I took the XJ to the shop today to have the the transmission cooler line pressure checked.
The pressures were high. The tech adjusted them down as far as he could, but the FORWARD pressure is still more than the max spec.
Should I be worried about this tranny destroying another engine? Is there anything else I can do?
Note: I have already ordered a new torque converter in case that had been balooning and making things even worse.
Results below:
FORWARD PRESSURE
BEFORE: 270
SPEC: 161-196
Discrepancy: 74 Over Max
AFTER ADJUSTMENT: 210 (14 Over Max)
REVERSE PRESSURE
BEFORE: 320
SPEC: 223-273
Discrepancy: 47 Over Max
AFTER ADJUSTMENT: 270
Thanks in advance.
