Here's one more for now ... until I attempt to install my new H&R rear sway bar anyway
I have not tried this one, though I intend to before this winter to see if this will help the notchiness I feel in the stick (no smart comments
) when it's cold outside.Just like the CDV change, I had this saved from a previous "Z forum", so I cannot take credit for writing this.
Good luck!

TOOLS/PARTS required
-jacks(two would be nicer) need LOW clearance jack or buy cult wood from home depot to get your car high enough to clear the jack.(front wheels)
-Jack stands...DO NOT PROCEED WITHOUT ALL FOUR
-2 quarts of Redline D4 ATF (2.5i takes 1.1 quarts , 3.0 takes 1.3 quarts)
-fluid pump
-17mm WRENCH & Socket
-Brake parts cleaner(clean off excess and clean out the pump if you are doing other projects)
**DRIVE AROUND THE BLOCK, WARM UP THE FLUID BEFORE PROCEEDING**
first you need to put your car in the air. ALL 4 wheels and needs to be leveled. I jacked the front end first, each side separately. once one side was in the air, i put the jack stand on the front control arm since i could not find a suitable place to put the stand. for the rear, i jacked it up from the differential where the two bars come together(you can identify them by the two silver screws that are visible from the rear) then once it was lifted, I put two jack stands underneath the proper jacking location. **please pay great attention when jacking up the car and putting it on the stands. CAR MAY FALL if not done correctly.**
UNSCREW the FILL PLUG FIRST ALWAYS!
fill plug is already removed in the picture. FILL plug is easier to get with a wrench but you can squeeze a socket in there(i did)
once you have removed the fill plug, remove the drain plug. it will splash out.
after you let it sit for few minutes, put the drain plug back in. and proceed to pump the fluid in. It shoudl be RED in color as with other Automatic Transmission Fluid(yes i've researched, Redline D4 ATF is the fluid to be using) continue to fill/pump until fluid comes out of the fill hole.
once thats done, put the fill plug back in and thats it!
