[Edit] Explained my question literally 10 seconds after I paused it. Great video.

[@Canvideo]

Good video, Thanks. I just worked on a 42re for the first time. It had the direct clutch snap ring broken, so when taking this unit apart, the inner round snap ring was not removed as I didn't know it was there until I saw your video, so things looked different than in your video as this round snap ring kept the spring compressed. Assembly was without a press, I used a floor jack and a round wood block on the top to compress the spring. I also did not have a spare splined shaft to align the splines so I used the output shaft.I had no room to keep the shaft in place to compress so I found out that when compressing the spring, it twists the spline and could not re-engage the output shaft. By turning the drum about a quarter of an inch on the outside radius after pulling out the splined shaft compensated enough to have them lined up after the spring was compressed and snap ring installed.

[@adamdanner2702]

Nice detail. I have a crazy question about an idea I have. It seems possible that one could built a stand alone overdrive unit out of this 48RE overdrive by adding a custom front cover along with a converted transmission shaft that your stub shaft is made from. Add a oil pump along with a shift solenoid. Does that seem plausible?

[@dannycassell4128]

This video is very detailed and informative! It allowed me to swap overdrive housings from a 4x4 to a 2x4 transmission! Thanks very much for posting such a great video!!!

[@xxRamD3yruxx]

Danny Cassell what all did you have to do? thinking about doing that too.

[@CascadeTransParts]

all 4.7L models are 45RFE or 545RFE's which take the same filter kit depending on 2wd or 4wd , we have them listing on the site in a kit form. Our kits include the cooler return filter , and pan gasket. As far as the solenoid , your model contains a solenoid block which is all in one assembly - also shown on the site Hope this helps further questions direct through the website contact us page

Thank you for your video,you seved me a lot of hours of work

[@Natedoc808]

Thanks for making this video, it was very very helpful during the rebuild as the press procedure to remove the two retainers was not clearly outlined.

[@chadlariviere6240]

Great video...I have a 2000 dodge dakota 4x4 had to slide the transfer case and the drive housing so I could remove the pin for the reverse servo piston arm..now I am having a problem with getting it to spline back together ...any advice you can give

[@greygoosemafia]

im looking at a complete diy lol trans repair. I hae a 99 ram 1500. can you tell what trans I have? I got the early failure code. said trans shop. can you tell me what that means exactly? what you would expect to see in tha type of situation? rebuilt back in 2011

[@Alpejohn]

A friend of mine with a Dodge Ram 2500 04 model, just lost his reverse. After removing the oil pan he found several pieces that looks like the wave ring/lock ring. I read in a forum, one dude claimed that when this ring comes loose you will loose reverse? Is that correct? Also, is it difficult to change it? Any special tools needed? Or is it just to remove the OD unit from the car, and apply pressure to loosen the ring, then get out the rest of the pieces and then add the new ring in place and release pressure? Or do we have to center everything when doing this? (By using a shaft through the pack?)

[@Quadman808]

the broken snap ring is very common, our part # 12864 www.cascadetransmissionparts.com/46rh46rewavedsnapring.aspx it requires rebuilding the rear overdrive section, we do manufacture the special tools to rebuild it - all items on our site to rebuild it also www.cascadetransmissionparts.com/cascadeodcompressiontoolkit.aspx additional questions should be directed thru our email: [e-mail] Hope this helps -

[@geartech3860]

U need an H press and a overdrive alignment tool.

[@servantofyahuwah2486]

I rebuilt my 48re transmission but got something wrong, hoping you can tell me what it is. After rebuilding it, i drove it down the road a few miles and it did good, but suddenly it looses 2nd, 3rd, and overdrive. It is like it got put into nutral. When this happens if i shift into nutral for a second and shift back to drive it works again for a mile or so, then does it again. Would this be a sealing ring, seal, or would it have to be in the vavle body? Thanks

[@CascadeTransParts]

our shift kits include install instructions with them. there isn't much in the kits that would correct a non shift overdrive more than likely the overdrive direct snap ring has broken please direct further questions through our site

[@CascadeTransParts]

to clerify it is loud , and creates a shudder feel ? can you verify if the sound comes from the front or the rear of the trans at just a guess it could be the converter , but typically that would be very mild vibration and as it continued it could get progressively worse. it you would consider it a shudder check out shudder fix on our website under the chemicals tab - often it can do miracles to some of these issues please keep in mind this is just a guess - tough to trouble shoot this way

[@randy1ization]

Hello wanted to c if u can help me out i changed valve body on my jeep 42re now shifter wont go to P have to crank in N i dropped oil pan twice allready thinking it was pawl lever not set right do u think im still not setting it right ?? I would really appreciate your advice thank u

[@matthutch4216]

I know you made this video a long time ago. But I recently did a filter change on my 42re and the magnet in the pan caught 3 pieces( about 9 inches) of what looks to be one of the retaining snap rings My question is can chunks of those move through the the trans to the pan with blowing up the trans. My truck is holding it's gear until it's at 3k and I have to let off the gas for it to shift from 1-2

[@geartech3860]

Your 1-2 shifting problem most likely has nothing to do with the overdrive snap ring.The pieces of the snap ring are heavy enough that they settle to the bottom of the pan,in most cases. Your problem is in the valve body or front band.

