Check
1. NOTE: Front pump support may remain in front pump support and gear during this test.
Position the front pump support with the splines up.
2. Mount the torque converter on the front pump support with the splines on the one- way clutch
inner race, engaging the mating splines of the front pump support.

Install the reverse band.
9. NOTE: The planetary assembly and planetary gear support cannot be installed unless the notch
cut in the planetary gear support is aligned with the overdrive band anchor pin.
NOTE: The top of the planetary gear support must be below the snap ring groove.
Install the planetary assembly and planetary gear support as a unit. zRotate the output shaft to fully seat the planetary assembly.
10. NOTE: The planet support spring must be compressed and installed below the snap ring
groove. When the planet support spring is installed correctly both ends of the spring will be
visible.
Install the case to the planet support spring located at the 1 o'clock position.

INSTALLATION
Transmission
1. CAUTION: During this move, to avoid damage, do not allow the transmission to get
into a nose- down position as this will cause the torque converter to move forward and
disengage from the pump gear. The converter housing is piloted into position by dowels
in the rear of the engine block. The torque converter must rest squarely against the
flexplate. This indicates that the converter pilot is not binding in the engine crankshaft.
Position and secure the transmission on the high- lift transmission jack.
2. CAUTION: Make sure the torque converter is fully seated in the transmission before
positioning the transmission to the engine.
Using the special tool, install the transmission to the engine.
zAlign the orange balancing marks on the converter stud and the flexplate bolt hole. 3. Reconnect the harness. SECTION 307-

DIAGNOSIS AND TESTING
Transmission Cooling
Inspection and Verification
WARNING: Never remove the radiator cap under any conditions while the engine is
operating. Failure to follow these instructions could result in personal injury and/or damage to
the cooling system or engine. To avoid having scalding hot coolant or steam blow out of the
radiator, use extreme care when removing the radiator cap from a hot radiator. Wait until the
engine has cooled, then wrap a thick cloth around the radiator cap and turn it slowly to the first
stop. Step back while the pressure is released from the cooling system. When you are certain
all the pressure has been released, press down on the radiator cap (with a cloth), turn and
remove.
The transmission fluid cooler is integral to the radiator (8005). Whenever leaks or damage to the
radiator are found, install an entire new radiator. For additional information, refer to Section 303 - 03A or
Section 303 - 03B .
