E4OD Shifting in and out of OD.

'95 F350, C&C Dually Dump. 106,xxx miles.
Last year, I had the trans rebuilt by a very respectable shop. I work the truck extremely hard, and I have been very happy with the trans.
The truck, with both tanks full, and me sitting in it weighs right about 8000lbs. I've been hauling my bobcat and trailer and they weigh an additional 13000lbs.
Anyway, last night, taking off at the bottom of a couple of hills, I could hear the pump whine. It's all back road driving to get home for about 22-23 miles. I have always manually used OD once up to cruising speed, so the trans doesn't have to "hunt" for gears.
Once I would get up to a cruising speed, the trans would start shifting in and out of OD. If I either let off the throttle, or stepped on it, it would straighten up.
Also, if I manually took it out of OD, it worked fine, too.
When I got home, I checked the fluid, but I couldn't tell with that damned yellow dipstick. So, I dumped a quart in it. I unhooked the trailer, drove hard for a few miles, and it acted fine.
Think it might have just been low on fluid? Any thoughts? If it acts up again, I'll call Leonard at the trans shop, and see what he thinks. He is well known for guaranteeing his work.
Just wanted to throw it out and see what you all thought.

Re: E4OD Shifting in and out of OD.

the stick is a bit hard to see. I tip it over and try to see the difference between shiny and non shiny. that way it a bit easier to see..

sounds like you might have been a bit low.. check it cold level ground and see where you are on fluid level..

So far, it's acting fine. I haven't had the bobcat hooked to it. But I have had the dump filled with sand a couple of times. There's a little red around the gasket. All the bolts took 1/2 a turn to tighten. Maybe it was just a little low.
