So i have a 2015. Has a twin turbo setup and a cp3 10mm setup on it, stock transmission been good for about 50,000 miles with no problems.. as you can tell i dont really drive my truck hard at all.

So i few days before we had a snow storm, i had a few parking lots to plow. No issues, never had any slipping, truck was used again the day after no issue, sat for a day, and then last night my girl wanted me to come by so i left my house, let it warm up 1 remote start cycle and then left. I pulled from the stop sign the truck basically went like into neutral and then jammed into gear which from what ive been told is the limp mode enabling... then i got a p0700 and a p0716 problem. I was going to buy a sensor today but i realized and found out it was internal on the transmission and i really dont want to be bothered.. Any other ideas what could have went bad? Possibly the harness or anything like that? Because if im going to have to open up the transmission and drop the fluid im just going to end up building the transmission and turning the power up on my truck.


Thanks

Mark

Turbine speed sensor bad or possibly wires to the sensor. Burnt clutches causing no gear train pull down at a stop. I'm guessing clutches.

Thats what happens when it limps, stays in 3rd. Disconnecting batteries resets the codes. It will happen again, and it happens easier and easier each time it happens. Next time read codes before resetting.

What did you do immediately before it happened?

literally remote started the truck for 1 cycle, 10 minutes, and then went out started it turned around got to my stop sign and went to go and when i was in 2nd gear it did the slip and grab and engine light, i pulled code all 4 times it happened and i reset it.. it was the P0700 and P0716 .. Wasnt even on the throttle much, maybe 10%

Have you dropped the pan yet? How much clutch material was/is there? Fluid burnt?

You’re running twins and a bigger pump on a stock trans. I’d bet money your clutches are fried af.

yea i was told it wouldnt last 5-10k miles.. glad i got 50k out of it.. im thinking the snow storm i plowed in the other day might have burnt them up we had like 16 inches of snow and it was heavy pushes.

Better make sure it's the trans first, could be the truck causing problems...

Nah, his trans is toast next week or the week after if it isn't yet ;). Might as well utilise all the fun stuff under the hood for a change. Glad Mike chimed in and you got in touch with Evan as well.

So just pulled my connector to the sensor and checked the wiring didnt see any issues and reconnected it and the truck just drove fine for about 25 miles stop and go.. so i guess ill see how it goes over the next few days.
