47RE 24v Cummins Transmission Band Adjustment and Fluid/Filter Change

[@garzadelagarza]

I had that same issue on mine for a long time after attempting everything in this video plus change the governor solenoid to an upgraded gm solenoid. What really fixed it was that I took off the whole valve body off and dissembled and cleaned it. I found a lot of the debris inside cleaned it and assembled everything back and fixed the issue on mine. This can be challenging because it has many small parts but it can be done with patience.

[@AllThingsBoost]

I had not considered that, I appreciate it! I think I will definitely give that a shot in a few months. Thanks!

[@ertreeservice9558]

The GM upgrade solenoid will make a huge difference! I did mine and my transmission shifts awesome now.

Any video ? Or guide you follow to remove the valve body

[@spencerstockwell]

i have a 2002 2500 with the 47re and it would stutter shifting from 45-50 mph, and after adjusting just the outside band the stutter is gone. thank you for the help 👍

[@toddg4258]

I have this issue as well, had my transmission built twice. One shop said it was ground issues, that the transmission was gear hunting. Kept all the grounds cleaned helped a little bit. Second rebuild was a full upgrade, which the torque converter was shot this time. They told me make sure that I have everything far as breaks and bearings working smoothly, because any resistance may cause drag and the pressure governor will had a hard time making transmission shift

[@AllThingsBoost]

Good to know. I found my particular issue was the TV cable being too short because a bracket was on wrong. Getting a built trans is eventually the go to though

[@TheHyde8875]

They're feeding you full of crap for a poorly built trans.

[@markrich3271]

Your throttle valve cable along with the throttle valve its self controls up shifts . You can find charts on line showing you how to adjust properly. Sonax makes a updated throttle valve that helps restore vacuum to the bore. One is a drop in and the other needs a reamer if it's really bad. Ypu also get springs and washers to adjust your shift points. A transgo shift kit is a must for any cummins owner .

[@AllThingsBoost]

Yep. When I did a built trans I found the root cause to the shifting was the TV cable bracket on the trans was backwards, making it get stretched about an extra half inch.

[@markrich3271]

@@AllThingsBoost That's great to hear. Our transmission are great when properly maintained. The amount of power they can take is amazing. I know for me when I was a young man transmission were a sort of a black art. They only way to understand them is to do how you did a just work on them. I'm happy you found your issue and corrected it. I love my second gen 24v.

[@BiffsEquipment]

You may want to also adjust your TV cable if problem persists.. if the cable is out of adjustment line pressure will be off And it would require you to let out of the throttle to shift so def check that

[@AllThingsBoost]

That's what it wound up being. When I swapped transmissions I found the bracket that holds the TV cable was backwards, spacing it out about an extra half inch making the trans think it was always under throttle

[@BiffsEquipment]

@@AllThingsBoost damn, well I’m glad you figured it out man. Soon as you said when you let out it shifted and it did the same for both 1-2 and 2-3 I instaintly said “sounds like the tv cable is showing too much pressure to the VB which is why the Rpms are going so high before it shifts” if it only did that in one gear I wouldn’t have thought that but because on your test drive it did the same thing for every gear it made me think that. Great video none the less! I just had to fix my truck yesterday, I was getting super low line pressure and it ended up being a clogged filter because of a brand new Tripple disk I installed about a month or so ago.. lots of break in material from the brand new Tripple disk and I didn’t know that when you install a new converter you want to swap the filter for a new one after a week or so of driving. Yesterday I was looking for a possible solution your video popped up and that’s how I wound up here lol.

[@tomtwiss8506]

Super helpful, I'm doing a fluid and band adjustment on a 02. Thanks for making the video

[@rgrg3683]

cable kick dwn. adjusts when to shift, early or late, bands is the shift smoothness or toughness, tighter bands and itl shift hard, looser bands will give you smoother shifts, too loose iy will slip, too tight it will hold back and shift hard up or down🤠👍

[@oldcroneysgarage9739]

Love that 24 valve sound!

[@hoosierfarmer3484]

[@johnnycash4505]

The shift link on the side if the transmission....mine was doing the same thing...adjusted that L shaped bracket .... and it changed the shift points

[@AllThingsBoost]

Yep, when I put my built trans in I found that stupid bracket was installed backwards by someone...

