Installation Notes and Tips

Confirm the transmission code and fitment notes before installation. Several applications are transmission-specific, including 4R70W, 4R75W, and AOD-E listings, and some vehicles only fit certain years or positions such as front or outer. Inspect the pump bore and sealing surface for wear, and replace the seal during transmission service to help maintain proper fluid control.
