More E4OD Issues
I have a 96 F250 4x4 with 460 & E4OD. I recently (about 18 months ago and 3,000 miles) rebuilt my E4OD. I had some initial issues with the Tugger Shift kit but once that was resolved everything has been working great until recently. Now there are a couple issues...
It started when i was cruising down the highway and the rpms increased and the truck started to slow. I kicked it out of OD and everything seemed to be fine. after a few miles of driving i put it back in OD and everything seemed to be working as it should. This happened again yesterday on the way home and after a few miles with OD it was fine.
The other issue: I recenly had to help a buddy out of a mud hole. I used the winch to get him out but when i went to move I had to give it some throttle in reverse to get out. After that it started shifting into reverse really hard. the next day i ran into a similar situation where i had to give it some throttle in reverse and now i have no reverse. I can feel it engage in reverse but as soon as any power is required it just starts to slip and wont go anywhere.
I just changed the fluid and filter before we left for our trip.
Anybody have a similar experience or any suggestions?

Do you have any problems with "kick down" meaning automatic down shifting?
Take Care.

was this your first time rebuilding an e40d?
post up more details on the issue with the tugger shift kit if you would,and though you claimed to have flushed the trans,you didn't specifically say that you insured the fluid level was perfect when warm.

Any chance the filter dropped off completely or part way, get the old seal out first before putting the new filter in place? Often removing the old filter leaves its seal in place, not noticeable right of if not watching for it.
First I'd run the self test and then check the pressure , reverse requires higher value over that of any other gear.
Should be 75 to 130psi hot at idle, 240 to 256psi hot at stall.
Pressure tap located just above the pan and forward of MLPS.

Boonslick - There are no problems with kickdowns. Other then the two issues the tranny works like it should.
Yes this was my first time rebuilding an E4OD. I had lots of support from a couple of Ford Tranny techs. The problem with the shift kit was there is an option for it to hold first at any speed and i put that option in unknowningly. Once that option was removed everything worked as it should.
Yes the tranny fluid was checked when it was warm and it was perfect.

If the rearmost bolt on the valve body plate is loose, it'll vent pressure for the low/reverse band servo, and will not have reverse/delayed engagement/slipping reverse.
I'd drop the pan, check the filter and every valvebody bolt.

Thanks Ian. I will check those bolts but wouldnt this problem show almost instantly and create other issues?
Yes I verified the seal came off with the old filter and a new filter & seal was installed. I dont not believe the filter has fallen off because i made a bracket to hold the filter in place but i will verify when i dig in to check the valvebody bolts.

Many conditions can lead to loss of reverse, I'd start by checking for KOEO self test codes and pressure test before dropping the pan.
Info both those tests provide would provide direction to go once inside if/when it came time to drop the pan.
"no reverse" partial list,
Fluid level, low
manual linkage, mis adjusted disconnected damaged etc etc
Filter issues, plugged (fairly safe bet not the problem)
valve body/pump control bolts loose or to tight
dirty sticky valves (doubt it just had it all apart, would seem safe enough assume its clean inside)
direct clutch accumulator reg valve stuck/dirty
BS5 check ball missing/plate seat damaged
coast clutch assembly leaking
reverse clutch burnt plates/damaged piston/seals
Exactly how it acts in all forward gears also comes into play determining cause of problem.

Just checked the KOEO and came back with a 111 (All systems OK). I will have to check the pressures once i get a gauge.
all forward gears feel solid with solid shifts. the only issue i have had recently with forward gears is what i mentioned at the beginning with the OD randomly slipping and then working after a few miles of running in third.

so i was able to do part of the line pressure test. We got some snow so i wasnt able to do the WOT in OD,2 or 1. I dont have a garage i can put the truck in.
Here is what i got:
P, R, N, OD, 2 &1 were all about 85psi at idle
R was 100 psi at WOT (thats about 150psi below the recommended)

Well i ordered new VB gaskets and they finally came in yesterday. I went to install them and had a big surprise when i dropped the pan...fluid was burnt and the bottom of the pan was full of clutch material. Looks like I will be pulling it back out and starting over with a new rebuild. Thanks for the help.

Clutches just don't generally burn, especially after a new rebuild. I'd go over all the piston/clutch apply seals carefully. Make sure the clutches have proper clearance as well.
Another thing that can sometimes happens, is that the various valves in the valve body can stick and cause two opposing clutches to apply at the same time. I'd go through the entire valve body with a pick-tool and verify that each valve moves freely through its entire travel.
