the same conclution. It seems that my clutches are chattering upon lock up. If I place my shifter in 3rd and as it locks up I can really make them chatter when appling a little throttle. It almost sound like my metal pipes clanking together. When we took it on the highway the tech touched the brake to un lock the converter and then applied some throttle and made them chatter not as much as in third but still there.
Next step is to pull the pan to see if any crap is in there and 3rd Call TCI.
Damn...... I hope TCI will work with me.
How are they to deal with? do they send out new units ( so no down time on the car and save labour ) and wait till they get the old one back, What your experiance?

You may want to raise the line pressure during TCC
apply at low line, and eliminate the PWM function
(either raise the min value or do it in the hardware).
See what kind of options you have for this kind of
tune editing. TCI lockup clutches aren't the greatest
but you might be able to get by. Also use the best
quality, anti-chatter ATF you can find.

Thanks for your input jimmy, you have helped in the past. I was thinking the samething about anti chatter additive and/ or fluid. Do have any thoughts on brands of oil or additives?
This is one brand the fellow that installed my TCI likes
As far as the programing I have no way of doing it by my self. I would have to get that done by the guys in Toronto by http://autoworxperformance.com/.

its not hard to mechanically remove the PWM function. all you have to do is stake the PWM piston into the housing. very common thing to do so you can use a 95-97 LT1 trans in a 94(no PWM). I didn't see prices on that site, but if thats the only thing you want, or if your more budget oriented for a full tune, a custom mail order will likely cut it for less. like madz28, or pcmforless

I use the Castrol DexIII, any major brand that has
the latest automaker anti-chatter specs covered
should be OK. I wouldn't put any synthetic mystery
goo in there, without TCI blessing it; blue mystery
goo was what precipitated my clutch problems at
a couple hundred miles from new (B&M Trick Shift).
TCI clutch material is not the same as OEM and
every materials system is a crap shoot that way.
Not like the goo chef got to test the recipe on
every converter brand out there.

I talked to Will at TCI and he said to use this stuff to eliminate TC shudder.
