ENGINE CHECK LIGHT- Gears stuck
 

Help!!, I have a 2005 Grand Voyager 2.8 CRD auto ,with 35k mileage. Warranty has just expired Jan 2008. Ive had it from new, with no probs. The engine check light came on last month and as a result the gears are not changing and seem to have got stuck in 2nd everytime i drive. However on occassional random starts it drives as normal then gets stuck in 2nd. Ive shown it to Chrysler, who have reset the codes 3 timesand this time said it was a £11 relay,after spending £200 on their labour costs , drove it out of the garage and had the same problem, light came on ,gears stuck in 2nd.Theyve now suggested it may require a new wireloom, this could cost thousands!! Its all guess work.

I tried the key dance and had a code of P1685 show up, which icant understand, as i have the original key . can anyone help please?????????:(
