A340E A343F Transmission Shift Solenoid for Jeep Wagoneer w/4.0L Eng 1987-1990
This A340E A343F transmission shift solenoid controls hydraulic flow to engage gears in the AW4 automatic transmission for Jeep Wagoneer models with the 4.0L engine from 1987 to 1990, serving as a direct replacement for the original solenoid's function.
Overview
This A340E A343F transmission shift solenoid is an electro-hydraulic valve that regulates transmission fluid pressure to shift gears smoothly. It is designed for Jeep Wagoneer vehicles equipped with the 4.0L engine and AW4 transmission, restoring proper shift behavior when the original solenoid fails.

Good To Know
Q: What are common signs of a failing shift solenoid? A: Common signs include erratic shifting, stuck gears, or transmission slipping. Replacing the solenoid typically restores normal shift function.
Q: Can this solenoid be installed without removing the transmission? A: In many cases, the solenoid can be accessed from the transmission pan, but on some models removal of the valve body may be required. Confirm access before starting work.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
