Just curious on who has switched and who hasn't, if so, were there improvements in shifting feel?

 

again i noticed a difference where as the tranny just slides into gear. only about ten miles since i've switched but wow.. no more notchy feeling (btw i used the Penzoil stuff)

 

I have about 4,000 miles on my fluid change and it's still fantastic. It's the best thing that I have done for my car so far, followed closely by the clutch TSB.

First track day today with GM Syncromesh fluid...

Definitely holds up better when the transmission gets extremely hot. Didn't notice much difference during normal shifitng.

 

Had mine in for about a week, tranny feels about the same. The fluid that did come out was a nice clear amber color, it may have been in good condition as is. It's been about 15 thousand miles since my fluid was changed (with the TSB).

 

It might feel better on the drive to the grocery store (stk felt good enough) but it didn't work for sh!t on the track (4th gear upshift grind like a mother)

 

I just changed it today - much easier, 3rd, 4th, 5th and 6th shifting. Second has improved as well - by a lot - but it's still notchy due to the TSB not having been done yet...
