Question about 2007 GMC Yukon Denali
We changed the transmission fluid in my 2007 Yukon Denali and now the transmission temp is running at about 160 degrees when driving on the highway. Is that running too hot? What could cause it to do this? Is there a restriction in the transmission coolant line? Is it going to be hard to fix or should I take it to the dealer. Will the dealer cover it under warranty? Thanks.
I you did it by yourself is better to tell the dealer that you truck has that problem dont tell them that you did that because you may have voided the warranty.
