Symptoms:

  • Pump seal leakage
  • Pump noise
  • Loss of prime
  • Low pump volume
  • Low cooler flow
  • TCC codes
  • Switch codes

Cause:

Pump body bores vary in diameter. Standard replacement bushings often result in excessive hub-to-bushing clearance.

Correction:

This improved fit replacement bushing restores proper hub-to-bushing clearance.

Excessive torque converter hub-to-pump bushing clearance in listed Chrysler units 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 the Sonnax improved fit bushing 12502-01.

This bushing will restore the clearance necessary for proper operation. It should only be used when the housing diameter is greater than 1.6175", which will be in most cases.

  • Allows precision clearances with wide tolerance pump bushings
  • No machining required to restore correct clearances
  • Bushing Style: Precision
  • Material: Steel-backed bimetal
  • Width: 0.535"
  • Shaft Dia.: 1.498"
  • Housing Bore: 1.619"
