91761Duramax

dumb question but what is a load?

Thank You Chevy1925 it was 2 water outlet seals that was causing the leak. I had to take it to a shop. Labor was expensive but less then a head gasket. The leak was in the upper and lower coolant tube

How difficult is it to do a transmission oil change? My only worry is is drooping the transmission to replace the internal filter.

Unfortunately I wasted my $ on the AEM transmission already couple months ago when I had my old LLY. Thank you for everyone for the input

Doing full transmission oil change next pay check with 2 filters also will be Adding AFE transmission pan

Truck back normal NSUB did the trick, my neighbor ran his expensive scanner no codes were thrown.

Co Worker recommended Rancho Transmission, only 3 miles from work, they ran the snap on scan tool and t it was not sending a signal to the scanner. Guy told me it maybe electrical and take it to the dealership. Drove it home and it ran through all 5 gears with no problem? This time when I had it on drive nothing was underline until I had it on P. NSUB should be coming in tomorrow. Will switch that out 1st. I wonder if moisture got into the wiring rain during the last 2 days.

3rd owner of the truck. Bought it from my buddy. Modification on the truck will be DSP 5 switch with 5 levels. 1. Optimize Stock ,2.Tow 3. 50ho 4. 75hp and 5. 100hp. I have the OBD 2 Flash. Far as I know only external filter has been changed along with the transmission oil

Yesterday I got this on notice on my truck. No check engine light on just Range Shifted Inhibited. I can shift From P R N. When I shift into D nothing. Shift into 3 and I am able to drive it. This morning I was able to drive it on D and with in a mile of driving it stayed on 3rd gear. While i was driving it did engage 1-5, but when i slow down it stayed at 3rd. Did some research and checked my transmission fluid level and it checked out. Forums say it may be the NSBU Switch. Order one from amazon hoping that maybe the problem. Has anyone else experience this problem? Truck is 2004 2500 HD with 175k miles.

Everything is sold out for dry camping. 1st timer heading to StageCoach, 1st Country Festival since Route 91. Any places around Indio I can dry camp with my trailer?

Differential Cover came off my 2005 2500HD. Truck got hit by a drunk driver and truck got totaled. I was able to salvage this differential cover. Was only on my truck for 3 months before it got hit. Asking for $260 obo. I am open to trades anything for Duramax LLY. Comes with all hardware. Call or text 951-258-6659

Thank you Chevy1925 will be checking it when I get home.

Monday morning notice a puddle of coolant under the front passenger side. I only notice coolant from the bottom block. I checked upper and lower hose and they were dry. Checked water pump also dry. Last week the water pump was replaced, thermostat, upper hose radiator hose, fan clutch, new coolant and coolant temperature plug. I also pressure wash the radiator front and back. Since the new parts my coolant temps been fluctuating from 180-205 (based on my edge ct2 controller). Truck is running LBZ turbo mouth piece, resonator capped off, S&B intake with air scoop, egr plate and PCV re route. Stock tune . The truck is my daily driver, I do not drive crazy and before I replaced all the parts listed above coolant levels were running around 180-185 gradually hit 190. Truck has 171k miles. I will be towing my WW next week and I will hate for it to over heat. Drove it this morning no coolant leak when I parked at the gym. But when i got to work puddle of coolant. In one of the forums I read it maybe the heater core hose. Any other ideas? I hope its not the head gasket.

they quoted me $1,450 parts and labor. OEM water pump, thermostat
