View Full Version : AOD slipping in to neutral

02-24-2009, 10:20 PM
I have found on my 89 150 that when I get any sort of heavy incline my truck likes to slip in to neutral its only in heading straight up not in reveres is this just how the pickup is or do I have some sort of issue I contemplated adding a little fluid but I donít want to push any seals any ideas ?

how "extreme" are these angles?

when the pump doesnt have oil in it the hydraulics lose pressure and let go of the clutches

have you checked the fluid level? what does it read on the dipstick?

I’m at the top of the operating range on the stick its new fluid as well I did a flush last summer and the angles well is say 25 degrees and it starts acting up but at that angle its only if I let of the gas it slips in to neutral but at 45 degrees it will go even if I’m on the gas.

might need an accululator and a fancy oil pan to go extreme angles
did it always do that or just start recently?
could be the filter/pickup slipped out of position if it is a new issue
