How To Rebuild A Transmission 47RE Part 4 Overdrive Rebuild

[@danriceman7533]

You definitely make it look easy enough to make me think hard about doing myself when the time comes instead of spending the many thousands Suncoast wants. I'd be a little nervous sticking my fingers inside that PVC pipe under all that pressure in the press though...lol

[@ChadMyers73]

It is easier than I thought it would be and trust me it was is in the back of my head also. Lol

[@jwronkow]

Thanks for the Video. I am doing my first 48RE and so far your explanation of measuring the overdrive clearance was the easiest. Been trying to figure out how to do that without buying the tools. The only thing I didn't see you explain or show how you measured it was the intermediate shaft clearance to see if you needed a new spacer on the intermediate shaft? How do you measure that without the tools. I have the same intermediate shaft; however, I had to change the overdrive housing so I want to make sure that I have the correct intermediate spacer on the shaft.

[@ChadMyers73]

Are you talking about the spacer on the Extension housing end of the intermediate shaft?

[@jwronkow]

Yes, the c clip looking spacer, (color coded) on the end of the intermediate shaft that goes into the overdrive housing. Thanks

[@ChadMyers73]

I did not have a video on that it’s was done at a trans shop. Sorry

[@destinnewlon1957]

The material has the slashes in it to push fluid out of the way during apply so you don't have any slippage

[@ChadMyers73]

👍

[@c.s.outdoors2873]

What happens if you knock it out of alignment? Do you have to disassemble it? Is there a trick to help get it back in?

[@fredshipp3809]

Another excellent video Chad. I think you are doing a fine job on the assembly and explaining what you are doing.👍 I'm glad that PVC didn't fail when you were putting that snap ring back on the 800# spring. That would have made some sore fingers for sure.

[@ChadMyers73]

Thank you! Yes it would have that was in the back of my head when I was putting that back together...

[@lonnielawson2800]

What i need to know is how do you get it mated back on the main case ..i had trouble getting everything lined up ....i need a video ...

[@ChadMyers73]

Are you trying to put the overdrive housing on with the valve body in place?

[@21bkier]

Took mine off and it did not have that piston, just bought a new one and it doesn't have that piston...is it necessary?

[@beardedgaming1337]

nice. pretty sure i snapped my output shaft today . looks like a few hours to fix

[@ChadMyers73]

Yes it is.

[@beardedgaming1337]

@@ChadMyers73 what do you think about keeping a stock output shaft as a fuse? If I upgrade to a Billet would I be more likely to destroy my Billet input or intermediates?

[@ChadMyers73]

Yeah you could do that most intermediate shafts will hold up to 700hp

[@beardedgaming1337]

@@ChadMyers73 im thinking im around 800. compounds with 350 injectors and bored block. the only non billet part of the trans is the output shaft and ive kept it as the 'fuse' but... ive broken it 6 times now

[@ChadMyers73]

I would say upgrade it then.

[@coalstang]

How much did you have to machine off that one plate to get more clutches in the overdrive? I see you remove the wavy snap ring but was there much some machining you did to that thick steel?

[@ChadMyers73]

Sorry but I’m not sure that was all provided to me in my kit from firepunk.

[@coalstang]

@@ChadMyers73 OK no problem. I guess a guy could just machine his original pieces down until you get the proper clutch pack clearance.

[@ChadMyers73]

@@coalstang Absolutely

[@bmanj5435]

I was wondering if you knew if the clearance suggestion will work on the 48 re also I had .080 and added two shims to make it .110

[@ChadMyers73]

If your talking about the overdrive apply piston shim that has to be measured for every transmission.

[@bmanj5435]

@@ChadMyers73 yes I did I was just checking if the spec were the same as a 48re thanks for replying !!

[@ChadMyers73]

The measurement process is the same.

Your welcome best of luck

[@stephenpinckard526]

Where did you get that stepped plate for the overdrive brake assembly?

[@ChadMyers73]

My kit came from Fire Punk

[@larrymerrill2835]

How hard would it be to convert a 2wd OD unit to a 4wd unit? Just the shaft? I am looking at converting a 2wd 47re to 4wd.

[@johnshaver9042]

Shaft and housing are the only difference i’m pretty sure. If your still wondering lmao

[@chute2thrill1]

I tore my 48re core transmission apart.The overdrive unit was a bitch to get off.Intermediate shaft is stuck inside the overdrive.Where I bought it they said it had no o/d that is why.But I proceeded to take the rest it the transmission apart that way eventually I got it off but shaft is stuck in o/d.Guess I have to take it to a transmission shop and get them to get it out.Ever have that problem?

[@kennethcheesbrough6855]

My intermediate shAft is the rear clutches I cant get that apart and their is no transmision shop where I live nearest one is 200 miles.

[@tylergilbert2882]

All of those clutches have a notch in them but one. Is that okay? Cause some videos I’ve watched they are all notched but others there is just the one clutch that doesn’t have a notch in it.

[@ChadMyers73]

Not sure I’m following

[@thefogisgone3662]

How vital is that machined spacer when leaving the wave out?

[@ChadMyers73]

The machine spacer is for the added friction and steel

[@thefogisgone3662]

@@ChadMyers73 yeah I think they put the groove in it so it will seat on the regular snap ring when you leave the waved out so that you don't have to worry about excess play in the snap ring groove and it possibly coming out. I was gonna leave the wave out on mine and add a clutch and steel but then I realized I didn't have the stepped plate so I decided prolly not the best idea to risky. Thanks bud

[@ChadMyers73]

Yeah you have to have that milled to do that. Firepunk sells them with exchange

[@thomasderush5180]

Not sure why you guys are not checking the plate the giant spring rides on, it is supposed to spin freely on the overdrive sungear, if it doesn't it's worn and need replaced

[@ChadMyers73]

👍 Thanks for the info

[@koioo2]

we are in 85 to 90ts in 2 days cool down and don t ask me to do this no way I can do it but I did notice when you put parts together and the press was no push no rush so best advice be don t force it don t push it take your time

[@ChadMyers73]

Absolutely!!!

[@mikegimenez2629]

100% incorrect way to determine the O/D clutch piston spacer. There are special tools made to do the job correctly, also how do you know the intermediate shaft spacer ring is the correct one.? That is important, because the final endplay adjustment relies on a correct intermediate shaft spacer measurement. I've rebuilt plenty of these since the first came out.

[@ChadMyers73]

That prybar is the same thickness as your measuring tool that you purchase I believe it’s 6311 if I’m not mistaken, and that came from the ATG manual. For intermediate shaft spacer I took it to a transmission shop and had that measurement determined for me. While I was there, he checked my ring spacer measurements just to double double check me and he said I was spot on.

[@claymcphaul0356]

If that PVC let’s go in the press, you could lose a finger.

Trust me that thought was in the back of my head.....
