Can anyone point to proof of this fabled "less than mtx drivetrain loss" figure?

I've asked before yet no one has been able to produce any evidence. It seems to me alot of people are taking this as fact and I just want to know where's it's coming from.

From what I know, only one person here has had level-10 work done but has not put the effort to dyno before and after.

Sure, it could be stronger, firms up the shift points, and with a higher stall which would be quicker out of the hole but that doesn't mean it's going to be more effecient at putting power down than a manual transaxle.

If I were plucking down over 3 large for this, I sure as heck would want some type of proof because I think you could do alot better with an upgraded swap.

well it seems no one here quite sure. only reason that it might be a fact, is because the atx's are electronically controled. and with programing, and new internals, they can be made to shift at the right time to get the best out of it.

but a human can not be programed to shift at exactly the right time, every single time he/she shifts.

nitros, i think u got it right. can someone tell me why it shouldn't be more efficent? u figure better parts that have reduced power loss, why should a MTX always have less loss? ask level ten for some proof if u want it, i'm sure they could point you in the right direction.

Shifting at the "right time" has nothing to do with drivetrain loss.

So you are not quite sure?

Ok i just emailed level ten requesting the information we all seek. Hopefully I will get a reply.

i'm also thinking about getting one of these rebuilt cd4e's i'll have to hold off my plans for nitrous, headers, and other goodies but if its going to help that much i'll be perfectly happy i'm sure.

nope, i'm not master tranny expert, i just now some basics.

I have a 98 se with the duratech and very badly would like to put a MTX in it. I have a chance at getting a MTX w/46K out of a 99 csvt that was totaled for around $350. Where could i get it put in if I can get it put in at all??

I have looked on the level 10 website, and although they probably are a good idea for anyone having tranny problems or doing a lot of mods, there kits don't actually say anything about reducing drivetrain loss. Now I know they build ATX's that have a very low loss, (supposedly much less than a STOCK MTX), but I also know these will be much out of my price range. They also sell a kit that you can shift an ATX like a MTX, but again, extremely expensive. (a little over $1,000.00) And for that you are giving up an ATX's only advantage (exact shifting).
I think I will do as Roadrunner suggested, and get a used contour with a MTX, and just make the switch. Has anybody done this, anything I should watch out for? How long should i expect this to take?
Thank you all, and by the way, This is a great site, and I am very impressed that you all have managed to put together such a great community.

Here's an interesting story.
