Thank you so much for that detailed response. Yeah that's the stuff I saw when I was looking on Amazon, so I ordered two quarts of it. I'll go ahead and do the transmission as well, even though the manual doesn't say it's required. Fluid is so cheap it's the smart thing to do. I found what looks like the right stuff on Amazon, some Mopar ATF +4. I guess my mechanic will know how much to add, but if you've got a number that'll help as well. According to Amazon this transmission filter is for my car. Does this look like the right thing or is there a different brand or style I should be looking for?
