1993 Ford Bronco E4OD Punisher Valve Body Install

1993 Ford Bronco · Install · Expert

Documented by SuperMotors from Dmanic’s photos

A Punisher valve body was installed in the E4OD automatic transmission of a 1993 Bronco, along with a new filter and pan gasket. The photos cover the pan drop and drain, the valve body swap, the refill and a break-in note, and Dmanic says the truck had been shifting loosely before the change. The album ends with a photo of the finished truck.

  1. Step 1

    Lay out the valve body and the paperwork supplied with it before starting. Dmanic says the truck felt loose and slipping before the change. The first valve body he received shifted firmly but with more kick than he wanted, so a second one was set up to the feel he described, and he reports about 6 months of use on it with no complaints.

    So here%u2019s a quick write-up on installing Paul%u2019s Punisher valve body. I wasn%u2019t happy with the way my Bronco was shifting. It… (1993 Ford Bronco)

  2. Step 2

    Unplug the negative battery terminal, which also resets the computer so it can learn the new valve body once it is in. Dmanic removed both terminals.

    First, as with anything you do on your Bronco. Unplug the negative battery terminal. You also do this to reset the computer, so it can lear… (1993 Ford Bronco)

  3. Step 3

    Pull the bolts from the transmission pan, taking the front row out completely first, then dropping the side bolts down a little and sliding a container underneath to catch the fluid. Remove the rear bolts next, then work the side bolts out slowly from the front so the fluid drains from one edge instead of all sides at once.

    Pull the bolts from your transmission pan. I usually start by taking the ones completely out across the front, then drop the ones down the… (1993 Ford Bronco)

  4. Step 4

    Remove the pan and pour the remaining fluid into the container. Pull the filter from the transmission with the container close, since about another ½ quart comes out of it.

    I then remove the pan and pour the rest into the container. Next pull the filter from the transmission. You%u2019re probably going to get a… (1993 Ford Bronco)

  5. Step 5

    Pull the filter O ring out of the transmission carefully, as it sometimes stays stuck up inside. A finger is usually enough, but a hook may be needed, and care is required not to scratch the inside.

    Make sure you carefully pull the filter O ring out from the transmission as well. Sometimes it gets stuck up in there. Usually you can pull… (1993 Ford Bronco)

  6. Step 6

    Clean the pan out thoroughly while the rest of the fluid drips into the container, leaving no old gasket material behind. Clear any debris off the magnet.

    I usually clean out the pan and make sure there is not gasket left while the rest of the transmission fluid drips from the bottom into the… (1993 Ford Bronco)

  7. Step 7

    With the filter out, remove the fasteners holding the valve body. Dmanic counted 11 bolts and 2 nuts.

    Once the filter is out, you can start pulling the bolts off the valve body. I counted 11 bolts and 2 nuts. (1993 Ford Bronco)

  8. Step 8

    Pull the old valve body out and slide the new one into place. Dmanic did not record the torque specs and instead ran the fasteners in finger tight, then snugged them down starting from the middle and working out to both ends.

    Pull the old valve body out, and slide the new one in. Sorry I forget the torque specs, but I usually put them in finger tight, then start… (1993 Ford Bronco) Pull the old valve body out, and slide the new one in.

  9. Step 9

    Fit the new filter and make sure it snaps in tight. Dmanic used a NAPA filter that comes with the pan gasket, choosing the long-nozzle version of the two styles offered and noting the short one appears to suit a shallower pan.

    Put your new filter in. this is the one I bought from napa. It comes with the pan gasket. There seems to be 2 styles of this filter%u2026 o… (1993 Ford Bronco) Put your new filter in. this is the one I bought from napa. It comes with the pan gasket.

  10. Step 10

    Set the gasket on the pan, line it up with a couple of bolts, and slide the pan back on. Run all the bolts in finger tight and snug them down from the middle out to the ends.

    I put the gasket on the pan and get it all lined up with a couple of bolts, then slide it back on. Again, putting all the bolts in finger t… (1993 Ford Bronco)

  11. Step 11

    Add about 4 or 5 quarts of transmission fluid, reconnect the negative battery terminal, start the engine for a few seconds and look for leaks. Shut it off and finish filling; Dmanic's took about 8 ½ quarts without draining the torque converter.

    Then I usually add about 4 or 5 quarts of transmission fluid to it, connect the negative battery terminal back up, start it up for a few se… (1993 Ford Bronco)

  12. Step 12

    Take it easy for the first few miles while the computer relearns the shift points, and allow about 50 to 100 miles for the new valve body to be in full effect, as the supplier recommends according to Dmanic. The last photo shows the finished truck.

    Take it easy for the first few miles, until your computer relearns the shifting points, etc%u2026 and Paul recommends you give it about 50… (1993 Ford Bronco)
