Does the 4R100 Pump in Park?
I've had a few E4OD's in F150's and Bronco's before and thankfully they've been good to me. I was younger and didn't really do a bunch of looking into the trans before I moved on.
My question is, with my 2002 4R100 does it pump fluid in park? Is there any gears where fluid is not pumped - Neutral/Reverse? I've searched and seem to be finding some conflicting information.
Reason I ask, I use the truck to primarily tow my 27' Fifth Wheel and to Plow snow in the winter. I had a Ram V10 that I knew did not pump while in Park, so anytime it idled I left it in Neutral with the ebrake on to allow it to cool down.
My plans are to run a Derale Pan and a Hayden Tranny cooler with electric fan as well. Thanks in advance!
