Dexron instead of ATF+4
Good day all. I just purchased a 2003 Dodge Dakota QC 4.7L 5-Speed Automatic Transmission (163000KM). The private dealer I bought it from replaced the transmission pan because he thought the old one was too rusted. When I asked him if he used ATF+4 to top up the trans fluid, he said it isn't necessary and he'd used the dexron/mercon generic stuff, and did not change the filter.
From what I understand on the forums here, it is not a good idea to use anything but Mopar ATF+4 on these transmissions. What should I do about this? Bring it to the dealer for a trans fluid/filter change? That will only change some of the fluid though correct? I was thinking flush but have heard that is no good for them wither. Please help, I don't want to kill the transmission!!
BTW- I called the local transmission shop here and they also said it is fine, and they use dexronIII on these transmissions all the time!
