Re: Torque Converter Chattering/Shuddering Fixed!
Thats the thing, I wasn't wanting to make a difference in the way the tranny behaves. I was hoping the additive would be just enough to affect the lockup clutches in the torque conv. enough to make it lock and unlock right instead of chattering, and not mess with anything else. I have been paying a lot of attention to the tranny, expecially after I added the stuff, to make sure that if the tranny started acting different I could flush it and go another way. So far, I have noticed no difference in the way the transmission shifts or any slippage.
Here is another theory. As far as I know, the torque converter is a fairly simple device. Basically a ball of fluid with vanes and lockup clutches. The transmission fluid creates the ideal friction properties on the torque converter clutches which makes the clutches lock up correctly when they need to, without chattering. I am thinking that somehow maybe the fluid doesn't have the ideal friction properties (for whatever reason or the other) and the friction modifier in a small dose changes the properties of the fluid just enough to make it work correctly.
Believe me, I dont just want to pour things in my transmission without thinking about it first. I thought about this for weeks before I finally decided to try it. If we determine that it will negatively affect the transmission then I will flush the transmission myself right away to remove the additive. Like I said, I am watching the transmission closely so that I can notice any changes in behavior.
