Review: I wish I'd had this years ago. - I've owned my 02 Acura RSX Type S since new in August 2001. It is still the best and most fun car I've ever owned in my 50 years of driving. The only complaint I've ever had was shifting from 1st to 2nd gear. The speed of the car, whether sedate or aggressive didn't seem to matter. The ratio jump between 1st and 2nd gears is substantial and it was always clunky, sometimes grinding. Down shifting was never an issue from 3rd to 2nd. In the last few years I've tried several things to improve the shifting. I started with a short throw shift lever from B&M which seemed to help, but in reality caused the shift cable end to bend, because of the design of the lever. What had helped was the removal of the rubber bushings that mounted the shifter housing to the floor of the car, the B&M kit included aluminum bushings to replace the originals. Mounting the housing solid took out unnecessary movement and wasted motion. This past February I swapped out the entire shifter mechanism for a billet aluminum unit that definitely improved things along with new shifter cables from the same source, K-tuned. This past Tuesday, I drained the Honda manual transmission fluid for the Red Line MTL. Almost immediately the shifting is smoother with no clunky 1--2 shifts. The car has 92,000+ miles on it. The trans oil has been replaced according to the manufacturer's outline, so this last change was 30,000 miles early. I really wish I'd known about Red Line MTL ten years ago. This stuff really works. Update: August 31. Since replacing the Honda manual transmission fluid with the Red Line MTL, I've been to Michigan and back and Wisconsin and back to St. Louis. I did normal maintenance on my car last weekend. Checked the transmission fluid and it was as clean as the day I installed it and shifting is smooth, almost effortless.
Review: Great fluid - This came highly recommended as a replacement for the OE MTF in my FL5 Civic Type R. After driving around for a few weeks I can say the shift quality improved - especially shifting to/from 2nd. Cold-start shifting is also improved somewhat. Overall I am satisfied. The FL5 CTR takes a little over 2.3 qts.
