I originally went with Redline D6 because thats what the latest update on their website stated. Transmission shifted much smoother and less notchy than stock fluid.

I have a SSK and I noticed my shifter would shake in 3rd gear ONLY when the car got warm. If the car was cold the shifter wouldnt shake in 3rd gear. This wasn't your typical shake, it was violent and Im sure overtime it might have popped out of gear.

I read that the Redline D4 is thicker oil, this past weekend I drained the D6 fluid and replaced it with D4. Now my shifter has much much less shake in 3rd gear. Gears are smooth as D6, only difference is once oil has warmed up.

I believe anyone in warmer climates should get the thicker D4 oil.
