Emergency help... Transmission

[89Suburban]

Was the tow/haul mode engaged? Are you in 2WD?

Truck will go into gear and pull forward, but feels like there is some hesitation.

From what you describe, it sounds like transmission related.

May have a busted sprag or pump or converter.

ill go with swathdriver's guess. The fact that it occured upon a downshift and when you attempt to move the vehicle you feel/sense resistance you are likely losing line pressure through an internal leak. broken/fractured clutch housing/application piston. it is odd that the engine died? no trans issue should shut the engine off? are you sure it didnt vapor lock? it is so hard to accurately "guess", put it in drive and limp to an off ramp, how far are you from your destination? find a safe place to spend the night in the trailer and make a plan for the morning?

I've got an 11 suburban, ltz, 4x4,towing pkg. Pulling a 3k lb trailer, and a loaded cab area. In Colorado, pulling up a pass. Truck down shifted to 4th gear, and felt like something popped, engine died. Temp was running 160ish before the pass, and got up to 200 when it happened. Any ideas? Truck will go into gear and pull forward, but feels like there is some hesitation. Thanks. Currently sitting on the side of the road.

and thats why we use manual(M) mode to cap the gear from blowing the transmission. on the uphill....

Here's my guess if it runs and moves ..fuel pump is taking a dump ran lean that's the pop in motor and pressure low in fuel lines is my guess . It's a long shot .
Second thought you dropped lifter in the active fuel management .I just noticed it was 2011.. [emoji106]

I was in manual mode. Downshifted it to 4th when it happened. Was able to limp to nearest town.
Tube for dip stick was busted. Replaced that, all fluid was burned. Did a flush and service on tranny and seems to be running fine now. No codes, and didn't do anything weird after the fact. Sorry it's taken awhile for an update, we're up in the mountains and don't have signal.
