7B-64 AUTOMATIC TRANSMISSION (3 A/T)
1. Stator inner race
(should turn freely clockwise)
TORQUE CONVERTER DIAGNOSIS
STATOR ASSEMBLY FREEWHEELS
If the stator roller clutch becomes ineffective, the stator assembly
freewheels at all times in both directions. With this condition, the
vehicle tends to have poor acceleration from a standstill. If poor ac-
celeration problems are noted, what to be checked first are that the
exhaust system is not blocked, the engine is running properly and
the transmission is in 1st gear when starting out.
STATOR ASSEMBLY REMAINS LOCKED UP
If the stator assembly remains locked up at all times, the engine
rpm and vehicle speed will tend to be limited or restricted at high
speeds. The vehicle performance when accelerating from a stand-
still will be normal. Engine overheating may be noted. Visual ex-
amination of the converter may reveal a blue color from the
overheating that will result.
Under above conditions, if the converter has been removed from
the transmission, the stator roller clutch can be checked by insert-
ing a finger into the splined inner race of the roller clutch and trying
to turn the race in both directions.
The inner race should turn freely clockwise, but be heavy to turn
counterclockwise.
NOTE:
D Converter placed with its flange upright does not fit for this
inspection.
D For proper checking, position converter with its flange hori-
zontal.
D Turn stator inner race clockwise as quickly as possible with
finger, then turn reversely at the same speed and feel differ-
ence of enertia.
DO NOT REPLACE CONVERTER FOR THE FOLLOWING
CONDITIONS:
1) The fluid has an odor, is discolored, and there is no evidence of
metal particles. There is no indication of existence of internal
damage, or oil pump damage. Dump out as much fluid as pos-
sible from the converter and replace only the oil pump screen
in the pan.
2) A small amount of wear (sometimes referred to as fretting wear)
appears on the hub where the oil pump drive gear is located. A
certain amount of such wear is normal for both the hub and oil
pump gear. Neither the converter nor the oil pump assembly
should be replaced.
