Spreading the wealth tonight because there are knowledgable people in all these groups.
In order to try to make sure my '92 Grand Caravan has the proper ATF, which is now ATF+4, I did a drain and fill and replace 5.5 qts of trans fluid with Castorl ATF+4 grade ATF. It is running OK, but sometimes "Bump-shifts" which in these trannies can be an indication maybe someone put in the wrong fluid.
My plan is to drive it 1-2,000 miles and then do another drain and fill (which will put me right about the middle of January, and of course, there's no quick and easy drain plug...)
How many times does anyone think I need to do this to make sure there's enough ATF+4 to cover my behind? I could put some extra effort into it and flush it...NAH!
I can't quickly find the fluid capacity of the tranny...
