New Trans

Denver · Jun 8, 2016

Go with the John Wood transmission. 140k miles on mine and performs great. All of the parts are built to his specs and are only found in his transmissions.

Well, I think I might be close to making a decision soon. As much as I wanna stay local because of convenience, I just don't know of anyone with experience with them and am leaning heavily towards John Wood. Before I do, would you guys recommend changing out the flexplate while in there? It's the original with over 290,000 miles on it. And if so, should the bolts be changed out as well along with it?

greyford1979 · Jul 19, 2016

Well, I've started buying stuff to get ready for when I get my trans. Already have a new 6.0 cooler, a new flexplate just in case and have a chit ton of Schaeffer's trans fluid on the way.

Im having a stg2 sam wyse built. Rated for 600hp and its damn near a full roller trans.

pardon my ignorance...what is "full roller"?

Arisley · Jul 27, 2016

No bushings, all bearings.

Yes. Billet and 300m are used because the shafts are taking a beating trying to transfer power from input to output shaft. By putting roller bearings at each end you may make obsolete bilet or 300m at all but the highest hp levels. Sam is the only one doing it as far as I know. I hoped to have my Trans already but its pulling season and hes got local customers.

I was going to get another twisted but the one I need is 5500 bucks...

Got it -thx

if i didn't have a bts and know JW, id be goign to wyse, hes gotten big lately it seems like. But i will vouch for what jomax said we do have a reallly good local builder a few hours away. It put up with david's truck even tho it wasn't really big power, but it got towed and dragged a lot and the guy is pretty cool. which is impossible to find and his prices are under $3k for a full build w a good triple disc tc.

TyCorr · Jul 28, 2016

I wouldnt wish a bts on anyone. Ive helped three people deal with problems buying one of his trannys. Some guys gave zero issues. The ones that do, have big ones. My old twisted 4r is in a guys truck that couldnt keep his bts alive. First the converter, then the pump, then he lost reverse, sent it in, clutches were fried. I sold him my twisted and 11 months went by and his bts finally got dhipped back. He put it in a stock eclb he bought to tow with and after two months the converter went out lol. So he bought a roadrunner triple disc and sold it for 3 grand. He has a twisted stg 1 in that truck now and the stg 2 i sold him is still going. He said he's put 100k on it. I put 20k. Good transmission builders.

Jw is good from what Ive heard. Ive only known one person locally who had one.

yeah took 4 months + for a repair on mine, good thing i had other trucks. I destroyed the PI tc 2x but figured out then the "time" it was built they had bad batches, been good so far and putting more power out of it and more drags haha.

Thanks a lot, I thought I had made a decision finally, and now I'm back to deciding between this and a John Wood LOL. I've had experience with the John Wood, my brother's truck, amazing trans. But will cost more and the distance, plus putting it in myself. The Sam Wyse I don't know as much but I'm hearing good things. Plus he's more local, about 2.5 hour drive and will cost less with install. I think my trans will blow up by the time I make a decision LOL. I think it may come down to who's I can get first.:fustrate:

Maybe I just don't understand transmissions, but how does roller bearings make the shaft stronger than if there were bushings?

if it is anything like a stock gtp38 vs a gtp38r ball bearing turbo, its friction. less friction less abuse... but then i dont know chit about the internals of a trans.. lol

But I do, and I can't understand how roller bearings make a shaft stronger.

he's picking apart wording technically like he always does.

Roller bearings reduce stress on a given shaft. They don't make the shaft stronger. The end result is the shaft lasts longer which is what the consumer wants.

It doesn't technically. It doesnt change the metallurgy of the shaft. But if people add stronger shafts to transmissions because they are a weakness or an inadequate part in that system perhaps they can be improved in their use by reducing forces and friction acting upon them.

Idk, though, you'd have to ask the guys who designed them why they didnt utilize the energy transferred through the shafts more effectively

Only because what I read doesn't make sense.

I don't think roller bearings reduce stress on a shaft by any amount. They do reduce torque to turn the shaft, and maybe that's what you mean. If the torque to turn is lower it doesn't mean the shaft has less stress. It means the rear axle gets the few extra lb-ft of torque. The shaft still sees the exact same amount

As shown above if the torque to turn the shaft is lower, it just means more torque at the other end of the shaft. The shaft sees the exact same stress either way.

Because it wasn't worth the cost. It adds quite a bit of cost to the transmission for a benefit that is too small to ever be measured. Maybe at extremely high torques it makes sense. I never tested a trans at those levels.

When you're building a several thousand dollar custom transmission you can afford to put roller bearings in. When you have hundreds of thousands of these built every year adding that type of cost adds millions of dollars, and there isn't enough benefit that anyone could actually measure it.