[@weaksrt4]

I bought a OD unit from the local tranny rebuild shop and it won’t go all the way on. As you mentioned in the video the splines need to be lineD up. Sure enough they aren’t. Can I align them at this point or does the 600# spring need to be decompressed and the alignment tool installed or can I align them without the tool and everything installed?

[@Quadman808]

if it won't slide all the way on then the splines are not lined up on the OD Inner Sprag race & the OD Planet. the only way to realign them is to recompress, align then uncompress try to handle it easy or better yet leave shaft in it until ready to install

i have a overdrive problem. when i'm driving i get a hard jolt and my overdrive stop working then it jolts again then it starts working again. but sometimes i have to turn car off and turn it back on for it to work again. can you give me any advice please.

[@joannladybug7772]

if that wavy snap ring is broke what should you do looks dangerous if it is broke

[@rhntrWOOHOO]

If I’m just replacing the housing is it necessary to release the retainer ring and use a press to remove everything? It’s a 46re on a 97 Dakota.

[@geartech3860]

No just swap

[@felipevalles8041]

I lost reverse, can I just buy a whole OD unit and replace it, I saw a rebuilt ones at Ebay for $250-$300 ,thanks 👍🏻

[@Quadman808]

reverse is not inside the overdrive section, maybe your low/reverse servo ...... that sounds like a great price for an OD though i be suspect as the rebuild parts alone are half that cost +

[@5BobbyDavis]

I just took an overdrive unit off a 42re and some of the lugs on the case where the little retaining spring(wire) holds the 4th clutches in are broken off.Any ideas on what caused this?

[@blashyrkhification]

[@geartech3860]

Yes you can.

[@chadevery1325]

Help I can't get the overdrive and transfer case to line up to the transmission. is the park rod in the way?? I put it in neutral. help

[@bryanhauschild4376]

what does the stub shaft do? do i need it if Im only swapping housings?

[@CascadeTransParts]

Hello- anytime the spring is expanded and recompressed the shaft tool is needed : the shaft keeps the alignment between the Overdrive Inner Sprag Race and the Overdrive planetary, this will then allow the OD Unit when reassembled to slide all the way onto the transmission. We offer the tool here in the below link - www.cascadetransmissionparts.com/cascadeoverdriverebuildtool.aspx Hope this helps

[@CascadeTransParts]

the overdrive inner race , and the overdrive sun gear need to aligned did you happen to use a shaft to line it all up when it was in the press ? we have some here if you need one , they are $29.00 email me through our site if i can help further

[@allianceofsteel]

getting ready to redo a 44re, now I've read and done some research but can you swap the innards from a 48re into a 44re housing, I know you can do a 46 re, but what if I wanted to go super heavy duty just because? I'm having a pro transmission guy do the work, he runs professional dragsters and has built a ton of these transmissions, just need to know for myself what swaps and what doesn't. I heard they are all the same case with different innards.. but who knows.. which information is real or not.

[@xxRamD3yruxx]

Tim Vincent no, the 48re is an a518 or TF727 derivative the 44re is an a500 or TF904 derivative the 727 is larger than a 904 so parts and clutches are mostly non transferable

[@allianceofsteel]

thank you for taking the time

[@xxRamD3yruxx]

no problem, although its a bit late.

[@allianceofsteel]

yeah car has been sitting since... just this payday will have the moola to take it to get "regutted"

[@CascadeTransParts]

2003 for the most part was a split year the easiest way would be with the casting # on top of the overdrive unit for 4wd models: 19104 would be a Late 47RE 44577 would be a 48RE

[@dakotak8437]

Where is the over dive snap ring located for 2001 Dodge Cummins 3500 thank

[@mariomartin1981]

why not make the job easier by removing the entire OD core by releasing the snap ring at the back of the extension housing,you have way more room to work on those c clips,the job is dangerous enough without having to go fishing with your fingers inside the housing,so much easier the other way.

[@geartech3860]

Those were my thoughts exactly.

Skipped a few steps, for some one thats never done this before they need to see the whole process step by step,especially the part where you assemble and recompress the spring again. you showed it already done and explained it backwards.With that dangerous spring in question you want to make sure your thorough and specific.

why do these transmissions have so many friggin names?

[@Quadman808]

its like that with almost All the entire line up of Automatic Trans & Transaxles the main reason is our industry calls it one type, but the Oem's & Dealers call them something completely different. Many parts interchange on the older applications like the "RE"'s but Boy is it insane the new 2010+ stuff they're changing trans type every 1-2 yrs and parts don't interchange
