    I did a search but could not find what I needed so I am asking in here. I just had my tranny rebuilt (94 F150 E4OD). Before I had to have it rebuilt it would clunk or bang into reverse 70% of the time and seem to go into reverse nice and smooth the other30%. Well after spending $1590.00 to make it as "heavy duty" as possible it still bangs or clunks into reverse, is this normanl for this tranny?

    Sure is,
    And if you are thinking of snow plowing or towing a trailer make sure you have an aux. trans cooler.

    electronic 4 wheel drive w/ overdrive is not a heavy duty trans

    scott, i hate to say it, but having the trans rebuilt isnt going to fix that problem, i had the same trans and problem, what causes the clunk in reverse is either bad u-joints and or tailshaft, possibly problem with the rear end or stub shaft, but the trans rebuild wont help unfortunatly, good luck

    E40D means Electronic, 4 Speed, with Over Drive, not 4 wheel drive.

    The E40D is a heavy duty transmission--it replaced the C6. Somethings that a do it yourselfer can do to help improve longevity in these units is a deeper tranny pan such as one from Mag-Hytec, which has cooling fins on the bottom and is deeper. Another thing is to swap in a Power Stroke tranny cooler, which is overkill for a F-150, but is well worth the effort if you want a long lasting unit. The other thing that will help is changing fluid every 20-30k.

    The early ones had their weaknesses in flow capacity and solenoid issues, but those can be corrected with the abundant aftermarket available such as from the people below.

    Specifically, Brian's Truck Shop in Arkansas (BTS), John Wood in California, and Suncoast Transmissions in Ca. are experts on making the E40D a bulletproof heavy hauler.

    Good luck on the rear end...

    The slip yoke is what causes the 'clunk', that's what it was in my old truck, and I never had any problems with the E40D in it.

    A clunk in reverse sounds like sloppy u-joints.

    Smalltimer: The E40D doesn't circulate fluid in reverse...that cost me a input shaft and a torque converter...But you can keep thinking its a heavy duty transmission, and that you can change compression by changing the rings :laugh:

    U-joints can cause it too, but in that body of truck, the slip yoke is usually the culprit, I worked at a Ford dealer last summer and replaced several of those to cure that problem.

    I don't see you pulling a 6 ton hay wagon at 5mph for 3 hours, mine did it for years with NO trouble. Had no trouble backing it UP the hill into the barn either. Goof Ball Holland strikes again!:D

    Call these guys on the phone and they will help you diagnose your problem. They told me what to check for when I was having trouble with my 4R70W auto tranny in my F-150 and it turned out to be a very simple fix that I did myself in about 1/2 hour. I too was getting ready to drop $1500 to have my tranny rebuilt.
