I have around 200k on my 95 F-150 with the stock e4od. I changed to a B&M valve body with TransGo shift kit back when it had around 80k on the clock. No reason, I just wanted better shifting and the ability to handle more power from my worked over 351W. I wheel the truck hard offroad and mud race it quite frequently. I am getting ready to start another season with this tranny. My only wish is for someone to come up with a transbrake for it. Seems no one uses this tranny in racing applications.

 

'95 E4OD in F350 Crewcab, currently has 85K miles on it. No problems at all, no shudder, no slip, strong lockup. I haul a heavy boat and loaded flatbed. New fluid and filter at 70K.

Hope i get 200K like some of youse guys!

 

Huh...

My E4OD has been nothing but trouble.

I don't know why, I don't know it's history as to how it was driven etc. I know the tranny was taken out of a wrecked truck, that might be part of it.

Could it be that it has 271K miles on it?

 

I wonder if the problems you describe are the result of a higher stall speed on the converter? Did it act this way before you changed the torque converter?

I will replace my torque converter at some point, but my tuner told me that I'd have to alter my tune to account for it....something that you note your tuner can't do.

 

nooo... this is at least the second tranny. The one thats in the truck now is supposed to be a fairly recent rebuild, as the truck that was wrecked was recently rebuilt. The engine was fairly new (less than 10k) and the tranny was rebuilt at the same time.

I don't know what it is... but I know it's not that!

oh... and it's 273k now...

 

Haha I was just wondering. I figured that wasnt the original tranny.

 

I haven't hear anyone mention it lately, but I always shift to direct drive any time my auto trans. unlocks the converter under heavy load. I haven't had any problems, towing some pretty bizarre things. Also I unplug the compressor and turn on the ac (to run the fans and cool the trans oil) under extreme conditions. Is this common knowledge? I just try to help. diesel_john

 

I have not changed the converter and I believe it's original. I compare it whith my 82-F250 400 C6 2wd, it has torque from idle and a converter that deliver it, not much slippage. The 400 has max tq at around 2000 rpm and the 96-351 has it at 2800 rpm and I also understand that the 351 does not have that low end grunt as the 400. The E4OD converter doesn't deliver much tq below 1500 rpm and light acceleration is 1500-2000, for the 82-C6 converter it's about idle-1500 rpm.
Does the 2wd 150 have different tqconverter than a 4wd, for 1996, or can the converter get that worn to be more slippery? When I bought the truck it had 37000 km on it, and nearly as new, now 63000 km.
Well, I think I can live whith this tranny and the mainthing here is a bit too late shifts, and I really want to achive the situation permanently, when disconnect and reconnect the battery because the shiftsituation is much better all the way and I do not note that much slippage in the converter when the the shifts comes earlier.
Has anyone used a chip or tuner to changed the shift-pionts in a 96-150 5.8 E4OD 4x4?

 

@ Months ago I bought a 1997 Super Duty with an 11ft utility body planning on making a service truck out of it. The seller claimed the tranny (E4OD) was rebuilt. It drove fine until it warmed up. Then it would stall the engine every time I would shift it into reverse or manually shift it into 1st. Took it to a tranny shop and had it rebuilt. When I went to pick it up I told them that this truck will weigh about 14,000lbs when I get done putting my equipment on it. The truck is rated at 15,000lbs so I'm not overloading the truck. They told me that I will probably be a good customer of theirs since the transmission is hooked up to a 7.3 PSD. Automatics aren't ment to work at the low RPM's of a diesel engine contrary to what Ford Gm and Dodge will say, expecially if you are working them hard every time you turn the key. For occasional towing you probably won't notice any problems. These guys installed an aftermarket torque converter and filled it up with synthetic trans fluid. It already has a transmission cooler. They did not install a high capacity pan because it would lower the pan about 4 inches and they were afraid that if I got on a job site off road I could put a hole in it. Heat is the #1 enemy of your transmission. Keep it cool with an external cooler if you haven't got one. Use synthetic fluid, that will reduce friction which is where the heat comes from. And change the fluid and filter regularly.

 

If it's the factory cooler, you may want to consider adding another one. I know a lot of folks have done this, including me.

IMHO the factory cooler is inadequate, it doesn't do a great job under extreme conditions. With the additional cooler, my fluid temps are significantly lower when pulling 7,000 lb. thru the desert.

With the supercharger, my tranny temps can rise even when I'm not towing.
