Auxiliary Cooler

To change the transmission fluid Transmission Oil Cooler on a 4l60-e/4l65-e/4l70-e automatic transmission, first remove the grille assembly and put a drain pan under the vehicle. Relax each of the Transmission Oil Cooler lines from the Transmission Oil Cooler and then take out the Oil Cooler lines. After that, remove the 4 bolts holding the Transmission Oil Cooler to the radiator support and remove the Oil Cooler. First, put in the four bolts that hold the Oil Cooler to the radiator support and tighten them to 10 nm (89 inch lbs.). Attach the Oil Cooler lines to the Transmission Oil Cooler and make sure they are tightened with a torque of 23 nm (17 ft. Lbs.). After this, take out the drain pan and put the grille assembly back in place.

A 4l80-e/4l85-e automatic transmission requires starting the transmission fluid auxiliary cooler replacement process by taking off the grille assembly and breaking connections to the auxiliary cooler lines. Begin by disassembling the push clips securing the lines to the auxiliary cooler mounting bracket before manually elevating and supporting the vehicle. Begin the process by disconnecting the auxiliary cooler bracket's lower bolts and lowering the vehicle for access to remove all bracket bolts. Install the Transmission Oil Cooler into the vehicle and apply torque of 10 n.m (89 lb in) when installing the upper bolts to the Transmission Oil Cooler bracket. Reposition the vehicle to bolt the lower bracket to the Transmission Oil Cooler and finish the job with bolt torque set to 10 n.m (89 lb in). Lower the vehicle afterwards. After attaching the Transmission Oil Cooler lines to the auxiliary Transmission Oil Cooler connect them to the push clips in the mounting bracket before placing the grille assembly back.

First remove the grille assembly and put down a drain pan under the vehicle before replacing a 4l60-e/4l65-e automatic transmission's transmission fluid auxiliary cooler. Begin the fix by disconnecting the Transmission Oil Cooler lines from the auxiliary Transmission Oil Cooler then remove those Oil Cooler lines. Take out the auxiliary Transmission Oil Cooler by unscrewing its 4 mounting bolts which hold it to the radiator support. Secure your transmission auxiliary Oil Cooler to the radiator support through four bolts while applying 10 nm (89 inch lbs.) of torque. Replace the Oil Cooler lines on the auxiliary Transmission Oil Cooler unit while tightening them to 23 nm (17 ft. Lbs.). First, empty the drain pan and then replace the grille assembly in its proper position.

Replacing the transmission fluid auxiliary cooler on a 4l60-e/4l65-e/4l70-e automatic transmission requires initial disassembly of the grille assembly. A drain pan should be placed under the vehicle as technicians remove Transmission Oil Cooler lines from the auxiliary Transmission Oil Cooler unit. You must first take out the Oil Cooler lines that connect to the auxiliary cooler but keep the lines connected to the cooler. Then remove all 4 bolts which hold the auxiliary Transmission Oil Cooler to the radiator support before extracting the cooler itself. The installer should attach the Transmission Oil Cooler to the radiator support by using 4 bolts which need tightening to 10 nm (89 lb in). Connect the Oil Cooler lines to the auxiliary Transmission Oil Cooler and torque them to 23 nm (17 lb ft). Finish by removing the drain pan and reinstall the grille assembly.

For the 4l60-e/4l65-e, remove the grille assembly and place a drain pan under the lower part of the vehicle to replace the transmission fluid auxiliary cooler. Detach the Transmission Oil Cooler from the auxiliary Oil Cooler, and afterwards remove the Oil Cooler lines. The next step is to get rid of the 4 bolts and then take out the auxiliary Oil Cooler. Attach the Transmission Oil Cooler to the radiator support using the 4 bolts and ensure they are tightened to 10 nm (89 inch lbs.) also, remember to tighten the Oil Cooler lines to the auxiliary Oil Cooler so that they reach 23 nm (17 ft. Lbs.) after that, remove the drain pan and place back the grille assembly on your vehicle.

Start the repair process for a 4l80-e/4l85-e automatic transmission Transmission Oil Cooler by first removing the grille assembly. First disconnect the oil cooler lines then remove them from the push clips on the mounting bracket. Lift and stabilize your vehicle before removing all lower mounting bracket bolts from the oil cooler assembly. First lower the vehicle then choose the upper bolts off before extracting the oil cooler. Install the oil cooler into its position while you should tighten the upper bolts of the oil cooler bracket to a torque of 10 nm (89 lb in). Raise the vehicle to install the lower bolts onto the oil cooler bracket while tightening them to 10 nm (89 lb in). Connect the oil cooler lines to the oil cooler unit before attaching the lines to push clips in the mounting bracket while the vehicle remains in a lowered position. Finally, reinstall the grille assembly.

Start the replacement of a 4l60-e/4l65-e/4l70-e automatic Transmission Oil Cooler by removing the grille assembly before placing a drain pan underneath the vehicle. First disconnect the Transmission Oil Cooler lines from the auxiliary Oil Cooler before removing the Oil Cooler lines. The procedure involves first removing the 4 bolts which fasten the auxiliary Oil Cooler to the radiator support before taking the cooler out. The installation process requires you to mount the Oil Cooler onto the radiator support using four bolts with a torque of 10 n.m which is equivalent to 89 lb in. Tighten the Oil Cooler lines to the auxiliary Oil Cooler using 23 n.m torque (17 lb ft). After draining the reserve fluid place the drain pan aside before putting back the grille assembly.

Install the upper bolts into the oil cooler bracket and tighten them to 10 N.m (89 lb in).

First, remove the grille assembly.

Place a drain pan under the vehicle.

Begin by removing the grille assembly and disconnecting the 2 lines from the auxiliary cooler.

Begin by removing the grille assembly and disconnecting the 2 lines from the auxiliary cooler.

Place the oil cooler into the vehicle and install the upper bolts into the oil cooler bracket, tightening them to 10 Nm (89 inch lbs.).
