TCI SSF 3500 slipping bad & chattering Well,
this is the situstion:
WOT from a dig, fine untill 1-2 shift and then RRRRRRRRR, rpms will not climb and car loosing power.
From a roll, 60 mmph or so, WOT, tranny down shifts to 2nd, carries till 3rd, shifts fine, then same thing RRRRRRR, rpms will not climb and loss of power.
If I let my foot off then punch it again it is fine.
Basically TC is slipping bad, and is chattering on lockup (something it always did).
I want to go with a Yank, what would you recommend, SS4000 perhaps? or YPT 3800 ??
Thanks

No, impossible, have a brand new FLP stage 4 (1 month old).
It used to do it with the stock tranny, but only from a dig after the 1>2 shift.
I deleted TM when I put in the FLP and its is now more pronounced and it now does it from a roll after 2>3 shift.
I know the symptoms of TC slippage, and mine are tipical, I've experienced them before on some other applications. There is no doubt in my mind. It is the TC. My racing colleagues feel the same.

Lockup chatter probably has to do with the ATF in
there. I had bad results from B&M Trick Shift like
that. I only use Castrol DexIII now.
Misfires will also make for lock/unlock, should be
slower than "chatter". This may want programming
to raise the misfire detect threshold. Lightweight
converters aggravate misfire detection.
I have had problems as you describe, with the
motor "hanging" at shift events. I believe this was
related to TM as timing was pulled and then RPM
drops back just enough to no longer satisfy the
shift criteria. At least, this is my conception of what
was going on. You might recheck the TM settings
and also disable tranny "abuse mode" and zero
the spark retard values for it, just on the chance
that it is activating.

I was contemplating swapping to a Yank converter, would a tighter converter solve this issue??? Something with a 2.0 str maybe? Like a SY3500 (1.6str)? or a SY4000 with 2.0 str?

I have a tci 3500 ssf and a large trans cooler. I had missfires on converter lockup. It also made noise too. It would not shift at wot hitting the rev limiter. I read alot of posts and the fix was simple. I over filled the trans with fluid. Wot shift pressure affected if you do not have enough fluid. Adding my oil cooler lowered my fluid level by 1 quart. Now my trans works great. My tuneing was done by tsp and was mail order. I used gm trans fluid.

Also i live overseas so exchanging the TC would cost me as much as a new one in shipping charges alone.
But I'll PM him anyways to see his thoughts on the subject. I read he is really "stand up" on helping with issues.

That shipping has to be a killer for you. Not to mention the extra wait. We in the states dont realize how lucky we are to have so much available so close. I dont imagine there are any sponsor shops within 10,000 miles of you LOL. Can you get a custom program emailed to you for the VHP tuner. RWTD has been very good about emailing me custom tunes for my predator. Good luck

Predator Z,
Anytime that you have a converter that chatters upon lockup clutch apply, it's important to fix it immediately. It could be that the lockup clutch has failed from repeated slipping. If this has happened, the best solution will be to replace the converter and clean out your transmission pan and install a new filter.

Yes, quick reply, but i PM'd him also.
The thing is I really liked what the TCI was achieving, however it was only a year old. It shouldn't have shattered in the first place or slipped for that matter.
Now my faith in TCI product has dropped and I'll be a stupid *** if I bought another SSF 3500 to replace it.
Will I have better luck with YANK, I shall see.
Also as you all know the TCI only has 90 days warranty, so that one is a write off. I can't detect any hint of even, "send it back to me and we will take a look at it, fix it or replace it", as far as replacing it, I figured that one out allready.
Now these are my mods, Stealth II cam only, Full bolt ons, dry N20, 3:73 rear. From the Yank list above, what would you guys recommend??

Predator-Z,
I'll be glad to swap it out for you since it's been chattering since you bought it. I do want to get your old converter so I can see what happened to it. What kind of fluid do you use?

THE SSF 3500 is my actual converter that I'm having the problems with, give me one reason why I should buy another one.
I've also been looking at VIG 3200, similar to the TCI 3500 and on sale at T-Byrne $650. 2 years warranty and one free restall.

I've always used Dextron III from GM. My new tranny is an FLP vacuum modulated stage 4 and only accepts that.
