Excessive torque converter hub-to-pump bushing clearance in listed Chrysler transmissions is a root cause of code 38, TCC slip codes, front seal leakage, loss of prime code 35 and pump noise. The OE bushing is machined in place, allowing a wide tolerance on pump housing bore diameters. Bore diameters can vary by more than .003". This wide tolerance is a problem when using standard replacement bushings. Standard replacement bushings will often have .008" or more hub-to-bushing clearance with an average 10 times more oil loss than Sonnax pump bushing 12502-01.
The Sonnax bushing will restore the clearance necessary for proper operation. It should only be used when the housing diameter is greater than 1.6175".

Allows precision clearances with wide tolerance pump bushings
No machining required to restore correct clearances
