TROUBLE SHOOTING GUIDE
The following data is presented as an aid to locating the source of difficulty in a malfunctioning unit. It is
necessary to consider the torque converter charging pump, transmission, oil cooler and connecting oil lines as
a complete system when running down the source of trouble since the proper operation of any unit therein
depends greatly on the condition and operation of the others. By studying the principles of operation together
with data in this section, it may be possible to correct any malfunction which may occur in the system.
TROUBLE SHOOTING PROCEDURE BASICALLY CONSISTS OF TWO CLASSIFICATIONS: MECHANICAL AND
HYDRAULIC.
MECHANICAL CHECKS
Prior to checking any part of the system from a hydraulic standpoint, the following mechanical checks should
be made.
1. A check should be made to be sure all control lever linkage is properly connected and adjusted at all
connecting points.
2. Check shift levers and rods for binding or restrictions in travel that would prevent full engagement. Shift
levers by hand at transmission case, if full engagement cannot be obtained, difficulty may be in control cover and
valve assembly.
HYDRAULIC CHECKS
Before checking on the torque converter, transmission and allied hydraulic systems for pressures and rate
of oil flow, it is essential that the following preliminary checks be made.
1. Check oil level in transmission. This should be done with oil temperatures of 180-200F. [82,2-93,3C.].
DO NOT ATTEMPT THESE CHECKS WITH COLD OIL. To bring the oil temperature to this specification it is
necessary to either work the machine or "stall" out the converter. Where the former means is impractical, the
latter means should be employed as follows:
Engage shift levers in forward and high speed and apply brakes. Accelerate engine half to three-quarter throttle,
Hold stall until desired converter outlet temperature is reached. CAUTION: FULL THROTTLE STALL SPEEDS
FOR AN EXCESSIVE LENGTH OF TIME WILL OVERHEAT THE CONVERTER.
