I have a 2003 GMC sonoma 4.3l zr2 sonoma. I seen a local ad for a 4.8 2001 4x4 chev. Is this the same transmission by any chance? Thanks in advance.

Yup but some guts maybe different ....one Smaller clutch pack as I remember depending on engine

 

RPO trans code will tell all my son, consult your dealer parts dept for more info

According to the chart on their transmission site. It's the same. If some guts were different, would it cause problems? Or just shift a little differently?

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      Howdy folks,   Recently I pulled a heated steering wheel and clock spring out of a 2015 Sierra All Terrain (part numbers coming soon - will have to disassemble), and just installed it on my 2016 Sierra WT (as base model as it gets).   On install, I noticed that I’m missing the connector often tucked behind the dash for the heating element.     No problem… or so I thought.   I used an “Add-A-Fuse” at my heated steering wheel fuse location, which has voltage, but no wires. I ran it to the positive of the heated steering wheel (Violet/White), and took black to ground.   Hooked up the battery, turned the truck on - no heated steering wheel. No button backlights. Was pleased to see that my cruise control was working though.   Read a post suggesting reversing polarity, so I gave it a shot. Violet and White to ground, Black to power.    Aha! Heat! But I seemingly can’t turn it off AND still no backlights on any of the buttons.    Checked all fuses, everything is still in good order. I’m stumped.   Does anyone have any insight? If so, please share!

      I'm about 1800 miles into my last oil change, and yesterday a message appeared saying oil life was at 77%. Not sure why it popped up but I think all of these electronics could be susceptible to solar flares or somesuch. I change my oil right at 3K each time, and that was the first time in 10870 miles that message came up. Strange thing is that it showed on the screen at all since I don't drive with that sort of info displayed on the DIC.

      Checked the pads today and there's plenty of meat on them. If the message keeps coming up, I'll just answer YES that the pads were replaced and wait for the squeal.
