The TV bore wears out easily in listed Chrysler RWD transmissions, with the 48RE seeing much higher rates of poor line pressure rise and inconsistent shift timing compared to earlier units. Ideal for bores with minimal wear, Sonnax throttle valve kit 22771-03K is a basic durability enhancement with an optional balance spring to help revive throttle control.

  • Repairs bores with with minimal wear
  • Hardened steel plunger and valve increase durability, especially in 48REs
  • Optional shims and TV spring for custom TV pressure adjustment and tuning
