Removal

1. 1
   Remove the battery tray.
   Refer to: Battery Compartment (414-01 Battery, Mounting and Cables, Removal and Installation).
2. 2
   Remove the nut and disconnect the ground cable terminal from the transmission fluid warmer tube stud.

   

3. 3
   Remove the bolt, stud and the transmission fluid warmer tube.

   

4. 4
   Inspect the transmission to make sure the fluid tube seal and the backup ring were removed with the fluid tube and are not stuck in the transmission. If the fluid tube seal or the backup ring is stuck in the transmission, remove the seal and the backup ring.

   

5. 5
   Fully loosen the fitting, remove the bolt and remove the bypass valve tube from the warmer to the transmission fluid cooler.

   

6. 6
   Inspect the transmission fluid warmer to make sure the transmission fluid tube seals and the backup rings were removed with the transmission fluid tubes and are not stuck in the transmission fluid warmer. If the transmission fluid tube seals or the backup rings are stuck in the transmission fluid warmer, remove the seals and the backup rings.

   

7. 7
   Pinch off the coolant hoses and disconnect the quick-connect coolant hose couplings from the transmission fluid warmer.
   Use the general equipment: Hose clamp(s)

   

8. 8
   Remove the bolts, nut and the transmission fluid warmer.
