My E4OD in a 5.8L gas 1993 e350 17" boxtruck Grumman conversion
was purchased
not going into reverse.
AAA couldn't reach it, from the mile of washed out dirt roads, with the extreme hills & curves the owner had it on,
so I drove it to the AAA wrecker.
It was towed 25 miles, to a parking pad, next to an apt.
Didn't see any leaks under the chassis while I was
getting rid of the roof leaks & mold,
then retrofitting the box insides into a workshop.
Started to drive it out of the pad,
got past the fire hydrant,
tuned 90 degrees & into the street
so AAA could move to next spot.
(still hadn't tagged & titled)
That's when the gas pedal decided to latch down,
& I got some smoke into the cab
& I feathered the gas to unstick it
(farmers learn to NOT panic).
Then would not drive forward any more.

Towed it to a church I do volunteer car repair with
& noticed leaks at the transmission cooler, upon the radiator.
Replaced those hoses,
Put in some Lucas products,
but no joy.

So, anyone have good experiences at this point
replacing the solenoid pack,
or any simple band work,
or a junkyard E4OD of compatible years?

Thanks kindly!

P.S.
Am I missing any years/models?

The solenoid pack cannot cause no gears.

The only band in the transmission is only used when the shift handle is in the 2 position. If it isn't in the 2 position the band is not being used. So bands are not the problem.

It could be too low on fluid to engage. Or the feed bolts between the valve body and the case are loose. Or the trans pr torque converter has failed. It's one of those.

If you get a used E4OD you MUST get one from a two wheel drive truck with a 5.8L. Anything else will cause you trouble.

 

Thanks for the feedback, Mark;
Would I have to bleed/burp the transmission cooler?

Anyone seen a diagnostic text (or video) for diagnosing the option(s) Mark outlined?

 

You don't need to bleed or burp the coolers.

I don't have videos, but here is how you diagnose the options I listed above.

1. Sart the engine, eaving the shifter in park. Check the transmission fluid level. If it is below the hatch marks, add a quart and check again.

2. To diagnose loose feed bolts, remove the pan and the valve body. The bolts will be in the case above you, dripping fluid. Here is a photo of them.



If they are not loose, remove the transmission and torque converter. Rebuild or replace them. There is no point to any further diagnostics, it would all point to something mechanical broke inside the transmission.
