Question about GMC Cars & Trucks
Either both bulbs are bad(I've seen it before) or your
dimmer/headlight switch is bad. If you can without pulling the bulb, pull plug from the light. If it's a 4 lamp system pull the low beam. Do this on the left side as the right feeds from the left. With a 12v test light, check for power. (with lo beam on) if you have
power, change the lamp, if you don't it's most likly
the dimmer switch at the steering collum.
Hope this helps Good luck

On most vehicles the transmission information is inbeded the VIN # or vehicle identifation number . Unfortinatly on GMC and CHEVY its not . It is stamped on the passangers side of the transmission at the rear of the oil pan just above the pan gasket you will likely have to clean it off to read it it will be a 9 digit # with letters being in it . The most common transmission for an automatic is the 4L60-E If the forth digit is D thats what it is . As far as the leak goes you need to deturman where its leaking from the pan gasket or the rear oil seal or is it comeing from in front . Transmission do not normanly leak so make sure that its not engine oil you are seeing that is being blowen back witch is much more comon . Transmission fluid is red and smells differant then engine oil and is thinner . Check the oil level on the transmission see if its red and dose it smell burnt if so it will be more black witch is vary bad . Do you have any shifting problems .Also check your engine oil to compare the 2 oils . In a nut shell its your vehicle and your the olny one that actully look at it and looking saves money and blindly replaceing parts costs a lot and rearly fixes the problem
