E4OD and 4R100E Troubleshooting     List of Categories

Page 1 Page 2 Page 3

  1. 1993 E4OD works only when I turn the OD off or put it in 1 or 2. But is sluggish, once I get it going I can go back to OD untill I stop again. You got any Idea's?

  2. I have 1990 4x4 bronco 5.8L, I just had the tranny rebuilt and got a new engine kit put in. i hoped it would solve my problem from before but it has not. I keep getting a shuddering and lack of acceleration when I give it gas in nearly every gear it seems like. I have no idea what it is and would appreciate the help.

  3. i replaced front pump seal but im still leaking fluid just as bad what else could it be

  4. i have a 1996 ford powerstroke.no forward or rev.at all.in P,or N it idles down.but in any other gear it idles up.just the opposite as it would normaly idle.I was told it may be an electrical issue.any help or suggestions would be greatly apreciated.thank you.

  5. I have a 93 F150 with E4OD tranny. When I put a load on it going up hills It gives me a shudder. Talked to a mech and he told me engine problems can cause the shudder also. I do have a code 327 for the EGR system. Never heard of engine problems causing problems with the trannie like that. When just driving without towing anything or putting a load on I have no problems with shifting. Shifts as smooth as any other Automatic I've ever driven. Any truth to the Engine causing that problem? Thanks.

  6. My 1990 F250 automatic w/overdrive has suddenly decided not to start in park or move in reverse after a 160 mile trip. After driving 80 miles non-stop, I pulled up to a light and stopped. It didn't want to take off, but finally caught hold and did. I could no longer start with the key, so bypassed with a starter button. We returned the 80 miles fine, or so we thought. We had not tried to back up and discovered that it won't move in reverse. Any suggestions or thoughts on the problem? I did try loosening the linkage and move it by hand, but still could not find reverse.

  7. i have a 99 ford f250. i was wondering if a torqure converter going out could render your transmission inoperative?

  8. I have E4OD auto trany in 90 F150 4x4 4.9 6 cyl. Will only drive in reverse. Drive and 2nd, no response. 1st gives lite engagement, but will not role truck forward at all. What could possibly be wrong?

  9. I have an F-350 1 ton dually with the 7.3liter diesel. My problem is the person who owned it before burned up a transmission had it rebuilt. I bought it and 20,000 later every time I went to pull with it the transmission would pour out oil from the bell housing. Three seals later, we assumed maybe a warped case so I replaced it with a whole new remfg transmission and new oil cooler and lines. Well 28,000 miles later I have oil pouring out of bell housing every 2 or 3 rides, just driving not towing? Dealer canít figure it out? I love the truck but NEED a fix!

  10. I have a 93 Coachman RV equipped with a 460/e4od tranny. When moving along slowly in OD, the tranny to have difficulty deciding whether to be in OD or 4th; seems to shift back and forth. Is this normal or am I beginning to have a problem? Only 66K on the whole outfit.

    You have a damaged (overruns both ways) Overdrive one way clutch. All the power that comes into the transmission in first through third gears comes in through the OD one-way clutch. There is also a coast clutch that will perform the same function as the OD one-way, but it is only intended to provide engine braking. Since it is only meant for engine braking it is a very small clutch pack and does not perform the work of moving the vehicle forward well, that is why you get the sluggishness. The coast clutch is only applied when OD is cancelled, or manual first or second is selected. This is why your transmission works under these conditions. In OD normal operation is that the coast clutch is off and the OD one-way is overrunning, therefore, OD works normally.

    When the transmission was rebuilt, was a new torque converter used? If not, a bad torque converter can cause poor acceleration and shuddering. Also check to make sure there is no bind in the transfer case, and make sure there are no problems with your PCM or fuel delivery system that may cause the poor engine performance. Pay very close attention to all parts that were reused after the rebuilds.

  3. i replaced front pump seal but im still leaking fluid just as bad what else could it be

    It could be the seal or gasket between the front pump and the case, or you may have a bad drive tube on the converter that is damaging the seal. Check the surface of the converter tube that rotates inside the seal for nicks or burrs.

  4. i have a 1996 ford powerstroke.no forward or rev.at all.in P,or N it idles down.but in any other gear it idles up.just the opposite as it would normaly idle.I was told it may be an electrical issue.any help or suggestions would be greatly apreciated.thank you.

    No electrical issue can result in a complete loss of all gear ranges. Electronic transmission are designed this way so that in the event of an electrical failure you can still get the vehicle to a safe place to park. The reason the idle increases in gear is because the computer increases fuel when it expects to see an increased load on the engine in order to provide a consistent idle speed. Since the transmission is damaged it is not loading the engine, therefore the idle speed increases. The strategy is to essentially keep the idle speed about the same RPM whether the engine is loaded or unloaded. Things that could cause this would be a damaged torque converter, broken input shaft or OD planetary, or a damaged OD one way clutch. If the OD one way clutch is damaged then you can often get the gears to work by cancelling OD or choosing first or second manually. If you can't get movement this way either the OD one way is probably good, but you may have damaged one of the other parts mentioned. This list is not all inclusive, but it does contain the more likely culprits. With the diesel engines, the splines tend to get beaten out of the aluminum OD planetary carrier, which can cause all of your symptoms. If you want to upgrade during your rebuild you can use our E4OD hard parts update kit listed in our E4OD products section.

  5. I have a 93 F150 with E4OD tranny. When I put a load on it going up hills It gives me a shudder. Talked to a mech and he told me engine problems can cause the shudder also.

Any truth to the Engine causing that problem? Thanks.

    It's not that the engine problem causes the transmission problem, it's just that engine problems can easily be mistaken for transmission problems. If you have a shudder under load it could be a problem with the converter clutch, or it could be due to a problem with the EGR system causing the engine to misfire under load. If the converter clutch is unlocked and slipping the converter slippage can mask the misfire, and when the converter locks the misfire is noticable because the converter slip is gone. I would definitely take care of the EGR system first since it can cause misfires, and is likely to be much less expensive to repair than a transmission problem.

    There is nothing electrical about reverse so you are going to need a rebuild. It seems like you also have trouble with your range sensor, which could have contributed to the failure. After the rebuild be sure to have all of the sensors and wiring checked.

    If the torque converter was damaged significantly it could result in a loss of all forward and reverse movement.

    It sounds like your forward clutch may have gone out, or you may have stripped out the splines from your forward planetary. It looks like you are going to need a rebuild.

    It sounds like your E4OD is overheating. You can try adding a bigger auxillary cooler and maybe a deep pan. It is common for the E4OD to push fluid out of the front seal when it overheats. It could also be overheating due to slippage if there is some other problem like low line pressure.

    Actually fourth gear is overdrive. What you feel coming in and out is probably the converter clutch. It sounds normal, but I couldn't be sure without riding in the vehicle.
