So last week I posted about my truck being in limp mode and showing codes pertaining to high dpf filter but suggesting it may b electrical in nature... It ended up being my wiring harness under the drivers side of the truck had been chewed by an animal, possibly my dog.. I first wanted to thank everyone for the replies and help... Now my new found problem is that my transmission cooling hoses are leaking close to the radiator. Is this something I can tackle cheaply and relatively easy? Thanks again...
