2013 ram 1500 stuck in 4th gear

[Surinderr]

Hi , I have an 2013 Ram 1500, 5.7 hemi.

Earlier today, I boosted a semi truck. After that, I shut the Ram off and was parked for around 20 minutes. I moved the truck slightly, then shut it off again. All was good. A little later, I started it up — and suddenly the engine light came on, and it seems to be stuck in 4th gear (limp mode).

I drove it a few meters to confirm — still stuck. I then:

• Disconnected the battery for 10+ minutes
• Plugged it back in
• Still stuck in 4th
• Check Engine Light still on

Anyone experienced this before? Could boosting the semi have triggered something electrical? Any advice on what to check next — fuses, sensors, solenoids?

Thanks in advance!

Did you scan it for trans codes? It is probably a valve body issue is it the 6 speed? How many miles on it?

Yeah you shouldn't jump a truck with a passenger vehicle.
