I have have the ST 3700 and I'm pretty sure I have had the shudders for a while now. It mainly happens on the highway when I give it about 1/2 gas or so. It kind of shakes and doesn't want to accelerate. Anyways, I was mainly wandering if this is going to cause my trans. to go out or if it will eventually destroy the TC. I can live with it for a while b/c it still goes WOT ok and runs fine until I get some more dough to fix or replace.
Thanks

Do you have programming?

Those are legitiment concerns. That lockup clutch is slowly destroying itself. Smell your tranny fluid. Smells burnt doesn't it?

I've got the same problem and am still undecided
as to a replacement. By the time I replace it with my stock converter, send it to Yank for a new clutch and put it back in, I'm looking at 9 bills with little faith that it won't happen again.
Was considering a TCI but their warranty sucks
and Yank did a nice job destroying their credibility for me.
I'll probably go with a P.I. or Midwest, only because I've heard few complaints on quality or customer service issues; although I'm really tempted to try a Yank SS3600. But the old adage:
Fool me once, shame on you
Fool me twice, shame on me
keeps popping into my head over buying another Yank. I'd have to say that I really feel hosed by Yank over this issue. Their treatment of this issue is the biggest crock of sh*t since Godzilla
took a dump in NYC.

Yes, it can be rebuilt. I know that TCS will do it and probably others too.

Yes, it can be programmed around. Its simple to fix in the lock-up table. Have the converter unlock when you get to 50% TPS or wherever the problem occurs.

Colonel, I had the shudder issue with the prototype ST 3500 and my fluid was fine.

Timelord: Call Yank; while they are sometimes tough to get on the phone; they are generally not very consistent in replying with e-mail.

Too late,opted for a COAN 10" Lock-up /3000-3200 stall /anti- ballon /steel stator.

No programming yet.

Is this generally an unfixable problem? I would like to take it somewhere and have it looked at/fixed but if it is pointless I might as well just skip that part and keep saving for a new one. <img border="0" title="" alt="[Frown]" src="gr_sad.gif" />
Or put the stock one back in and be slow again.

Strange. I had that problem with my Yank 2400. It was in for about 4000 miles I'd guess. The fluid smelled really burnt but there was VERY little debris in the pan. I don't think it was the tranny clutch packs or there would have been more stuff in the pan. Those clutches are still going strong too.

How long was your clutch chattering?

It didn't chatter right away, so I'm guessing it was for only a few thousand miles and the chatter wasn't that bad. it only happened under limited circumstances.

That prototype had the original YTP kevlar clutch before he went to a kevlar with a modified surface to try to eliminate the chatter. He said after he cut it open that the clutch was fine, but the surface didn't allow the oil film to spread right or something to that effect. so then he tried the modified clutch surface in the YTP series. The ST production series didn't use kevlar because of the cost; I think it was Carbon Ceramic but I've forgotten.
