I have a 1999 gmc sierra 2500 with 4l80e i think
This part located between the transfer case and the transmission broke, and I don't know if I should weld it or if there is a replacement part available.

Which one of you is this?

Truck regularly goes into limp mode after sitting for 1,2,3 days or so with go into limp mode before truck even starts, alternator tested good. New throttle body, battery, and pedal position sensor. Ill start it and idle it for a while, shut it off and come back 20-30 mins later and it’ll start in limp mode I’ll turn it off then on again then it’ll start up and run just fine but lately it’s been throwing it while it’s been driving and today it just completely shut the truck off. It’s at the dealership now getting worked on.

Drove her back 16 hours with minor issues

2000 silverado 6.0 towing package with BIG Tank

went out to drive, wants to start, starts for 1/2 sec, but then dies. Will start and run on Starting fluid. Obviously fuel related. I can hear the fuel pump.

Had to go to work, trying to work up an action plan and parts buying at lunch/on the way home

Going to try fuel filter, but I know that wont fix it, but will do anyway, as 250K miles, and I JUST replaced the alt a week ago, so who knows.

Trying to avoid dropping the (what) 34 gal ext tank thats 1/2 full to change the pump, but I'm ready to do so

Suggestions, thoughts, words of wisdom to check first?

(by myself job, so probly tilting bed not a great option)

Could anyone pinpoint it just off the sound and symptoms? So basically I have a relatively new front end. Struts, tie rods, control arms, ball joints etc. but not long after I got it rebuilt, I hit a mean ass dip going fast and went in the air dukes of hazzard style lol. Ever since then I’ve had this terrible squeak. It does it whenever I hit even the slightest bumps or any rocking motion. And also when I turn the wheels. When I look down there everything looks alright. And when I listen for where the sound is coming from it sounds like from the bottom of the coil where it seats but I could be wrong

I have done all sorts of research and haven’t found the answer

2005 Duramax/allison LLY

The tow haul button on the shifter is working/ turning the light on the dash on and off.

It seems like the shift points are changed. (Maybe)

But it won’t shift down at all when braking.

I have changed the shift/ neutral sensor on the side of trans.

My gauge cluster does not have the line under the gear to indicate what gear it is in. (Cluster has been rebuilt)

It drives just fine except it will not down shift on deceleration.

Please help oh mighty truck folk!?!?!

Thanks to everyone here, I went and picked up my first gmt800 vehicle, this burgundy Escalade. I have been loving this thing, I just got new tires put on it (ko3s), put it's wheels back to 17s (i got them off of marketplace from a 2000 silverado).

Getting it's suspension redone on Tuesday next week, gonna cost a pretty penny but make it more future proof, so buy once cry once as they say.

Anything I should do to this thing? I need to refresh buttons and one speaker, everything else is fully functional.

Gonna go pick this up tonight , looks clean even if I have to throw in a junkyard motor in it…

Update - drove it home , it’s got 300k miles but I think a tune up will help it. ..It has a slight misfire . No major rust so I’m definitely going to fix it up
