The only solonoids on the 4.0L are torque cinvertor clutch solonoid and the 3/4 shift solonoid?

ELECTRONIC SHIFT CONTROL SYSTEM
Electronic Shift Operation
System consists of a push-button or rotary dial control, electronic shift control module, electric shift motor with integral shift position sensor. System also uses inputs from vehicle speed sensor and transmission range sensor (A/T) or clutch switch (M/T).
Transfer case is equipped with a magnetic clutch, located inside case next to the 2WD/4WD shift collar. Clutch is used to spin-up front drive system from zero to vehicle speed in less than a second. This spin-up allows the 2WD to 4WD shift to be made at any speed.
When transfer case rear and front output shafts reach the same rotating speed, spring-loaded shift collar mechanically engages mainshaft hub to chain drive sprocket. Magnetic clutch is then deactivated. Shifts between 4WD high and 4WD low only occur with clutch pedal switch or transmission safety switch closed. When operator selects 4WD or 2WD mode, actual shifting is carried out by electric motor mounted on the transfer case.
Electronic Shift Control Module
This module controls operation of transfer case, using inputs from 2WD/4WD selector, vehicle speed sensor, shift position sensor and transmission range sensor or clutch switch. Electronic shift control module is located in right kick panel. Module is equipped with a self-test capability.
If all conditions are correct, electronic control module will signal electric shift motor to shift gear positions. After shift takes place, module will read input from shift position sensor to determine if transfer case is in desired position. Control module will then illuminate push button and dash indicator light.
