This new trans is plagued by the damn EPC solenoid shift problem when hot. The rebuilder said he never changed the EPC....wtf kind of builder is he......this issue is the number one problem of the 4T65E and he never changed it......Now he blames that my original solenoid is bad and wants to charge me to do an EPC even though I have a two year parts&labor unlimited mileage warranty.....again wtf....correct me if I'm wrong isnt the warranty cover the entire rebuild...?? Also if the rebuilder was stupid enough to not replace the number one defect of these transmissions why do I have to pay for his stupidity and bad judgement on how he built it..??....Hello BBB...!!!
