Just what I wanted to hear. Thanks!

That's what I NEEDED to hear, lol. Thanks again. When you say fine sandpaper, I'm thinking 1500+ grit and maybe some trans fluid or oil?


I had planned on doing the Transgo HD2 kit. Overkill for my limited towing?

Thanks again for your recommendations, and the good news on the pump. If you were close by, I'd buy you more than one drink, lol.

 

Here's what's been ordered so far:

6P front planet and ring gear shown above
6P rear planet
New sun gear for the shell
Front drum with new backing and apply plates and belville spring
Machined center support with Sonnex snap ring
Transgo shift kit
New Ford cooler bypass tube - was only $6 more than the rebuild kit

Transmission rebuild kit - this is the kit I'm looking at. I'd much rather have the Kolene steels, but with the extra hard parts I'm having to buy, I can't go that route.

Diode to sprag conversion - there's nothing wrong with the direct drum, other than being the mechanical diode drum. Anyone have any concerns or experience with this kit? Good or bad?

For cleaning everything, I'm using mineral spirits, but I'm not sure I got the right stuff. Walmart was out of mineral sprirts, so I went to a hardware store. All they had was Kleen Strip Green - this stuff is white, with a consistency close to milk. Anybody know if this will be okay to use on transmission parts?


Thanks in advance for any recommendations,

Brian

 

I’m throughly enjoying this thread, thanks for putting it together. I’m currently rebuilding a ‘91 and swapping many parts from a 4R100.

Does the new machined center support you found come with the roller bearing pressed in? I want to get a new center support but I can’t find any online that comes with the bearing installed.

 

Thank you. I hope others are learning as I am. I was hesitant to try this rebuild, having only done three other transmissions previously. The interesting parts will be when I install the Transgo shift kit, tho. Disassembly and inspection is fairly straight forward.


If you're rebuilding an E4OD, there's a lot of options for improvement with 4R100 parts.


No, I just bought the machined aluminum support, as the steel support section with the roller bearing is still in good shape, though I may decide to change it out anyway since I'm replacing so many hard parts already. You can get the steel section from the Transmission Bench with the bearing installed, or numerous sources on eBay. The machined support I got, with the Sonnax ring was $50.

 

That kit seems to have everything you will need, does it come without that shift kit?

Because the shift kit I linked https://transgo.com/product-details/sk-e4od/ has the accumulator springs, <acronym title="Page Ranking"><acronym title="Page Ranking">PR</acronym></acronym> spring and boost valve and the spring for the converter clutch. That kit just has steel replacement valves which is good but the springs in the other kit really make better and it has a steel valve for the only one that ever has a problem. Maybe you plan to have both kits which is fine just thought you could cut the cost down a bit.

I have never used that or any conversion kit for the drum but I do find it interesting its converting the diode style drum to a sprag style drum and not selling the sprag with the kit, good thing your overhaul kit is including it and it should for that price.

I am not familiar with Kleen Strip Green, as long as is don't rust your parts and cleans well it should be fine. We use straight mineral spirits for things like the valve body and electrical and small items and part washers for the other stuff.

There is a metal ring that sits on the forward piston under the bevel spring, I saw in one of your pictures it was out of place and might be damaged. I didn't see it listed in the replacement parts for your forward drum stuff.

It supposed to sit in the groove in the piston and the fingers on the bevel spring ride on the ring, yours looks stretched out and out of the groove in this picture. I highlighted what I am referring too.

 

Hi James,

Unfortunately, it does not. I figured worst case, I'd just list that shift kit on eBay. The kit that doesn't have the shift kit, also doesn't have the Torrington bearings, either.


I was leaning more towards the 4R100HD2 Transgo kit, honestly. Though I haven't fully made my mind up - so it's not been ordered yet. What are the advantages of the kit you listed, if any over the HD2 kit?


Yes, the 45 element sprag is included, that's why I went that route. I anticipated buying a new direct drum once I found out I had a diode transmission. I didn't anticipate all of the damage - I had hoped the symptoms were related to loose fluid feed bolts. I'm really hoping this works out well. Like any other salesman, the guy I talked to said he sells them every day and has never had any complaints. I've seen them advertised on a couple of websites, and appears to be a Transtar part. So I guess in this regard, I get to be a guinea pig for the FTE group, lol.


