Installation
+Drive plate runout
CAUTION:
Do not allow any magnetic materials to contact the ring gear
teeth.
Maximum allowable runout:
Refer to EM section (ªInspectionº, CYLINDER
BLOCKº).
If this runout is out of specification, replace drive plate with
ring gear.
+When connecting torque converter to transmission, measure
distance ªAº to be certain that they are correctly assembled.
Distance ªAº:
Refer to SDS, AT-1210.
+Install converter to drive plate.
+After converter is installed to drive plate, rotate crank-
shaft several turns and check to be sure that transmis-
sion rotates freely without binding.
+Tighten bolts securing transmission.
