1995 JEEP CHEROKEE ECU

(99) Install retaining clamp for wire harness and
throttle cable (Fig. 69).
(100) Install torque converter.
(101) Verify that converter is seated by measuring
distance between converter housing flange and one of
the converter mounting pads (Fig. 70). Use straight-
edge and vernier calipers to measure distance. On
6-cyl. transmissions, distance should be 16.5 mm
(0.650 in.).
(102) Secure converter in transmission with
C-clamp or metal strapping. Do this before mounting
transmission on jack or moving transmission under
vehicle.(103) Install lower half of transmission fill tube (in-
stall upper half after transmission is in vehicle).
CAUTION: The transmission cooler and lines must
be reverse flushed if overhaul corrected a malfunc-
tion that generated sludge, metal particles, or
clutch friction material. The torque converter should
also be replaced if contaminated by the same mal-
function. Debris and residue not flushed from the
cooler and lines will flow back into the transmission
and converter. The result will be a repeat failure and
shop comeback.
