OK so my buddies Dodge the one I was going to buy. I'm on the fence . It slips once in awhile if you start it up and just go. When its freezing outside and the truck has sat awhile. My buddy says its done it a few times In 6 months and he thinks its because 15k miles ago his dad had a trans flush and used bg universal fluid. His dad also thinks so. If the truck sits for a minute it wont do it only when you just start it and go. Fluid level is good . Filter isn't much older than fluid. It did it last year when the fluid was done and then didn't do it again till this winter. Anyone have any experience with bg . Maybe it's the cause? I'm not sure but I don't think it's licensed atf+4 but says it will work for atf+4 kind of confused. Any help is appreciated
