The transmission will not shift out off 2nd gear. I can't go past 25 mph. I took it to the dealership and was told the input shaft speed sensor 2 circuit found valve body internal fault. Okay so just replace the sensor right? Not for the $1500.00 the dealership wants to charge us for it. $800 for the part and $700 for labor. REALLY!!! Please help!!!!!! Surely a little sensor can be for way less than that and I'm pretty sure it doesn't take 5-7 hrs to fix it for them to charge that much for labor! If I can find the part and fix it myself I can probably save tons of money that I don't have. I need help with finding the part and then instructions on how to replace it. Please Please Help me!! I love my Nitro but after already replacing the TIPM it's getting to be too much!
