jcb Senior Member First Name Jeff Joined Jun 15, 2025 Threads 12 Messages 112 Reaction score 138 Location USA Vehicle(s) FL5 Type R CW Oct 25, 2026 #17 I've gotten to 6500 miles and the 1 to 2 shift is not as nice as the others...not a grind, but not buttery nice....so I plan to change the fluid. For those with issue, the AC Delco seems like the best opion based on skimming a lot of posts (so not scientific at all. )

I still manage to grind 1st to 2nd when accelerating hard and shifting fast. Sometimes it wont even go into 2nd and I have to slow down and try again. But as someone mentioned above, probably a driver error... BTW, I had the same experience with my 07 FA5 Si Sponsored
