SERVICE ACTION:
1984-1987 MODELS BUILT BEFORE AUGUST 4, 1986 (JULIAN DATE 216):
If a vehicle equipped with a THM 200C transmission listed in SERVICE PARTS INFORMATION 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.
Figure 3
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 (9 kg) 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").
