About 5 yrs-ish. this issue has been about the last 5-6 months.

@AH64ID you got any thoughts on this? Today, I was able to get it to do it climbing a 3%, 5th gear, 60mph, empty, no trailer.. "Ding! See Dealer now" 5 secs later rpms drop and drop.. downshift, try to keep pushing up the hills as there's nowhere to pull over.. this goes on for about 20 secs, then it picks up like nothing happened..

LOL IDK what to tell you; I'm 2:2 on G56 GRO

Yeah, I wished it would give me a code, or be a little more explanatory, but that's too much to ask for, I'm sure. lol Prolly one of those 'hidden, dealer only' codes.

You shouldn't in the NV4500. My old 4500 with Valair 3650 DD didn't either. Both the MC and the Crew Cab (G56 in both) have insane gear rollover noise. Sitting idle, in neutral, and under load, sub 1500rpm. The MC has a Valair 3600 DD and the CC has a SB3600DD. The MC has 150k on it, the CC has 295k. Put the same style clutch in my old 2004 5600 and no rollover noise; a quick search on googly shows I'm definitely not the only one. It's weird.

I have those same headset in a desk drawer; the best place for 'em. 100% agree, they're not loud enough, and they pick up everything, mic-wise.

the noise I'm referring to isn't the steel disc. it's the gear-rollover of the G56, that the 5600/4500 doesn't suffer from. This is caused by the stock DMF of the G56 being replaced.

eeeew.. I do not envy that task..

The Sony is android-based. IDGAF much anymore about what brand I use, provided it functions as intended with my desired operational bells. BTW, Kenwood is really JVC now.. Also, the Sony has separate BT volume settings, so I can have the radio at, say, volume 20, and if I take a call, the BT is at volume 40, or whatever I set it to. Side Note: I used to be a MECP-Certified Master Installer for mobile electronics (not that THAT means much, I'm sure)

OE clutch? Sure, it's quiet. Put a DD in it, and it's a different animal when the stock flywheel is replaced.

160k miles on it. G56, RaceMe Tuner, deleted. Truck has newish Bosch injectors (OE), 5" exhaust, stock airbox, deleted egr/dpf, etc. Recently, it's developed this issue of falling on it's face when hooked up to something (dump trailer, hay wagon, etc). It does it empty, or not. I have Alfa OBD, and hooked up, and I see the following: No codes that I find. When it falls on it's face, it dings and I get the 'see dealer now' message.. After about 5 secs, it picks up where it left off and drives normal.. then it may/may not do it again.. Fuel filter changed, newish in-tank pump.. crap, wrong section of forum..

I installed a Sony 2din. It has Carplay, and Android Auto, B/U cam functionality; works great, and was cheap AF. like $200.

Downside to the G56 is noise, IMO.

This ended up being the pump.. thanks!

It's all OE. Stock gear box, etc. Stock size tires, MAYBE 265s at biggest. The fluid is slightly dark looking in the res, but not burnt/too dark. it's pretty red to the touch. Steering is (guessing on memory) 3ish turns, lock/lock. Truck has about 230-240k on it.

So I tried your method on purging.. I only got one tire off ground, worked it back/forth about 20 times while owner watched the fluid.. no bubbles.. then I started the engine with one tire off ground.. turned steering wheel with one finger.. great! put the tire on the ground? can't turn it.... Pick the other tire up, turns steering with one finger.. put it on the ground, no turn... I didn't get to pull the pump lines/fittings off, because it started raining.. Thoughts? think it's the pump? brakes felt normal/fine.

Yeah, I went through this same issue with my 07.5 (factory no-fogs). I added, and had to turn the signal on twice (on, save, off, save, on, save) before they started working.

Purge it, by turning the wheel back/forth while running? Or is there another trick? Only thing I can think of is crack a fitting, but that'll make a mess for sure lol I still need to find the source of the leak, regardless, so I'll try to do that tomorrow. thanks!

I'll go back out this weekend, and pull that apart first. Much appreciated @Dieselfuture

Went out to a friend's house last weekend to look at his truck for him. a month or so ago, I put a new steering stab (oem) and sway bar end-links on. shortly after, he started complaining about super hard steering when slow, or backing up... So I went out there and disconnected the stabilizer, for SnGs.. No change. Power steering pump is leaking, but had plenty of fluid in it. Hydra brakes work fine. Just cannot hardly turn it sitting still.. I don't wanna throw parts at it (pump or steer gear) without knowing pretty sure what is the issue. Any thoughts on this are greatly appreciated.. Pump doesn't whine/groan/nothing..

SOMEHOW, fuse 20/21 in the TIPM were pulled (they are joined in a fuse carrier) and were somehow disconnected from the circuit. The U0151 code isn't appearing now. But I still get a long crank, and (most times) need to remote lock/unlock to get the truck to start; otherwise, it just cranks/no start.. Man, the bugs/gremlins you get when a truck sits for extended periods of time.. LOL Thanks, Michael! Rick
