Question about 2004 GMC Envoy
Thanks Pyrhyc, I recently had the transmission flush and the oil changed at Jiffy Lube. Is it possible that the wiring to these sending units may have been disturbed during that service? Are the sending units close to either of the areas in question?
With the tranny flush, yes. It's possible that they may have knocked the connection loose or broke it at the sending unit. The unit is usually located on the side near the bottom ot the tranny. With the oil change I'm going to say no. The oil sending unit is generally located on the driver side, center of the engine block near or under the exhaust manifold, or on the front of the block towards the top. Unless they moved them on me, it shouldn't be anywhere close to the drain plug on the oil pan, and there no way that they should get near the oil sending unit when changing the oil, unless the sending unit is near the oil filter, and GMC generally doesn't put the two near each other for this reason. Just thought of something. Are the gages individually replaceable, or are they all built into one display unit?
