Well even though i promised i wouldnt do anything to this car (05 TL 6spd) i got some modifications done to make the car more fun to drive. I had the Excelerate ETD installed and the tranny fluid drained and filled with the GM fluid recommended by almost everyone on this site. Intial impressions made me satisfied with the small amount of money i spent. I am not sure if it is the fluid or ETD, or combination but the car shifts much smoother now. I find it a pleasure to row through the gears instead of a hassle. The car nose used to drop whenever i got on it hard then put in the clutch to shift. Now it stays level. I would definilty recommend both of these mods especailly for the money. The etd results in a little vibration from the engine but well worth it for the improved fun factor.
