E40D issues

[vegas39]

Hey all. My brother in law has a 95 F150 with an E40D.
He relies on this truck to support his family and I'm trying to help him figure out his problem with it.
I drove the truck this morning when it was cold and it shifted just fine but after it warmed up, it wont take off in first gear from a stop sign, it starts off in second.
If you manually try to take off in first, it slips real bad and it feels like someone is applying the brakes.
Never seen one like this before but I was hoping someone with this trans might have an idea whats going on with it. Thanks.

Is the OD light blinking? If so, there is a trans code appearing.

Mine did the exact same thing it had to be rebuilt

What ended up being the problem with it?

Whats is the going rate for a rebuild on one of these? Thanks

mine was 2200 but it was beyond stock and a hairline crack in the plate above the valve body started it

Most likely the pump is on its way out. There could be internal leaks causing a pressure drop when hot. Either way the tranny will need a rebuild.

Thanks guys, I'll pass on the info.

He pulls a big gardening trailer around St George UT, all day long. I told him what he really needs is an old IDI with a simple C6.

Yes E4OD's can be very problematic

I've come to realize that on any given day you can look on any of these forums and there will be someone having trouble with an E4OD! I have one that keeps having TPS issues, although I think the TPS is fine and the TCU is the problem. I have another that the OD light is flashing, shifting hard, and it's not throwing any code??? Counting the days down until my ZF5 swap!!

Most of the E4OD's you read about are high millage and abused units.They have poor electronics and terrible programing. This is the stuff that gives the E4OD a bad name.
