i have a 90 bronco with an aod not the aod-e she has like 15k on a rebuild, so here's the problem, when i have the truck in overdrive and i slow down to a stop the second to first shift is pretty rough almost like it's holding the gear too long then it bogs the motor bad before it shifts almost to the point of killing the engine, i've seen the needle drop under 500rpm. but then if i just put the truck in "d" disabling the overdrive the transmission works beautifully, but with my 4.56's she just guzzles gas. i had the truck back in the shop under warranty the guy cleaned out the valve body and did a visual on the internals he could see and said the overdrive belt looks brand new and there wasn't any metal shavings in the fluid, and tips or idea's would be much appreciated
