Get what you pay for, though pricey, irrefutable 'performance' gains: vehicle shifts much much much more smoothly now - no more 'crunchy' shifts, & all gears operate better in a wider range of temps as well. Prior to the fluid change, 1st & Reverse were the more difficult gears to get in to, especially in colder weather - before the fluid had a chance to warm up - now they all shift smooth as butter. I can also shift much faster as a result. Last little + is that the fluid doesn't smell horrid.

I've been using this oil for a while now and it consistently performs well. My engine runs smoothly and quietly, and I’ve noticed improved fuel efficiency compared to some other brands I’ve tried. It's a trusted formula, and you can’t beat the value for the price.
