Review on 🔧 ACDelco GM Original Equipment 10-4014: High-Quality Friction Modified Synchromesh Transmission Fluid - Reliable 1 qt Solution by James Cash

Works much better than the Honda MTF which consistently crunches 2nd gear 9 times out of 10. Shifting gears when starting the car is also smoother. Only twice the price of a Honda MTF, and at 15km intervals it really isn't that much more expensive in the long run. Overall, this fluid helps the transmission engage and disengage much better than it does on a Honda MTF. If your gearing is grinding or squeaking, I highly recommend trying Synchromesh Friction Modified before switching to Royal Purple Synchromesh or Redline MTL. Do not use a Torco MTF as it is the Gl5 spec and the Honda gearbox is Gl-4. GL5 is too aggressive for synchronization in Gl4 gearboxes.
