SERVICE ACTION
1984-87 Models built before August 4, 1986 (Julian Date 216):
If a vehicle equipped with a THM 200C transmission has a harsh PARK/NEUTRAL to DRIVE engagement, install the Neutral Drive Shift
Package.
1987 Models built on or after August 4, 1986 (Julian Date 216):
Models built after implementation of the feed/bleed system can be serviced with individual parts.
IMPORTANT
When servicing the forward clutch, select the correct backing plate (627). Backing plate selection affects piston travel, shift feel and clutch
durability.
Backing plate selection (clutch fully assembled):
Apply an evenly distributed load in the direction indicated in Figure 3, to remove slack from the clutch assembly. Use 20 lbs (9kg) of pressure against
the backing plate -- excessive pressure will cause an inaccurate measurement. With the clutch assembly compressed, use a feeler gage to measure the
distance between the backing plate and snap ring. Correct backing plate travel is 0.7 mm-1.5 mm (0.028"-0.059").
