47RE bands???????

[JARichard]

I have an 03 service manual. The manual has instructions for the following transmissions 45RE 46 RE & 48RE. It gives no description of the 47RE. What model am i to use for info on the 47RE? There is a 2 turn difference in band adjustment from the 46 RE to 48 RE? Any one know what the adjustment is for a 47 RE? And does your 03 service manual have the 47RE section

Thanks!!!!

I know that I have a 47RE. The service manual I own has no section for the 47RE. My question is am I s'posed to use a different model in the manual for the 47RE or did they just not add that section to my manual? Do you know the proper adjustment for the 47 RE?

You wont find bans out of adjust. Only adjusted in a overhaul. Its in the shop manual but any GOOD trans man will tell you thats B. S. and only done at rebuild time. There NEVER out in a healthy trans. Usually only ones trying to adjust them are in the backyard. I know I'll get some static on this but its the truth.

I don't agree with that last statement of not ever adjusting your bands. I fell into that category... I waited until my transmission had problems... by the time I adjusted it, it was too late. I now plan to adjust the front band at every fluid change, especially since I'm spending $4500 rebuilding the thing (man billet isn't cheap )... so I'm going to do everything to make it last as long as it can. The front band is easy to adjust because the pan doesn't need to be dropped.



To adjust the front band, loosen the lock nut, torque the band adjuster to 72 inch lbs, and back it off 1 7/8 turns. I back mine off two turns because it seems to tighted a tad when I cinch the lock nut back up. The procedure take 5 minutes and can be done as frequently as you want with no harm to the transmission, just might be wasting your time if you do it too often.



The rear band is a little harder, but simple once you get the pan dropped and the filter off. I will probably only pull the pan every other oil change or so, but the rear band can be adjusted less freqently because it wears slower. Use the same procedure as above, but back it off 3 turns.

Is that 1 to 7/8th's of turns or 1 7/8th's of a turn.

I knew I'd get static on that post but went through that in the first generation forum. Until the trans builders gave comments. There NEVER out until its torn up. If any ban is ever out its the rear but that dosent much if ever happen eaither. Ask good TRANS builders. They'll tell you the same thing. I worry more about do it yourselfers doing damage by attemting a adjustment much more then the fact the adjustment is never needed. I will say no more then it dosent need to be on a service menu,causes more questions then it does good.

JARichard the '03 shop manual has 3 parts ... the main manual ... volume 2 which was wiring ... and a supplemental volume which covers just the 47re ... when i ordered my manual i got all three for 87$ from the dealer ... hope this helps

 

[JARichard]

2broke do you know if the 03 manual was s'posed to be in 3 parts?

 

[2broke2smoke]

yeah ... that's exactly what i'm saying ... i just ordered it from dodge and got 3 books ... if you want i could scan and send you the page on how to adjust the bands but jeepdude hit it right on the money

Explain this statement. Unless you can't follow directions or use ft-lb instead of in-lb, I don't see how you can mess anything up by adjusting it. Bottom line is that everyone has their own opinion and is free to maintain their vehicle in their own way. Personally, I have talked to and verified with more than one GOOD transmission builder this WON'T hurt anything. I would venture to say these guys know a LOT more about trannies than either of us. One other question... if adjustment is NEVER needed, why is it there?

I lost reverse in my 68, 383ci, 727auto Dart. A freind and transmission guy told me to adjsut the rear band before pulling the transmission. I did and it worked!!!!!!. Although it only worked for a couple of months. If I would have adjusted it when I put the transmission in to begin with it would have lasted even longer. Nothing wrong with adjusting things that are designed to be adjusted.

If you have to adjust your bands on a 47, then there's big problems. Anyone who has had the trans apart and has seen the band will know this. There's just no great amount of material there to begin with to allow a major change of adjustment from wear... .



If it requires a major adjustment, it's smoked.

Enough said Caratchko!

I agree, if it needs MAJOR adjustment then it's probably smoked. . because the little adjustments weren't kept up with along the way!



I understand your point, and while it's true that most of the time if the band seriously needs adjustment the transmission is close to rebuild time anyways, and adjusting the bands is not going to magically make your transmission last twice as long, I stand by the fact that regular adjustments WILL extend the length of time your transmission goes before having to be rebuilt. It may not get you another 100K miles, but even if I only got another 10K out of it, I see NO negatives or downsides to doing it.



I guess we'll just have to agree to disagree...

 

[curatchko]

Just for the record, I can't remember the measurement, but the material on the band isn't much thicker than 2 pieces of paper...



Nope, I don't see any negatives either... . and no point in trusting the original setting from the factory. Couldn't hurt to adjust it once just for a check-up.

I never even changed my original transmission fluid in my 47re. Engine was stock. Never had any trouble with Engine or transmission, until it's sudden departure from service.
