View Instructions

Severe wear of the TC pressure regulator valve bore results in leakage of converter release/lube/cooler oil pressure that compromises unit durability, resulting in damaged TCC linings, overheated converters and lube failures. The Sonnax kit 122892-10K salvages these valve bodies.

  • Salvages valve bodies with worn TC PR valve bores.
  • Restores normal converter charge and cooler flow.
  • Corrects harsh or no TCC apply, TCC slipping and burn-up.

This kit also services Jatco FP series; Ford JF506E, FPH; Jaguar JF506E, FPD; Mazda JA5A-ELFPF1/FPF2; Rover JF506E, FPO; and Nissan ZY units.
