| aluminum valve bodies | Login/Join |
| DRR Elite |
BTE is clearly CNCing their aluminum valve bodies in house in the USA and don’t have issues with theirs unlike FTI which has been stated here by a few. Bottom line is soon every race trans builder will build their trans with and only offer aluminum valve bodies. | |||

An ALUMINUM transbrake body with a STEEL Valve and no steel sleeve in the body it is very likely to gall the aluminum body. Does any of them have a STEEL sleeve? That is the one I would look at. Otherwise just not worth my time, money or chance to try it. Steel tends to tear up and gall aluminum. Aluminum expands more and faster than steel when it gets hot. Both of those are not good things here. Saving some weight is a good thing if it does not create other issues. Sure it MIGHT work well. The question is how long will it last and will it fail when you need it most? https://postimg.cc/gallery/np3zpruo/ "Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability.

If not there is no point to argue. 4X NE2 CHAMPION. 2020 TDRA NE2 Champion | |||

The aftermarket, those companies that build race transmissions, converters, valve bodies and components disagrees with you, a nobody who does not build no mind manufacture race transmissions, and their components, what a surprise.  | |||

I believe it was end of 2013 bracket race season at Our track awards dinner, Wendell Dunaway whos is a local race trans builder and BTE dealer had a display and had the BTE billet valve body. Pretty sure BTE was the very first to build one, a year or so later FTI came out with their version which may or may not have been a reverse engineered copy. I tried one and during the 2nd season and 100s of runs it became VERY inconsistent and I went back to a cast iron VB. But this was 5 years ago, improvements could have been made since then. Like I said earlier unless you want to save 9lbs I personally see no benefit in a bracket car with a delay box. In a .90 car on the .370 tree I can see a benefit "IF" they are indeed quicker. I also agree with Ed, at some point all builders will be selling then because the cast iron VB cores will dry up at some time in the future, but even that is several years out IMOThis message has been edited.

Although I do like the steel or cast sleeve idea your concern about thermal expansion is not valid here, the delta between steel vs AL for this case is about .0005" max. There are many AL VB out there and have for a long long time now that work very good so your statement about galling is also not valid. No one is forcing you to run one. Nothing is perfect, if it's manufactured wrong you will have issues no matter if it's AL or steel/cast. | |||

I don't know who manufactured the first AL VB but it was not BTE! Hipster has had one out there for many years now... | |||

Hipster ain't billet aluminum. JW has the fastest Pro Tree transmission brake VB printed on a time slip, on the planet. Double 0's on a 370 pro tree staged shallow 3200 lbs 10 x 28 bias tire. | |||

The debate between Top38 and BigSteve, is who made the first billet aluminum. I don't know who did, but the original Hipster was cast aluminum. If I were ProTree racing, I'd run a cast metal OE JW. They're the fastest Powerglide VB's on the planet, evidenced on a time slip (in reality). | |||

For the purposes of the arguments on hand, Griner had the first billet one. Hipster and TCI both had cast versions for years (Hipster/ATD is now billet), but I think we had the second billet version. We've sold thousands since. Ours is not a radical redesign like several on the market - we just went with what worked - conventional regulator, manual valve etc. As far as putting sleeves in these goes...its not an easy install. The regulator could potentially be sleeved, but I have been suggested by some people that I respect very much that a coated aluminum valve would be the best option - we are looking at this now. That said, these transmissions don't see anywhere close to the cycle time that a daily driver would see, and as such, I don't see major issues with these for racing usage as they are. | |||

Thanks for setting the record straight Brandon. | |||

Just for the record, I never stated anything about BILLET! Just an AL valve body... You ASSumed Billet! You may now continue with your babble. | |||

You're the one arguing who made the first billet aluminum, I could care les. I've got twenty cast untouched valve bodies, two cast Coan bracket VB's and one fast JW Pro Tree VB, and JW ain't far from me, I'm sure they'll do em up if need be, or TSI will, if need be. There's no billet VB needed here. Argue on, I could care less who has or did what. JW has the fastest Pro Tree VB on the planet, it's cast metal. | |||

I like the idea of aluminum valve coated. What about a composite valve like what sonnax is selling in their zip kits they make for the newer transmissions? Jeremiah Hall | |||

That's just it shyt stain, you made my point for me. Big Steve said he thought that BTE were the first to make a *billet* VB, you then claimed Hipster has for many years. Keep dancing for us you stupid mother*****er. | |||

Why has nobody said anything about the ATI aluminum valve body? Just wondering. Bob J Don't get behind me,I'm in the slow lane. | |||
|

I didnt know me and Top38 were having a debate, I stated I thought BTE was the first billet VB when I saw one back in 2013. I was clearly wrong and he corrected me, no biggie to me | |||

ATI’s strong hold is stock/super stock, not bracket racing and not dragsters | |||