I've washed a couple of the bad parts in the stuff, just to see the results. So far, no rust.


That ring is included in the parts I ordered, just forgot to list it. Thanks for keeping me on my toes! All of the hard parts should be here Friday, I'm looking at next week for the rebuild and shift kits. Then a new cooler, torque converter and solenoid pack... yeesh this is expensive...

I'll be taking lots of detailed pics of the new parts as I start to reassemble the transmission - and I'm not going to be in a huge hurry to git 'r done. I want it done right. Which is why I'm asking so many annoying questions, lol.

Thanks for all your help and advice!

Thanks for the link. That's what happens when I try to go off memory; it fails me. I was thinking the steel support was pressed into the aluminum center support. Also, Jimmy Williams from the Transmission Bench is excellent to speak with during your build. I've called him on the phone a few times when I was building a 4R70W. I can't thank him enough.

 

I'll be adding some more pics later, but this one annoyed me.


Little dinged up.

More dings...

Couple more...

Got this forward drum off of eBay with the piston, and apply and backing plates. The image that was shown on the item description didn't show these dings. Nor did it show a broken dealing ring that was also worn down to half its original thickness. I'll post pictures of those sealing rings, and the grooves later. The grooves look ok. I'm not a fan when sellers don't post good descriptions and detailed images. Only reason I went ahead and got it was they had good reviews and a 100% rating.

I'll be contacting them shortly.

 

Well, I promised a few more images of the parts I've received so far. Have replacements for the forward clutch drum, ring gear and planet, as well as the rear planet.


The original forward planetary, on the right, is basically destroyed. Figured if it needs replaced, I was going with a 6P version.



Original, on the left this time, has as many missing teeth as a meth addict.



Rear planetary on the right. There's really nothing wrong with it at all. Just couldn't see NOT replacing it with a steel 6P version while the trans was apart.



Original ring gear, again on the right. I've tried a mechanics pick and other tools to remove the needles from the failed bearing - ain't happening.



From the outside, the original forward clutch drum appears fine. Slightly better than it's replacement. Main difference being is I wanted to move to the full spline bore, even though the V10 may not necessarily need it.



This picture tells the story. The original on the right has been peened all over by the needles from the failed bearing. This drum is probably still usable, with just a little work with a stone to remove any sharp edges.



This is the forward clutch piston, original on the right. You can see how badly damaged the piston bore is. Then check out the ring the belville spring rides on.

The rebuild kit will be in some time next week. Apparently the HD 45 element sprag is in short supply right now... Until then, I'm cleaning parts, watching videos and re-reading the ATSG manual.

 

You probably made a good call getting the fully splined forward drum. I purchased a new HD 45 lug sprag last night and it was shipped today from this eBay vendor:

https://www.ebay.com/itm/4R100-E4OD-...72.m2749.l2649

 

Since I've got a diode transmission, I'm getting the direct drum conversion kit listed in an above post. Coming from Trans Parts Warehouse in Cali, and the sprag is included in the price of the rebuild kit, so I'll be patient, lol.

 

Started cleaning a few things, this was the nasty part:


Looks like death of a transmission



If you look closely, you can see where some of the needle bearings from that destroyed Torrington ended up



All clean now. Had to use some emery cloth to remove rust from the outside edges. The magnet was pretty tough to get all the metal off of - duh...

Also have the separator plate cleaned. Since I'm waiting on the reabuild kit still, tomorrow I start the accumulator and valve bodies. I'll be installing the Transgo 4R100HD2 kit since it was available locally. Have a few holes to drill here and there, but looks fairly straight forward.

 

My advice is to not install the drum conversion kit. I rebuilt my 2001 4r100 this summer and initially installed the conversion kit. It made it 1.5 miles before the the sprag gear was destroyed. I'm still not sure what happened, but it appeared to be a lack of lubrication. I had to pull the transmission again and replaced the drum with a non mechanical diode version. All has been fine since then.

 

That sure as hell wasn't what i needed to hear...

 

Believe me, I wish someone had told me before I used that kit.
On the plus side, I was getting really good at taking the transmission in and out of my truck...
