Hello

I got a jeep wrangler JK 2012, the gear stuck at 2. I tried to use the tip elec but it didn't work. I also got engine light on.
My gear has a 315/70R17 tyres and ring and pinion 4:10, I took to the dealer and the could not figure out what is the problem
So they decided to open the gear box which I refused. Could any one help me to solve this problem.

Is it under warranty? Let them do it. That's a real problem.

Why would you not allow them to complete the work?

x2, if the dealer cant repair it / figure it out after disassembly they may have to just get you a new trans....Let the warranty work for you.....

that's weird I know you can manually shift on an 12 auto. my wife has done it to me several times with her purse hitting the shifter.. man why is there not an option to turn this off it really aggravating when driving down the road and all of a sudden it starts redlining..

your trans is obviously stuck in limp mode for some reason.

A few questions.

Have you changed to aftermarket diff gears?
Have you used a tuner?

It is likely the transmission is throwing a fault and thus putting it in limp.

Could be as easy as a valve body. Could be as bad as a new trans.

Happened to me in an '05 TJ... That's limp mode to get you home. I ended up with a tranny rebuild. (Under powertrain warranty).

I used a tuner, that's what I thought first so I tuned again, but still nothing change,
When I asked the dealer they said to open the gear box and they not sure if the problem is there or not.
Because my car is modified, the warranty no longer rule, a stupid rule!!!

Try the tune again. This happend to me with my trinitry when I wasn't following the directions properly when turning the key on and off

put it back in the mode it was in before you had problem or try disco battery and see if ecm will reset
