Its either transmission related or transfer case, since I've ruled the shaft out. Unless I'm getting a weird engine surge which doesn't throw lights (doubtful)


Its not either of the differentials. Since the 6HP26 is getting a full ZF service next month I would hope that would alleviate. And of course, all the know it alls on the forums have already tempted me saying "OMG MERCON SP IS SAME THING" but I will use the Lifeguard6 for peace of mind - For a service that gets done less often than tire changes I am amazed at the amount of people who wouldn't stick to the transmission manufacturer recommended fluid.
