OK so I am confused, not knowing what the previous owner did or did not do I figured I would changed all fluids and know where I am at from this point forward. Not knowing what specific trans I had I called and asked the dealer to look it up using my VIN. They told me I had an AX 5 and to use 75W-90 in it, I bought 4 quarts and drained it and when I went to refill it only took a little over 2, which made me question what was wrong. I did some research and for a 01 4.0 6cyl. which I have, what I am finding is that I actually have the NV3550 which takes 2.1 quarts of Mopar or Syncromesh. I called the dealer back and they insist that my VIN indicates a 4cyl with AX 5 trans, which is not what I have. My VIN starts with (1J4FA59S) which from what I have found is right for what is sitting in my garage. I called two more dealerships and they all say that VIN is the 4cyl.??????
I know dealerships are dealerships but all three saying the same thing has me thoroughly confused, the chart I am using to decode my VIN is below. I am going to drain the 75W-90 and refill with Pennzoil Syncromesh, but I am still confused on this mix up on the dealers and the VIN. is this a common mistake for them or am I as crazy as this is all making me??
Also with having the wrong fluid in it should I run the syncromesh for a while and then drain it again and replace with syncromesh again in a week or so or just refill with the right stuff and forget it?
Thanks inadvance for any help.
