REVERSE LOCKOU T RELA YSee sectio n 2 3

Description

At a vehicle speed of 19 mph (30 km/h) or more, a signal from the vehicle speed sensor (VSS) activates the reverse lockout

solenoid, which causes the select lock pin to extend. As a result, the interlock cannot rotate to the reverse shift piece mak-

ing it impossible to select reverse gear.

At a vehicle speed of 16 mph (25 km/h) or less, the signal from the VSS is interrupted which turns off the reverse lockout

solenoid. The select lock return spring pulls the select lock pin back, enabling the interlock to move freely so that reverse

gear can be selected.ProCarManuals.com

Solenoid Test

1. Disconnect the 3P connector of the reverse lockout

solenoid.

2. Measure the resistance between No. 1 and No. 3

terminals.

If the resistance is not within the standard, replace

the reverse lockout solenoid.

3. Test reverse lockout solenoid operation by connec-

tor battery power to the No. 1 terminal and ground

to the No. 3 terminal. A clicking sound should be

heard.

4. If the reverse lockout solenoid no clicking sound is

heard, replace it.
Solenoid Replacement

1. Disconnect the 3P connector.

2. Remove the reverse lockout solenoid from the trans-

mission.

3. Remove the select lock pin and select lock return

spring.

4. Install the reverse lockout solenoid in the reverse

order of removal.ProCarManuals.com
