Trooper (2 Door) V6-3165cc 3.2L DOHC (6VD1) (1992)
Band Control Solenoid Valve: All Technical Service Bulletins
A/T - Clunking Noise on 3-2 Downshift
4L30-E A/T DOWNSHIFT CLUNK WHEN BRAKING
1990-91 Trooper II (KT), 1992-93 Trooper (UX) and 1991-93 Rodeo (UC) models equipped with 4L30-E automatic transmission with A/T assembly
serial number before 4006228.
A/T serial number is stamped on the identification plate located on the left side of the transmission case, above the mode switch.
Affected vehicles may experience a clunking noise during the 3rd to 2nd gear downshift when braking. The noise is caused by poor band apply solenoid
operation. Installing a new, improved band apply solenoid (see "Parts Information" section of this Service Bulletin) will eliminate this condition.
FLAT RATE MANUAL UPDATE INFORMATION
Use the existing labor operation. See illustration.
If a clunking noise is heard during the 3rd to 2nd gear downshift when braking, replace the band apply solenoid (using parts listed in the "Parts
Information" section of this Service Bulletin), following the procedures in the appropriate Workshop Manual.
