Governor Bore Plug Kit
Part No. 22771-14K

In listed Chrysler units, governor oil leaving the solenoid reacts on the 1-2 and 2-3 bore plugs, which sequentially stroke the shift valves. These bore plugs stroke relative to an opposing spring and variable throttle pressure. Bore wear creates a loss of governor pressure, which affects shift timing. Due to this wear, shift timing changes with operating temperature and often causes a shuttle or late shift. When this leak is combined with a governor solenoid and transducer feedback, they are often too slow to compensate for this oil loss. The throttle circuit is also prone to wear and has TV pressure variation from cross-leaks, which then affect shift timing. These cross-leaks often come from the 1-2 accumulator piston seals, throttle control valve, TV checkball and/or a distorted valve body. Installing Sonnax governor bore plug kit 22771-14K prevents critical oil pressure leakage.

• Kit provides improved shift timing
