just wanted to share this, i had changed my 3650 manual tranny with some autozone synthetic fuild (castrol?) about 400 miles ago, i have had a little bit harder time shifting and taking longer before it gets warm to shift right and i bit nochier, i just decided to see if redline d4 would make a difference, and yes it did, shifts better from the start, less whine out of it, and feels alot better.... also i think i might have put 4 quarts in b4, and now i added 3.4 quarts or so into it which i heard helps also..... so spend the extra money its worth it
