What did I do with my GMC Yukon cel?
The CEL disappeared after a few ignition cycles. A few TSBs, #PIP4304A and #PIP4184B, and 09-07-30-004A, appear to be on point. I’m not that familiar with how automatic transmissions work, but the TSBs appear to involve disassembly of the transmission and the possible replacement of valves, control modules, etc., which sounds fairly involved.
