Install Guide - AW55-50 - Aisin (Automatic Transmission)



• Scan and record any codes stored in vehicle computer and resolve all engine codes before replacing transmission.
• On Nissan Mixima, Altima, and Quest applications (T530503, T530512, T530513, T530514, T530517), a new cooler has been installed by the remanufacturer.
• On Chevy Equinox and Pontiac Torrent applications (T530511, T530515, T530518, T530522), carefully inspect the radiator and, if damaged, replace radiator and hot flush or replace cooler lines.
• For all other applications, do not flush cooler.
• Inspect flex plate closely and completely for cracks or any damage - replace if necessary.
• Inspect crank pilot bore for wear and apply a small amount of grease into bore to aid with torque converter installation.
• Verify both dowel pins are clean, installed properly, and are in good condition.
• Compare replacement and original transmission and torque converter before installation.
• Check torque converter bolt length; too long of a bolt will damage the torque converter.
• Verify torque converter is properly and completely installed onto output shaft.
• Do not tighten the bell housing with force; torque conveter may have shifted during installation.
• Inspect and install the Park-Neutral Position (PNP) Switch, Input Speed Sensor (ISS), and Output Speed Sensor (OSS).
• Fill transmission with purchased synthetic or OEM-approved fluid.


Prior to installation of the replacement transmission, scan vehicle for engine and transmission codes, record all codes, and resolve all engine codes prior to transmission replacement. If you are not able to perform a scan, take the vehicle to a dealership. If any ABS or Speed Sensor codes are found, these problems must be resolved before transmission replacement.

Inspect the transmission wiring harness for damaged wires or connectors. Verify proper function of the entire electrical system including the battery, alternator, and, most importantly, the vehicle grounds.

This is an electronically-controlled transmission with a complex shift adapt system. The following is very important to understand and perform correctly. Failure to do so may cause damage to the transmission and/or result in transmission performance problems.

Schedule a TCM relearn with your local dealership. Aftermarket software is vehicle year specific, therefore expensive and with mixed results. You may want to build the cost of a TCM relearn into your estimate. Proof of relearn will be required for your warranty.

It may be necessary to drive the vehicle up to 400 miles for the shift adapts to be completed. Inform your customer of the additional mileage on the odometer.
