Re: SERVICE 4WD SYSTEM Notice
The $175 is not too bad, if they're willing to include it in the final bill. If you end up not having them do the work, they want to be paid for their time and overhead. (They still have to pay the technician). The $175 is a bit high for a normal diagnosis, but when it comes to transmissions and 4x4 systems, sometimes they have to take a 'closer' look at things which entails more time.
In your case, the technician may go over every harness, every wire, checking for shorts, proper voltage, and using a scan device that can narrow things down compared to a scan tool you borrow from AutoZone.
Some people prefer dealerships, some don't because they have a reputation at being much higher in price, although I have found that not to be true in all cases.
In my opinion, when it comes to transmission and 4x4 issues, going to the dealer may not be a bad idea. You can always walk away if you need too. Your dealer has more experience with your make and model, plus they have the proper equipment to make an accurate diagnosis.
Last, look at your paperwork and see if you have anything covered by any type of warranty. Even when your actual warranty expires, there are A LOT of things covered until 80,000 miles. Guess what? a lot of these items are 4x4 and transmission related!
Usually you can look at the 'Buyers Guide" and it should tell you.
I just had a ECM go out and in small print, I learned it was covered!! And I was prepared to PAY for it too!! It would have been over $900!!
I hope this helps, if not, we least compared notes!
