COMPLAINT:
There has been a change made to the valve body spacer plate and the 1-2 accumulator housing on 1987 and 1988 THM 200-4R transmissions (See Figure 2 and Figure 3).This change affects the following models: 1987 or 1988 CCF, CHF, CRF, CYF, CZF, KCF, KJF, KTF.
CAUSE:
The l-2 accumulator will now function as a reverse accumulator also, to soften the reverse garage shift engagement.
CORRECTION:
(1) VALVE BODY SPACER PLATE - The new spacer plate has a round hole instead of the previous rectangular hole, as shown in Figure 2.
(2) VALVE BODY GASKETS - Redesigned to accommodate the new spacer plate and accumulator housing.
(3) ACCUMULATOR PLATE GASKET - Redesigned to accommodate the new accumulator housing and checkball assembly.
(4) l-2 ACCUMULATOR HOUSING - The new accumulator housing contains revised passages and a checkball and sleeve assembly as shown in Figure 3.
INTERCHANGEABILITY:
Can be used on previous models as long as "ALL" of the redesigned parts are used, and will soften the reverse garage shift engagement.
