I did make sure the collar in there wasn't damaged, but it wasn't a super tight fit by any means, just kind of slid in there with little effort. Could fluid getting past the filter be my problem?
And if I do drop the pan again, what brand of Dex 3 should I use? I have 4 qts of Mobil1 Synthetic dex 3 in my garage, do people have good results with that stuff?
The dex 6 did make the car a lot smoother in general, but I'm just concerned about the longer shifts. I tried to make it do the weird shifts this morning however, and it didn't do it. I removed the battery soon after the fluid change, could the PCM still be adjusting?
