  • Salvages pump bodies with worn pressure regulator valve bores.
  • Restores normal line pressure, eliminates related shift problems and restores cooler flow.
  • Repairs both early and late versions of 5R110W pump bodies.
WARNING:

A specially designed oversized base plate VB-06 must be mounted to the VB-FIX to accommodate the 5R110W pump body.

NOTE:

Three pump generations were produced, with varying casting hardness. The Sonnax reaming tool kit used must be matched to the hardness of the pump to extend reamer life and bore finish quality. Sonnax reaming tool kit F-36940-TL3 is for use with first generation pumps, while F-36940-TL3C can be used with all pumps regardless of pump generation. See instructions for details.
