Hello all, I'm going to be adding the transmission oil cooler (GM Part Number 23409058) to my 2020 Trail Boss. I’m going to order the ACDelco Oil cooler lines (GM Part Number 86560008). Does anyone have any detailed photos of how the lines are run under the body, through the engine compartment, and out of the core support to their cooler? Any help is greatly appreciated. Thank you so much!

I have a 2004 Sierra 4.3l v6 that has started to run pretty rough on idle like it wants to bog out, I noticed my exhaust tips black (don't know if that matters). I checked the codes and got the P0300 code random misfire. I have replaced the spark plugs and the spark plug wires as well as the ignition coil, distributor and the distributor cap. That did not seem to solve the problem and I've ran out of ideas. Anyone might have some insight on what it could be that is causing this P0300 code?

i Have a 1995 gmc sonoma 4x4 with a 4.3l v6, when accelerating, it will pop through the carb? it only does this a couple time, sometimes only once and then accelerates?, which is more likely fuel pressure, vacuum leaks, distributor cap and wires? appreciate the input thanks!

Hi! So about 2 months ago my fuel pump went out. Had it replaced and right away we noticed sometimes it would crank but No start. After a few days the pump was defective, so replaced it again. Pump ran great with good pressure but after about a week or so, same issue crank but no start. Sprayed some starter in the manifold sometimes start, sometimes no. Turn key on/off to cycle and then sometimes start, sometimes no. Used the pressure valve behind the spider to bleed air/fuel then engine start fine. Would run fine for a couple days up to a week and then same thing all over again. Took it to local chevy. Diagnosed fuel pump, ... good to go they said, everything working properly. 2 days later No start and this time cannot get it to turn over, pressure is at zero. Pump is still turning on but not humming like it was. Replaced MAF and distributor cap as well as fuel filter. My local mechanic and I are stumped, and I'm already $1000 in on repairs. Please help!

Hello all. I own an 18 Silverado 1500 LT , double cab, 6’6” box, 6 spd transmission, I have opted to put 26” status alloy empire wheels with tire size of 305/26/30. Stock transmission gave out. Stock Transmission went out. They said torque converter and pump went out then everything else went with it. Was able to replace the entire unit with a remanufactured from GM. 1 month later, back to the shop (dealer). They covered the repairs because it was under warranty but if it goes out again they won’t because they believe it is the rims causing the trouble. However they will cover if it goes out with stock wheels. Which I will be putting back on. Has anyone else experienced issues with this type of truck and 26” wheels? I did research the “Unsprung weight” makes some sense, however only the transmission gave out, not my drive shaft, drive shaft knuckles, diff, just the goofy transmission which I know the 8 speed has had their share of ongoing things. How is it that a truck that is capable of towing 9k lbs has issues with no load on 26” rims. Pulling a payload in the bed of the truck and pulling a trailer should still have the same effect. If I can’t tow anything with the truck, then what is the point of a truck. I have went back to stock rims to see what would happen. Anyone with info ,thought , something sketched on a cocktail napkin would be greatly appreciated. I do thank you all for your time on this. I have attached the service ticket to this post.
