This cancels and replaces 83-127 dated February, 1984 which should be destroyed. This issue corrects the PROM part number from 1226657 to 1226647.

Some comments of TCC hunting, particularly when operating with the cruise control engaged, have been received on some of the above mentioned vehicles.

To correct this condition, two (2) new PROMS have been released to raise the TCC engagement speed.
