I got my car back today and WOW what a difference! I never had really bad problems with my MT-82, but XL-18 really made it a lot smoother. I only drove it less than 10 miles, but it was already clear improvement. I think that it will get even better when I get more miles on it. Might be placebo, but I would even say that my transmission is now little bit quieter than before
I paid ~$30 for XL-18 and my dealer charged $25 to install it. One of the best investments so far. I am really happy and I can recommend this to everyone who does not already have XL-18 installed.
