Unless they have the capability to do a catscan on the plates before they are installed, shiznick like that happens when you are going for performance.

Like I've said before, torque converter are very simple mechanical devices.

 

Can you describe, in a nutshell, what it SOUNDS like? I am curious as to whether or not maybe that is what caused my tranny issue and improper gear ratio code last week....

 

It sounds like a loose fan blade rattling, especially at idle with no pressure on it. No noise under throttle until it is about to let loose.

I ordered parts today from ZZPerformance. Talked to Tim. He said that the next thing to go will be the transmission input shaft unless I change the torque convertor to a lighter unit, ie, theirs. I trust them, so I bought a new 2500rpm stall torque convertor along with the Meziere flex plate. Total including shopping, just undet $870.
ZZP is saying, unless I'm misunderstanding, that this convertor will shave 1/2 second of my 1/4 mile time, with only this mod. They are EIGHT pounds lighter than stock!

Cost of labor in this project to be between $520 and $600 depending on who I have do the install. So there goes my intercooler money, but maybe this is for the best, if it saves my transmission, at least for a while.

 

You're right. They help, considerably. But don't you have to drop the tranny to install the converter? Please let me know how that goes Wayne! =) I'm excited for you! Glad you turned lemons into lemonade.

 

HOLY ****!!! That is awesome!!!! Definately worth it for a full 1/2 second.

 

Yes to dropping the tranny, but the motor stays in. Been there, done that once before. That's why the $575 to install. I'm also doing another tranny service, changing the filter and switching to Dextron IV, per ZZPerformance.
If this is true about the 1/2 second, yes, I DID just turn lemons into lemonade. I don't feel quite so bad about spending the $1,500 if it helps the performance THAT much.
Going to do a full service, too: rotate tires and oil change. Thursday, it looks like.
Still looking at installing the intercooler, roller rockers, pipes, and dyno tuning this spring. Then it will be time for a RACE trans', because this one will probably go BOOM!
