3.42 to 4.10


Recommended Posts

I'm not happy trailering with this truck.  On hilly backroads I'm either redlining in 2nd or dieing in 3rd.  So I thought changing the rear might help.  I spoke to a Chevy service rep who told me I would have to change the gears in the front as well due to 4wd, and that this would push the cost towards ?k.  

Does this sound right?  

Is there a better way to go?

The trailer weights >5,000 lb, and the truck is as described in sig.  

Thanks.

The problem with the old TBI's is that the redline is 4000rpm.  4.10 gears is the best bang for the buck, especially for towing, but ? is crazy.  The gears itself can be bought for ?.  You'd need two sets-one front diff and one rear diff.  Installation is a pain in the @!#.  I highly recommend hiring someone to do it.  I would say ? is close.  

www.summitracing.com has Richmond gears for ?.   Most big service centers can do it.  2 grand is nuts in my opinion.

? is way too much for a gear swap!!  Try to get hold of kaspar139, via messenger.  He's done a ton of shopping and price checking on gear swapping lately.  I'm sure he'd share what prices he's found.  I think pastmaster is more in the ballpark-

This is just a thought, but if you aren't towing all the time and your running stock size tires then maybe 3.73 gears would be a good comprimise.  Otherwise I'd reccommend 4.10's...  You'll be turning alot more rpm's though, especially at highway speeds!!!

Go with the 4.10's. I had 3.73's and they were adequate, but the 4.10's are better. If you're running 265's it might not be too bad on the gas mileage. I'm running about 2200 rpm's at 70 mph with the 265 TA's. 2k for a gear swap does sound pretty high.

    • Thanks for posting, I'm sure it will help someone
    • New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended? 
    • So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.  
    • Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.
    • That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
