2009 GMC Yukon Transmission Oil Cooler Parts and Q&A

• Q: How to replace the Transmission Oil Cooler on a 4L60-E/4L65-E/4L70-E automatic transmission on 2009 GMC Yukon?

  A: Start with front grill assembly removal as the first step for replacing a 4l60-e/4l65-e/4l70-e automatic transmission transmission fluid auxiliary cooler. A drain pan should sit underneath the vehicle before you disconnect the Transmission Oil Cooler lines that attach to the auxiliary cooler. The first step requires separating the auxiliary oil cooler bolts and push pins; afterwards you can remove the component from the vehicle. Installation requires positioning the new auxiliary oil cooler on the radiator brace then bolting and securing it with push pins before tightening the bolts to 12 nm (9 lb ft). You should attach Transmission Oil Cooler lines to the auxiliary cooler before reinstalling the front grill assembly.
