This cancels and replaces 83-135 dated April, 1984 which should be destroyed. This copy identifies engine and code usage.
Please be advised that service PROMs have been released for the 1983 Celebritys and Citations to revise the TCC re-engage points to
require significantly less throttle for re-engagement. This will eliminate the continual disengage/re-engage on grades, particularly when
operating under cruise control. New PROMs are as follows:
P/N 1226647 replaces P/N 1226439 for 2.84 axle
P/N 1226648 replaces P/N 1226441 for 2.39 axle
