The 5R110W was introduced in 2003 to replace the 4R100 with which it has a similar appearance. These units proved to be fairly durable from the factory, but time and heavy use can expose a few weaknesses. The aftermarket has provided some clever solutions for these that turn a fairly durable unit into a very durable unit.

  • 100% Bushing replacement- corrects high wear area

  • 100% Updated pressure regulator valve, bore reamed to accept later design - Prevents shifting concerns & drop in RPM between shift points

  • One piece solid brass direct bushing - more longevity and less wear
  • 100% Dyno tested - reduces installation delays
