With the tempuratures begining to climb due to summer weather, the chances of warping a rotor is pron to happen. Only way to tell is to have'm turned. It will cost about $10 per rotor plus installation unless you do it yourself.

Hopefully, it's not your tranny that is doing to shaking

I think I have the torque converter shutter, because everytime I give my car gas when it drops into overdrive, it shakes a little. Someone on the board told me to add "friction Modifiers" But I didn't because I don't wanna screw up the trans. anymore than it is. Will the modifiers actually help??? and how much would I add?

thanks

How many miles are on your car? If you've got a lot of miles it's probably best just to leave it alone until it dies in most cases, unfortunately. However, if you don't have really high miles, you'd probably be better off to get a full tranny service - get the fluid flushed and get the filter and everything changed. It's sort of your call if you want to risk messing with it. Sometimes the things get to the point where there's stuff in the fluid and that's all that's keeping the friction for the tranny to work (I'm not good at explaining that). But it doesn't sound like yours is that bad... not yet anyways. :)

back on topic... yeah, I think my rotors may have a little warpage - not much, but a litte...

Does the shaking occur in every gear at 3k RPM's? or just certain gears? That could be relevant in determining if it's the tranny.

Also, I've had my tires balanced at places before whose machines were screwed up and actually messed up my balance. I wound up going to the stealership whose machine was right and they would actually guarantee their work - they were able to get it right... so you might want to check on that. The only way I can think of to test that is to switch your front and back tires (in a normal rotation pattern) and see if it still does it. If not, then it probably is just the tires... if it still does it there's a chance the tires are screwed up on both front and back or it might not be tire balance.

Hope this helps... :)
