All vehicles
-
NOTE: Failure to flush the transmission fluid cooler and transmission fluid cooler tubes can result in metallic contamination of the transmission.
If installing a new, remanufactured or overhauled transmission, clean and backflush the transmission fluid cooler tubes to prevent repeat repairs. For additional information, refer to TRANSMISSION FLUID COOLER BACKFLUSHING AND CLEANING .
-
NOTE: Failure to install a new auxiliary transmission fluid cooler can result in metallic contamination of the transmission.
If installing a new, remanufactured or overhauled transmission install a new auxiliary transmission fluid cooler if equipped.
-
NOTE: Failure to clean the Power Take-Off (PTO) can result in metallic contamination of the transmission.
For vehicles equipped with a Power Take-Off (PTO) assembly, prior to installing the transmission, flush and clean the PTO assembly to remove any foreign material. Failure to remove foreign material from the PTO assembly may result in subsequent transmission concerns.
- Inspect the back of the engine to be sure both dowel pins are in the engine. If the dowel pins are not in the engine, install new dowel pins as needed. If installing the same transmission that was removed, remove the dowel pins from the transmission and install them in the engine. Rotate the flexplate to align the 2 slots at the 6 o'clock position.
-
NOTE: Prior to installation of the transmission, lubricate the torque converter pilot hub or damage to the torque converter or the engine crankshaft can occur.
Lubricate the torque converter pilot hub with multi-purpose grease and align the paint dot on the torque converter in the 12 o'clock position.
- If the Torque Converter Retainer has not been installed during the assembly of the transmission, install the Torque Converter Retainer to hold the torque converter in place while moving and positioning the transmission in place. Once the transmission is in place, remove the Torque Converter Retainer.
