A/T - Occasional Long 1-2 Shift When Cold
Number 85-7-8A Date 3/85Subject: OCCASIONAL LONG 1-2 SHIFT WHEN COLDSOME 1984 AND EARLY 1985 THM 200-C TRANSMISSIONS
FIGURE 1 - TYPICAL 200C SPACER PLATE:
Some 1984 thru early 1985 THM 200-C transmissions may experience an occasional long 1-2 shift when cold.. To repair this condition, a new spacer plate went into production on September 24, 1984 (Julian date 268).
When servicing any 1984 thru early 1985 THM 200-C transmission built before the above Julian date, remove the valve body spacer plate. Drill the 2nd and 3rd clutch exhaust orifice out to 3.57 mm (9/64") (Refer to Illustration 1 below). Using a 6.3 mm (1/4") drill bit, hand chamfer both sides of the hole, slightly, to remove burrs and rough edges.
