Bands can be re-lined. Mine was welded and lined with kevlar.

I see no way possible to get 8 clutches into the forward(input shaft drum) Also it would be a waste, 4 clutches hold just fine.
I've been working on making a new forward drum for these trans that will allow you to use 904 high gear clutches. The big advantages of this would be a lot more friction material and the availability of the parts since alto and reybest make parts all day for that transmission. It's been a slow project though lol.
I haven't disassembled my trans so I don't know what the frictions look like after 13 years of service, but they have never slipped and I don't get a 2-3 shift flare, So the stock Mopar frictions proved themselves to me. I just thought maybe I could do better.
I did not weld my band because I thought it would wreck the bond of the friction; How do you weld them without messing up the friction bonding??
And, who relines bands with Kevlar? got a link?

We still tear high gear clutches every now and then its been forever since I tore a band up. We are pushing 1100-1200hp through it though, I never weld the bands and I un 180-200psi line pressure.
Alabama bands relines bands in what ever you like.
It was one of the drums he fit 8 alto clutches. Can't remember what one. His name was Racetstev on neons.org. I think he got out of neons though.

I just looked at my PM's on neons.org from Racetstev from 6 years ago. Apparently it was welded, and then re-lined with "carbon". Not sure what to make of that.
Carbon fiber. It bites REALLY hard and doesn't really overheat. Clutches, brakes, synchronizers, transmission bands...things that need a hard/fast bite where heat is an issue. It's not exactly cheap, but it does work very well.
Brian sloe had aluminum drums made for the direct drum not forward drum. I think you could fit 8 thins in it, I have one but use thicker frictions. Since the alto aren't available I switched to the stage 1 reybest.
Ive be been using the red lines bands lately, the carbon seemed to work well to. I do not like the Kevlar bands.
Thought i'd post an interesting link on the valve body.. http://mechdb.com/index.php/Chrysler..._modifications
And this on how to prep the trans http://www.turbovan.net/Trans.html
My plan is to use a 01 neon trans with the alto red rebuild plus band, nan torq converter @ 3200 rpm.. with an obx diff (need to find a spacer) -- based on a discussion with carl b a fmvb seems like my best choice.
Also, as far as the clutch pack count; when I built this unit I was able to fit five friction in the front drum using A404 steels and mopar frictions. was tight but worked perfect. should be interesting to see how they faired.
best 1/8 ET-6.16 sec. best 1/8 speed-119.70 Best 1/4 MPH 145.5, Best 1/4 ET 9.65 sec. 8 valve NO NITROUS!!
The stage 1's are a red color, I have not found any of the blue ones for a long time. I fit 6 frictions using thick disc and thin steels or 7 alto's.
Here's a pic of our new valve body we've been working on for a long time. It features reverse pattern, low band apply, clean neutral PR123N, and reverse pressure matches forward pressure so no more worrying about blowing the seal. Also this is all done using the newer style valve body cores, no more hard to find cores and the fluid flow is better.
You guys are putting that kind of power through parts you said you can't share since you are in competitive racing. Sortof a reason for people to look at 41te's since either way you need unavailable parts.
I for one, can't compete in any sort of racing class you are in.
Are you using lockup now?

Has anyone contacted Alto to see if they will re-line frictions? I know what the process is for the most part and because of what I know I wouldn't think it would be all that big a deal.
