No trace of packaging

A glass of oil being thrown into the box rattles. It dripped a little, the bottom of the jug was dented. Is there too much spacer paper?

Pros
  • Everything is fine!
Cons
  • No power

Wonder oil! for oils and fluids

Makes a world of difference to my 2006 Chevy Colorado 5 speed truck. Shifts super smooth now. I used to have trouble finding reverse, but not anymore. WOW i love this!

Pros
  • Pretty impressive
Cons
  • Mostly good but...

2008 Civic SI - Transmission Fluids

Great Product! I recently changed the fluid in my 2008 Civic SI because I felt like I was walking through a box full of rocks. This product immediately improved the overall feel and made shifting easier on cold starts. 5/5!

Pros
  • Confident
Cons
  • Volume

Perfect for Acura manuals

This is the best manual transmission fluid for my 2005 Acura TL. Not that you've ever heard of Honda/Acura, but those boxes tend to refuse to shift into 3rd gear. This is a known issue (similar to Honda transmission errors mentioned in other reviews here); Also check the Acura owners forums. It has been 100% smooth shifting into every gear since I first started using this GM SFM about 75,000 miles ago. The car has driven almost 120,000 km and drives with confidence.

Pros
  • Sturdy construction
Cons
  • Crumpled

Works in a 2006 Honda Accord

There was an issue with the 3rd gear synchro where the gears would occasionally grind after the clutch was released. My 2006 6 speed Accord coupe V6 originally used Honda manual transmission fluid but after installing the synchromesh I have had no synchro and transmission problems for over 150,000 miles! Even after 100,000 miles, the fluid remains golden in color and will hold up after thousands of freeway miles. This material may be expensive, but it's worth it as it lasts longer than theโ€ฆ

Pros
  • Easy Tuning
Cons
  • Clarity

Phenomenal for a Honda transmission

I drive a 2004 Honda Accord V6 6MT coupe and recently changed my manual transmission fluid to Honda Genuine. I was disappointed that the notches and the overall frustrating shifting experience didn't go away or even lessened. I've been reading the forums and found that this Synchromesh stuff seems to be magical in its effects, so I gave it a try. It really really works, the jaggedness went away immediately. I will post any updates as needed. The packaging was good too, but one bottle leaked aโ€ฆ

Pros
  • New
Cons
  • Not the best

Used this to change the manual transmission oil in my 2003 Honda Accord LX 2.4L. Ever since I bought my used car (130,000), I assumed the transmission would never really be amazing. Until I filled up with oil. The heaviness when shifting into first and reverse gears is gone, and the harshness when shifting from 1st to 2nd gear is significantly reduced so that it no longer bothers me. I would recommend this gear oil to a friend any day and tell my mom and my girlfriend (both cranks) about it toโ€ฆ

Pros
  • Nice to use
Cons
  • Cord is shorter than other parts

must have been designed by NASA. fantastic results!

Just changed MTF on my 2013 Accord EX with 44,000 miles. I had sporadic nicks in 2nd, 3rd and 4th gear, and sometimes at traffic lights it wouldn't go back into 1st after coming to a full stop. None of these issues were serious, but annoying nonetheless. After reading the reviews here and watching EricTheCarGuy's YouTube video, I decided to try this GM fluid in the Accord. Fantastic results. Notches on 2, 3 and 4 have almost completely disappeared. Maybe there is a little bit in 1 in 10 shiftsโ€ฆ

Pros
  • Everything is fine!
Cons
  • Band

So good, literally, that it eliminates minor mechanical issues.

Oh my god. This stuff is from another planet. I feel like if I had a broken trance I could pour this stuff in and it would magically fix it. But seriously, it helped a BIG time to fix a typical 2nd gear synchro problem in my '99 Honda Civic. A forum I visited once referred to shifting as "moving a wooden bar over a barrel of coconuts," and before I replaced my gear oil with a modified GM friction mesh, I thought the same thing. Instead of a rod in a barrel of coconuts, I now have a hot knifeโ€ฆ
