Got 94f150 want go into 3rd gear fluid was dirty so I was gonna change that put 2 bottle of Lucas in it over about 6 months but i shifted fine when you get to 3rd gear makes a whining noise and want go into 3rd any suggestions thank you sir
my 94 e150 w 200k miles with the e4od just blew a front seal. ive never towed anything and the trans has never had any problems. all hiway miles. last fall i did the the trans service and it was clean, no debris and the fluid looked brand new. it is my understanding that the original seals were poorly designed and prone to failure. is it possible that this was just a seal failure? Is it common for the original pump seal to eventually fail with an otherwise normally operating trans?
Yes, i run a repair shop. The unit you have ...has had decent if not good service miles... Replace the worn seal...and many more miles of riding will be in your favor.
My 1990 f350 with e40d went to tow trailer kept jumping up on highway to higher rpm then back to normal ran out of overdrive. Can't figure out why shifts ok without 1500 lbs trailer any ideas thanks.
@@mdtransmissionspecialties I hope that youtube mechanic comment wasn't directed at me because i am anything but a bonafide mechanic, especially when it comes to fords which i try to avoid as much as possible on account i hate them but unfortunately i've been stuck with one which i try my hardest to take care of so i don't have to do any major work on it. with that said can you answer something for me, with the e40d being based on the c6 why under load does my e40d appear to have 4 distinct shift plus od, when not under load sometimes what seems like 3rd and 4th will slush together, did ford have a 5 speed auto in an f250 in 1992?
@@mdtransmissionspecialties i was afraid you were going to say something like that, i bought a kit with springs and shit that is supposed to firm the shifts back up but swapping out springs and things in the valve body is way past my experience level, except for filters and pan gaskets i've avoided the inside of A/T's my whole life, i guess i should man up and just do it, what's the worst that can happen......lmao thanks
@@shamrockperformance7180 Ive been building ford transmissions long time ive never seen trans fluid erode aluminum. The 4r100 center supports are not secured enough in the case causing them to rock which beats em up where they seat in the case. Thats what the .050 snap ring modification fixes.
Well then i was miss educated, thats just what they told us caused it at the wit trans seminar and it seemed to make sense due to that paths that eat out ,looks like water erossion in dirt
@@shamrockperformance7180 The E4OD core that I used for a build for my '79 Ford F350 to replace a C6 had a cooked forward clutch just like yours but the center support didn't have any significant wear. I reused it but upgraded it to the later roller bearing style. I didn't upgrade the planetaries either at first but I stripped the splines in the original aluminum OD planetary after about 800 miles after which I upgraded it to a non aluminum 4 gear set. Good video.
Thanks Luke. I was wondering why I was getting hard shifting in all gears recently. In Phoenix, we have been having heat lighting in the summer and having transmission problems. I'm thinking that it could be the grounding. Add ground straps to the transmission? What would you recommend?
Doing this video from a phone camera , is completely un-professional. The main stay reason why these fail are due to two primary things 1) Excessive heat- cure= transmission cooler(s) { I run two out in front of the radiator and don't have any issues} , I also have a trans temp gauge which will tell you, when things are getting to hot. The use of a thermostatic fan will also increase cooling. 2) Poor maintenance done by owners ; Change your ATF fluid at least once a year people!!!! Things you can do to slow this process down: Deep draft pan which adds more fluid and gives the fluid time to cool as it goes through the fluid circuit. Increased transmission cooler capacity; Jegs has those and if you need to add a second one, do it. I've run two coolers for years and never once had any issues.
Who makes the best rebuild kit for E40D in your opinion. I need to OH mine. Thanks!
i like the raybestous kits with gpz frictions the best

As a person with little experience, I found your video waaay over my head, and chaotic and confusing.

Great video -- don't care that you did it by phone. It's good information for us noobs.

Sounds like with the weight it might be slipping
thanks for the info. ignore the negative comments.
What info? The information of him not knowing shit?
Do you have an e4od to a 7.3 idi rebuild video?
Some people are too smart to teach.
i thought the e40d is supposed to be just a C6 with overdrive added, i don't recall C6's ever having the kind of failure rates that e40d's have...
Because no one takes care of anything anymore and everyone is a TH-cam mechanic. It’s a c6 from the intermediate clutch back.

@@abruptlyblunt you where correct on the c6 part. The reason it feels like you have 5 gears sometimes is you’re feeling the torque converter locking.

@@abruptlyblunt I have a transmission shop. You can send me your accumulator and I’ll install your shift kit
Did you say the fluid is eriding the center support?? Ummm no 🤦♂️
Yes i did say that because thats what happens to every e4od and 4r100 very common problem

I've heard bad grounds can cause current to travel through there constantly generating heat... Not good

Great vid, thanks!
Also, Once you take off shifts through all gears fine.
Dude. You’re all wet.
Not much. of a help to me. Maybe you're talking to people who already know about transmissiins
trying to do video with your phone??? really???
He probably wouldn't be doing it otherwise so... Gratitude
