Torque Converter/Trans/Comp problem?
Hey guys havent been on the forums here in seven years since i sold my '86 f150. About 8 months ago I bought a '96 F-250 5.8 E4OD 2W. The truck had about 150k on it and was already on its second motor/trans due to the previous owner towing horses and such. Anyway about day three of owning the truck i was driving a trailer on the highway with OD off and my little light on the shifter indicating OD was flashing and the trans was slipping in and out of 3rd. It freaked me out for about 10 minutes and then stopped. 8 months later, just this week same thing happened again for an entire thirty minute drive (no load and OD on) I drove it home waited 30 minutes got in and no problems. So i guess what im getting at is what is up with the flashing OD light and the trans slipping in and out of gear? Also another thing to mention is that when they connect each gear kicks real hard. This makes me think bad torque converter but you guys are the experts.
Thanks
Matt

They are NOT garbage, they are completely computer controlled, and as with a wife, if the computer ain't happy the trans ain't happy
.. It sounds like you have a little something off somewhere causing the trans to go into LIMP mode.BTW Welcome to FTE....

i have never heard of LIMP mode. looked it up, sounds very possible. im gonna grab an OBD reader and check to see what is going on. although i know its kinda rare for a vehicle to throw codes with no check engine lights (etc) on. thanks for the help. and if i truly believed the autos were garbage i would not be a 4 time FT owner.

One of our work trucks is a 2000 f550. It has had that same issue for years (maintenance says "it's fine ") and we have been driving it that way for over two years now. Not saying leave it just saying it probably won't tear up tomorrow.

but I just get tired of people saying they are garbage when 95% of the time it's an issue causing the trans to go into limp mode, then they just blame the "garbage" trans and not even look for the real problem...
Yes, it's possible to have (CM) codes stored and never have a check engine light.. The slamming into gear is the failsafe mode of full line pressure to keep the trans from slipping and building up extreme heat which will destroy it in no time....

Does your speedometer work correctly when you are having the problems?
If not it may be a dirty conection at the VSS on the rear axle.. Those are exposed to all the road grime/moisture year round.. They are a sealed connector but we know the seal/ orings have a habit of going bad and letting moisture in,,, And that's all it takes to corrode the connectors....
Since your problem comes and goes it a good possibility it's the VSS or some other dirty connection..
Good luck....

Back about 10 years I had my transmission rebuilt at Amco Transmissions with a life time warranty. Well, within a year it was rebuilt maybe 12 times and they dropped me from their plan.
So, I went to the Ford dealer and talked to a few of the mechanics. One of the mechanics decided that he wanted to drive the truck and test it out. He then told me that a E4OD if a tough transmission and should not be breaking at all with this puny 5.0 motor. The only way that your truck is eating though transmissions is because you have a warped casing or the people have no clue on how to rebuild a transmission.
I got a lawyer and sued the transmission company. I won all the money +more. I then had the transmission rebuilt with a different casing and I have not had any troubles with it since.. The first casing I think was Aluminum which "I guess got hot and warped some how." The new casing is Cast Iron.
Figured I would throw that out their for people having repeated tranny problems with a E4OD

If the computer detects a problem with the transmission, it will usually kick the line pressure up to maximum to try and prevent slippage. Generally a flashing OD light indicates a serious issue with the transmission at that moment and will usually set a code. The code may not always trigger a CEL though.
You do not have a cast iron E4OD housing as they were never made in cast iron. What often happens, is that the center support bolts are over-torqued, which can warp the valve body surface.
