SERVICE INFORMATION
On some affected vehicles, when driving at engine speeds 2000-3000 rpm with light throttle, a rattling noise may be heard from the gear selector lever
area. The noise may be caused by the A/T reverse clutch plates rattling against the main transmission case.
To eliminate the noise, install the new, improved reverse clutch plates listed in the "Parts Information" section of this Service Bulletin.
SERVICE PROCEDURE
1.
Confirm source of rattling noise by test driving vehicle as follows:
a.
Start the engine and allow to idle until it reaches normal operating temperature.
b.
Drive at engine speeds between 1000-3000 rpm in each forward gear. If the noise is caused by reverse clutch plates, an irregular rattling
noise will be heard at about 2000 rpm when applying light throttle.
c.
With the vehicle raised on a hoist, listen for a rattling noise about 1" to 2" behind the front cooler line while running engine at 2000 rpm in
any forward gear.
