Review: I have owned two third generation Acura TLs with 6 speed manual transmissions at this point. I bought one at 129k miles and the other at 84k miles, with the higher mileage TL being a 2005 base and the lower mileage one being a 2008 Type-S. The 2005 had issues going into third gear pretty often (i.e. every few shifts). It would feel almost like it went in, but then would pop out as soon as you released the clutch; I was not skip shifting and have never had a similar issue in any other vehicle over hundreds of thousands of miles of driving other manual transmissions, including mostly Subarus, Isuzus, and BMWs as well as motorcycle and dirtbike transmissions. The 2008 had the same issue, but only once every few dozen shifts and it could be avoided completely by preloading 3rd gear a bit and shifting really slowly. On both vehicles, I changed the transmission fluid to OEM honda fluid and drove for about 500 miles and didn't notice any improvement. I then changed both vehicles over to this stuff and they both felt better right away and felt even better after 100-200 miles. Neither has had any issue whatsoever going into third after the fluid change to this stuff. I have about 12k miles on the 2005 base with no degradation or return of the issue, but only a few hundred miles on the 2008 Type-S. I'll report back if there is any long-term harm in using this fluid on the 3G TL platform, but for now I'm enjoying the improvement in shift quality.
Review: If you own a 90s Honda this is a must. I experienced significantly better shifting immediately after I replaced the transmission oil. It gets better the more you drive it.

## Questions & Answers

**Q: Is this oem or best recommendation for aisin ay6 in 2010 v6 corvette? so could also be possibly better than factory toyota fluid**
A: I believe it was oem for gmc cars. The old name was "GM Synchromesh". Many 7th Gen Honda Accord owners prefer this over oem Honda MTF in their V6 MTs.

**Q: 2015 subaru BRZ 6mt,. i tried motul, amsoil, pentosin.  Is this compatible for my application?**
A: I'm not 100% certain if that is compatible fluid but what I do know is that it is AWESOME! Put it in my Acura CLtypeS because it would grind between 2nd and 3rd..drained out old fluid and put this in and within 1-2 miles of going through the gears it shifted smooth!

**Q: what is best transmission fluid for Merc SLK 230 manual**
A: Oem

**Q: Is this GL-4 fluid? It's getting harder and harder to find.**
A: Yes it is GL 4

2000 VW Jetta TDI GLS 02J Trans 157,000 miles (pretty sure factory fill or maybe one change during previous ownership) Excellent fluid that is actually thicker than VW's version of 75W-90. G070 (VW newest revision of MTF) has a cSt of about 6.4 with this stuff at around 9.0. Honda and Acura owners swear by this stuff with a majority of TDICLUB members agreeing on how good it is. The price on Amazon is unbeatable for me. $27/quart at the GM Dealership? No thank you. I actually ran the G070 for a little while and had nothing but issues in traffic. I live in Hawaii and the gearbox would get awfully hot when sitting in traffic. When it was getting hot I was getting shifting issues, 1st gear was almost locked out during a 3 hour stint of traffic! Once I refilled with this stuff I was blown away. The G070 was good when the trans was cold and mediocre when warmed up, but this stuff… I took a quick test drive and was shocked, it shifted like butter when cold. I didn’t think it was going to get any better as the G070 did okay when cold. Once the trans was warmed up, all issues were resolved. No more lock outs, no more grinding and no notchy shifts. I have put about 600 miles on this stuff and it is fantastic. I plan on changing every year or two as I do with all manual trans cars so we will see how it does in the long run but for now I can slam gears with no grinding at all. Not that I slam gears a lot but it is kind of a test to see how well it is working with the synchronizers. One last note, There is a guy on the TDICLUB that swears by this stuff and has over 350,000 miles worth of transmission wear on synchromesh, he had no ill effects running it and never had carrier bearing issues or excessive gear lash as some people would think due to not running a 75W-90 GL4 Gear oil. I assure you though, VW doesn’t use anything close to 75W-90 with their gear oil (thinner than the Pennzoil as well) and the transmissions still last a very long time using VW’s thin fluid. Conclusion, must buy for me. If you are on the fence about trying it, do some research and see if anyone has run it before on your particular make and model. What works for me may not work for you or your vehicle. Good luck!
