47RE In-chassis Upgrade Recommendations Wanted

Recommended Posts

I plan to drop the pan on my transmission in the next few weeks for filter change and band adjustment. Are there any upgrades that I should install while in there? No $600 valve bodies!

 

I have planned on adding the Sonnax valve to the valve body that allows flow to the converter while in Park. 

 

Stock truck.

The Sonnax manual valve by itself won't get you too far. Your results will be disappointing. The Sonnax valve works well (I use a ton of them), but not with the stock pressure regulator setup. It will change very little from what you have now.

 

If you're looking for other mods while you're in there, I'd replace the plastic accumulator piston with a Sonnax billet aluminum, and replace at least the intermediate servo cover with a Sonnax billet...or, better yet, replace them both with TCS units. I would also replace the pan itself with a deep aluminum unit.

Borgwarner solenoid.

 

Why not do a complete valve body workover since your going to take it apart

 

If your granny is in good shape it might be time to pump the pressure up.

@DynamicI purchased the following, please let me know what I'm missing!  Keep in mind my truck is essentially stock, and in 6 months I've driven 14,000 miles, maybe 80 miles with a trailer hauling a small tractor (Kubota B2150).

You're definitely going to want to replace the governor pressure transducer as well. I recommend the Rostra HP.

 

I don't see anything that is going to raise your line pressure up to where things need to be, and firm up your shifts. That is arguably the most important thing you could do to your transmission.

 

Like I said before, don't expect great things from that manual valve with a stock PR setup. It's a fine piece, but by itself will have limited effectiveness.

Could he drill the lock up, aswell as 1-2 ports in the plate. And run stiffer springs. 

 

I know your not big on shift kits but would you recommend one to raise pressure and firm shifts up. Maybe shoot for 120 or so locked.

ATSG 47/48 manual should be on your list.

I have a PDF copy of the ATSG manual. I could upload it to the site if someone verifies that there is no major copywrite issues. The FSM is on the site already, so it's probably the same thing.

Are there time limits on copyright?

 

I alwasy find some folks miss use the whole copyright thing and try to just say its copywright protected when alot of times its not.

 

Doubt that in this case. Guess Im already in violation by posting this from the book.20190510_130133.jpg.f0b5f250577be79e4039698e1610f4a5.jpg

Fair Use Law

The doctrine of fair use developed over the years as courts tried to balance the rights of copyright owners with society's interest in allowing copying in certain, limited circumstances. This doctrine has at its core a fundamental belief that not all copying should be banned, particularly in socially important endeavors such as criticism, news reporting, teaching, and research.

Although the doctrine of fair use was originally created by the judiciary, it is now set forth in the Copyright Act. Under the Act, four factors are to be considered in order to determine whether a specific action is to be considered a "fair use." These factors are as follows:

the purpose and character of the use, including whether such use is of commercial nature or is for nonprofit educational purposes;
the nature of the copyrighted work;
the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
the effect of the use upon the potential market for or value of the copyrighted work.

So... What I'm getting from that, is I should upload it. Lol.

 

:whistle:

 

That is why the Downloads are member thing. That way they are not displayed to Google or the public but the membership pool here can glean the information needed to repair their trucks. I see it as an educational purpose.

Done. Pending approval. I used this manual to rebuild my trans recently. It was very helpful. I'll be installing the trans this weekend hopefully. I also took a pile of pictures, so I might do a redneck homebuilt trans writeup, for a fairly basic rebuild.

If you're asking me, yes, I'm a big fan of higher line pressures and firmer shifts, but not at all a fan of using "shift kits" to do it.

10/4

 

Thought maybe you would think better of one shift kit over another.

 

I dont think I'd do the work that's being done in this thread without doing a shift kit.

Something the normal guy can do

@Dynamic built my 46RE for my 1996 Dodge Ram 1500. No shift kit used but custom drilled and modified the valve body and the entire transmission. As for just bolt on fixes for 47RE I don't suggest it either being valve body is only part of the puzzle and entire transmission needs upgrades to hold up to the abuse of more power.

I agree. Dynamic uses his plate his mods, sorsed springs who knows what all else. It's a dynamic tuned valve body hes putting together what hes found to work over years of experience. 

 

A regular garage guy can tune a valve body and buying a shift helps him do it. I've only dealt with transgo. And dont have anything bad to say. However I'm always wanting to learn more. There are mods I didnt do mods explained in other kits. Mods for stock trannys to ones built similar to mine. My build is just a basic build around a daily driven truck that tows. Extra clutches bands that arent kevlar most the billett stuff stock ratio lever. Upgraded this and that that I cant remember.

 

The valve body is the heart all blood runs from it spreads throughout the veins

 

I feel just upping pressure and forming shifts even on a stock tranny is a huge upgrade. 

The stuff in dynamics head is worth its weight in gold. I have years in learning the 47re and feel I've barely scratched the surface. And still feel that I have no clue.

Technically the oil pump is the heart. And the valve body is like... the arteries and valves. :lmao2:

 

Haha sorry @Evan I couldn't resist.
