Engine Mechanical problem
1999 GMC Sierra V8 Four Wheel Drive Automatic 165000 miles
My truck is a half ton with the Z71 off road package, it has the 5.3L engine and 4L60E Transmission, I've put the last 83k miles on the truck with few problems and my transmission lost reverse, second, and fourth gears, no problem got the tranny rebuilt with a new sunshell and whatever else the guy thought it needed, or so I thought, he gave me another tranny off the shelf that supposedly had been rebuilt but 200 miles after I get it back it starts making noise in first and reverse and he says its a planetary bearing, a fluke he says and he will make it right.
That being said I'm nursing it out to him because it seems fine in every other gear but those two, so half way there my truck dies out like its running out of gas or something, I put two five gallon cans worth of premium fuel and still it will only run sporadically at best and to keep it running you have to keep the gas pedal at a certain spot maintaining around 2k rmp to keep it moving, otherwise it starts acting like its sucking only air and going to die out and I'm wondering if something being wrong with the trans would affect how the enging runs, and I am wondering first off did this guy do something to my truck or is this a coincidence because I'm sure he has the computer and software to mess with settings which I don't and this is the first time I've used him to do auto work for me? Secondly since I know its getting some gas I am assuming the fuel pump is trying to work, so I am next putting a new fuel filter on it and then going to check the fuel pressure to see if its good, and if it isn't ill assume it must be the pump, but if it is good then what next?
Thanks for any help, info, and/or advice with this problem.
