Attached is the video, jesus christ I can't afford this..

 

I can't play it. can yuh put it up on youtube?
also, so far every single tranny issue ive encountered on here was resolved with fluid unless there was an accident or some reason for the tranny to fail.
Slipping can be a fluid issue and likely is. Unless you have a manual, in which case it may be the clutch!

I've also resolved several trans slip issues by replacing fluid with redline brand fluid of the appropriate type. Wouldn't fault someone for wanting to stick with OEM juice though as I'm told these days its made specifically for the transmissions it's used in/has a specific additive package that best promotes longevity.
I switch to redline if that fluid was replaced with more oem juice, the level verified, and then the fault comes back in a couple months. you know. if theres no leaks.

 

The right side instrument gauge ... something is illuminated but I can't see clearly from the video. Have you noticed that before?

I wonder if an OBDII scanner can help narrow down the problem. Maybe someone here can chime in on that.

 

I just had transmission issues losing acceleration - not exactly like what you were experiencing, but I got a transmission fluid full flush and that solved the problem. If you haven't had your transmission fluid changed out in a long while, might be worth a try.

 

That looked like a slip to me. I had something similar a week ago.

I was climbing northbound on I15 toward Cedar City--you climb 1500 feet or so. It didn't want to do the speed limit of 80 and I didnt force it. It would do 70-75 depending on the slope at the time. I was getting some RPM spikes with no change in driving experience. If I let off the gas a touch it would maintain speed and RPM. Otherewise, it's been completely solid.

I've got a fluid change scheduled on Monday, 83OOO miles on it.

 

@dogbite Based on your description i'd suggest wiping out the throttle body too, just to make sure the plate isn't sticking.

 

I'll look into it.