[@anonymouslegion728]

I ordered a Suncoast Diesel stage 3 rebuild kit for mine, comes with all the clutches, steels, etc and a billet input shaft, billet flexplate, and billet triple disk convertor. Have you thought about installing a shift kit in yours? I also bought the Transgo shift kit for mine to get the most out of it. One thing I would suggest is a Mag Hytec transmission pan if for nothing else it makes draining the fluid much easier. Great video!

[@AllThingsBoost]

Huh, I hadn't considered trying to build it myself. Thanks for the info! I'll definitely look into it

[@aidantrombley3767]

Have you thought about the governor pressure sensor and the solienoid

[@AllThingsBoost]

Went built trans from Dynamic Transmissions, very happy with it. This one eventually started losing over drive

[@CJAtrading]

Awesome vid dude helped me big. Straight to the point. Followed and liked.

[@alanwerhan5257]

Change the governor selenoid and pressure sensor,use the BD performance. Hardly ever the band.

[@paulharrington5746]

I am working on a 2001 dodge 3500 with v 10 magnum. wouldn't go into reverse. found issue with band going to adjust bands to hold the keepers in place, one keeper fell out and locked reverse out. I also have the high engine rev shift problem. So i decided to go with a Next Gen Diesel Heavy Load valve body, has all the upgrades. And adjust the tv cable in accordance to the shop manual. If you fixed problem let me know

[@AllThingsBoost]

My TV cable bracket on the transmission was backwards making it a half inch too short, so I had a lot of tensions on it causing my shift issue.

[@the_broadies818]

Did you ever figure out the transmission issue

[@AllThingsBoost]

Of all things, the TV cable bracket was flipped putting too much tension on it.

[@crenulatemist6531]

I would definitely take a look at your tv cable, seems like it may be too tight

[@AllThingsBoost]

I loosened it as much as the adjustment allows, but its possible. I wouldn't be surprised if it got shortened or remade in a pinch back by one of the previous owners. I'll probably revisit it soon. Thanks for the input

[@crenulatemist6531]

@@AllThingsBoost ok, I remember doing some work on my 99 gasser truck and I messed up the tv cable and it shifted like crap. Maybe try tightening some? Just play with it and see if shift quality gets any better

[@AllThingsBoost]

@@crenulatemist6531 oh yeah, so i jerry rigged some zip ties to lengthen the cable about .5" and it shifts perfectly now. Definitely something made my cable too short, so I really appreciate you pointing that out and making me revisit that.

[@crenulatemist6531]

@@AllThingsBoost absolutely, glad you got your truck figured out!

[@jasunsmith9136]

The tv is out of adjustment. I am sure adjusting or swapping the band helped, but the tv cable is the culprit here. Have only watched 1:53 of the vid so far.

[@AllThingsBoost]

Yep, I discovered much later when swapping out the transmission that someone put on the TV cable trans bracket backwards making it about a half inch longer than it was supposed to be. My temp fix before that was making it longer temporarily with zip ties.

[@KelliGrayoffroad]

I do the same on my 99 v10. Same tranns however mine does it from 2 to 3rd gonna guess not the same issue.

[@AllThingsBoost]

Interesting, I hope you figure it out

[@norbertorivera5106]

I have the same problem for my dodge please let me know what you did to fix it.. lm going to attempt to clean the valve body Thanks

[@AllThingsBoost]

Well, actually it's fixed now. I haven't made a video on it yet, but my TV cable was too short. Even at its maximum adjusted length it was still putting too much pressure to the trans. I temporarily used zip ties to make it about half an inch longer and it shifts perfectly now. I need to either replace the cable or come up with a more permanent way to make it longer.

[@norbertorivera5106]

@@AllThingsBoost thanks I’m going to try it 🤞🏽

[@liamaustin8123]

@allthingsboost how much transmission fluid did the 47RE take?!

[@AllThingsBoost]

I think it was 5 qts? Start with like 4.5 on the refill, start it, let it idle, then check fluid level, make sure it's on the dip stick, after that drive it, get it warm and check periodically until it's at the right level. Dont wanna over fill it

Yup. Found out later someone installed a bracket backwards, putting way too much tension on the cable.

Trying to understand these adjustments, sounds like a little too much slack in the TV cable, causes soft and late shift?
