I have on 01 chevy silverado 1500 2wd. it has the 5.3 and it does show the g80 code in glove box so i assume it is the right glove box (my truck is a rebuilt). I had the trans rebuilt thinking it may be the problem and it was time for it anyway i think (230k). has the 4l60. now, i am a one wheel wonder. anytime there is wet pavement or i get in gravel I am pretty much stuck. only one wheel has any power. and of course the awful grinding and clunking. If i am going downhill and just let off the gas and let it coast, then when i get back on the gas i have 0 power. It's like something in the rear just doesn't go together but i can hold the brakes a bit and it will get power again, with a loud thud of course. Put it in neutral, same story. It shouldn't catch, just coast but it clunks and tried to catch. So i am assuming again that it had to be the rear and I have a Grenade -80. The truck needs to last me another 2-3 years until I get out of nursing school and buy a new one and I can't stand the fact of replacing junk with junk and that seems to be the case with the g80. I called one of the best mechs. around here and he said if i brought him the parts that he would charge 150 to swap the carrier. I just want to make sure I get all of the parts first before I take it to him and hold up a spot in his garage waiting for parts. Do you all think it's just the carrier or is it something else or something else plus more (R&P too). here is what from the research I have done is what I need. Please let me know something and thanks in advance!

Install kit:
Is this all the bearings/seals/shims i need?

cant help you as far as what you need but when you get ready to buy check out rons machine shop for parts.. seems to have a good rep around here and ill be buying through them when i rebuild mine

 

Pretty sure that's it.

+1 For Ron's machine services!

 

yeah just called Ron and got the tru trac and a master install kit for $490 shipped or a 4.10 or 3.73 gear master install and carrier for 600 shipped. Should I got ahead and replace the R&P or just see how it looks in there first?

 

I'd go ahead and do a gear swap while you are in there. Odds are that the Grenade 80 chewed up some of the teeth on the ring n pinion. Plus if you are going to be taking everything out, why not go ahead and upgrade while you are in there so you aren't paying for labor twice.

 

You ned to find out what the problem is before you order parts IMO....
