'08 Silverado won't move when put in reverse
I have an '08 silverado 1500 (2WD). a few days ago, when I was leaving for
work, I put my car into reverse, heard a loud sharp banging noise, and it
wouldn't move backwards. I shifted into drive and moved forward. Shifted
back into reverse and no movement. Gassing did nothing..When I put it in
park, it again made a loud bang. Tow truck driver helped me push it out of
garage. We tried it again, and it worked. I drove it in to the shop (about 5
miles). On the way there, it made a loud noise one time pulling away from a
light, in drive, but it drove fine. Last summer the shop re-filled my
transmission fluid and replaced the filter. They did not find any problems with
the transmission. I've been driving it for a couple of days now, without any
issues. Some friends have suggested checking rear differential fluid level.
I'm sure the shop did not check it. I just came here to ask if anybody had any
ideas before I start chasing down every possibility.
