SUBJECT:
LOSS OF DRIVE AND REVERSE - THM440-T4
MODELS AFFECTED: 1985 - 1986 DE VILLE/FLEETWOOD
Some 1985 and 1986 Cadillacs equipped with a THM440-T4 transaxle may experience either an intermittent or complete loss of drive in all forward and
reverse ranges. This condition can be caused by input sprag clutch disengagement or "pop-out" (refer to the 1985 De Ville/Fleetwood Service
Information Manual, Section 440-T4, Figure 34, items 650 to 654). Transaxle main line pressures may be uneffected.
