    Same stuff, less money

    This is the same as the expensive GM Synchromesh at about half the price. Perfect for use in transaxles that have brass synchros (any make).

        Initially serviced 6 spd manual transmission with another brand. Transmission shifted poorly after servicing. Changed to Pennzoil Synchromesh and the difference is incredible. Smoother, quieter, works as advertised.

            I purchased a 2004 Mach 1 Mustang. It has a five speed and I noticed that the shifting was not that smooth. I decided to change the transmission fluid and had read that the transmission manufacture recommended Synchromesh. The change made a nice difference in the way the transmission shifts, no grinding, nice and smooth.

              GL-4 is for MT and GL-5 is for diffs. "Quality" is the same, but GL-5 has friction modifiers that would disallow syncro engagement in an MT, which need to grab in order to spool up.

              Don't worry about brass and copper parts, the MT-1 spec ok's that use. Harmful activated sulphur additives are a thing of the long past.

                  I use this product in my 94 Sentra, developed a leak and I replaced half shafts, so I've probably added a complete bottle and half. The manufacture said use GL for brass/yellow parts, and this is only one I found left on market. I would suggest to anyone needing for older model cars with brass trans parts. My Sentra has 300,000 miles, and this works great, no problems at all shifting, so I would highly recommend.

                    This is recommended for the T-56 transmission on my z06 corvette. I used the fluid and the transmsissions shifts smooth again. I had over 80,000 miles on the car and the person I got the car from said they changed the fluid. Which the fluid had not been changed. Very nice to be able to get what is needed at a local store!

                    I used this oil for my 2005 Civic Si. Car had 143,000 miles before the change and shifts were notchy and sometimes difficult to get into second gear - Car has NEVER been abused or raced. After replacing the original oil, I saw a noticable improvement in 2nd gear shifts, and smoother engagements in all the other gears.

                      Old manuals need to stay away from newer fluids Gear oil because of the chemistry. They are not good for synic gears. GL5 can harm them. This fluid is made to protect them.

                          As someone else mentioned, this is supposed to be the same stuff that the GM dealer sells for much more.

                          I run this in the manual transmission of my road race car (Mazda RX7) and it works great. I had switched to a synthetic that everyone was raving about and went back to the Pennzoil Synchromesh. Shifts are smooth and consistent throughout a long run on track. With the synthetic, I was getting some notchy feel when downshifting into second and even convinced myself that I had a worn synchro. Going back to the Pennzoil Synchromesh cleared it all up. I won't stray again!

                              I'm happy to help, Jenc! According to the specifications I have for your 1996 Volkswagen Cabrio, your transmission requires synthetic 75W-90 GL-4 or equivalent. This Pennzoil Synchromesh manual transmission fluid is not synthetic. Royal Purple Part No. 01300 is synthetic and although it is a GL-5, Royal Purple states that their formulation does not harm yellow metals.
