Stuck in limp mode! please help!
 

My Mitsubishi shogun elegance is stuck in 2nd gear... limp mode. Its automatic. The ABS and traction controll light and airbag lights are stuck on. Ive had a diagnostic and it says possible wiring fault, possible fault with auto box, maybe a solonoid. Its cost £143 so far and nothing has been sorted, Feel like ive been ripped off big time. Mitsubishi garage are charging £75 an hour to try and work out what the problem is, and they still havent come up with an answer! Can anyone help me? Has anyone had this problem? Write back, thanks.
