Query: Not impressed

Changed my manual transmission fluid with this in hopes that it would improve shifting and shifter feel. While there's been a definite improvement in shifting when warm, it performs horribly in the cold - far worse than the OEM dino fluid. For the first 5 miles it's like I'm shifting through peanut butter and gravel. Definitely going with something else next time.
