Wandering if anyone has had a problem with pulling a RV with the 323 rear end gear ratio in a 1500 Sierra Crew Cab?

What's the weight of the RV? Going over mountains?

 

 

The weight will approx. 7500, and will not be going into mountains.

With the 3.23 gears I would guess that you've got the 4.8L engine. This combo has a weight limit of 6300lbs in the documentation I can find.

Good luck with that, I hope it's down hill to your destination.

 

 

I have the 5.3 engine, and according to the code in glove box, I have the 3.23 gears.

With the 5.3 and 3.23's, I find a max trailer weight of 6800lbs.

 

Do you have a transmission oil cooler?

Actual weight or Gross weight?

 

What I am getting at is; That you may still be able to tow the trailer, as long you dont load it down.

No offense man, but no way in hell you can tow a 7500 pound RV with 3.23 gears. Even with a cooler, your trans will be toast in short order. WAY too much weight for that configuration.

 

4600 pounds is MAX capacity according to the GM website with 3.23 gears and a 4.8 V8 (6600 pounds MAX with 3.42 gears and a 5.3 V8)

 

You need a different truck that is designed for towing weight that heavy.

Just a suggestion.. but depending on what your plans are (weekend adventure?) it'll probably be a lot cheaper to rent a 2500HD for this trip than it would be if you fry your tranny, wear your brakes and any other over loaded components that will decrease the life of your vehicle.

To give you an example look below at my sig pic.I have a K2500,454,4:56 gears towing a 7,500lb.(total weight) toy hauler full of dirtbikes.I also have a K1500 'Burb and would in no way tow the toy hauler with it.You need something bigger.

No Way, No How. You also have to remember suspension and brakes. It's not all about getting it moving. You also have to keep it on the road and sometimes stop. That truck is not designed to do any of those things with that much weight behind it.

I would never tow with anything over 3,000lbs with 3.23 again.

 

I once towed a uhaul car trailer with a regular cab dodge dakota 2wd on top of it with my truck that is in my sig from one side of town to another(about 40 miles).

 

I kid you not that I-10 in El Paso is pretty much flat. My truck had a hell of a time towing that thing. I kept it in third and it would shift down to 2nd.

 

the 5.3 needs 3.73 minimum 4.10 preferably to tow anything over 3,000 lbs.

I can't believe we haven't got the "just keep it in 3rd and keep an eye on your temps., you'll be fine." yet.

 

 

'Cause we dont want this guy to ruin his truck, but he can keep it in 3rd and watch the temp skyrocket and then BOOM there goes the tranny.

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
