BG Syncro Shift® II is a specially formulated gear lubricant designed for front wheel drive manual transmissions. It reduces maintenance costs by improving thermal stability, low-temperature fluidity, and shear stability while providing smoother shifting and improved seal compatibility.
Automatic transmission fluid and other light lubricants are often recommended for use in transfer case, manual transmission, and trans-axle applications. Because these fluids are light viscosity, low film strength fluids they do not fully protect all components. Manual transmissions and trans-axle applications induce severe fluid shearing, greatly sacrificing wear protection.
BG Syncro Shift® II Full Synthetic Gear Lubricant is a professional-use product designed for manual transmissions, trans-axles and transfer cases. It provides unmatched film strength, wear protection, exceptional mechanical shearing resistance, and excellent low temperature fluidity. All this without sacrificing any performance characteristics.

Just do it.
I wanted peace of mind knowing that the fluid was swapped and not low for whatever reason.
Jacked up passenger side to get as much fluid out as possible. Used a pump and used both quarts per direction. Can also be done with an hose that is 1/2 inch OD. Also installed the new magnetic drain plug which was a must for me anyway since mine was getting a tad rusty.
Swapping was easy. Decent amount of YouTube vids, just be sure to use both quarts. Shifting feels smoother, no issues getting into first like I previously had (when it was cold) but I also installed bushings and short throw adapter at the time.
TL;DR
-Now the trans will have correct amount of fluid.
-exceeds OEM specs
-new drain plug is a nice touch
I’m not one to make a big deal out of a transmission oil. But this oil made the shifting so much smoother.. especially at those higher rpm’s ;). I can assure you it’s well worth the money.
Reading the the reviews here, I wasn't sure if this would actually make a difference or if it would be a placebo.
I had already done a Mountune short shifter and Whoosh bushings, and engagement felt solid. I went ahead and bought this fluid since I got the car at CarMax and who knows what they put in there, if not the last owner.
Day after the fluid change I made a 700mi trip, and I do believe it actually does "feel" better. You know that satisfying pop when you're putting the last corner of your phone case on? That's how the shifts feel. Every gear has a very satisfying plop feel to it.
If it's all in my head, well 5 stars anyways for the always fast shipping, and product performs as it should lol.
Idk what folks are saying about feeling an immediate difference. It feels the same. It shifts. It shifts the same. It's transmission fluid....my transmission hasn't grenaded so I assume it's working. That's that. I'll give it 5/5 for the magnetic drain plug and exceeding OEM specs. Thanks whoosh!
Certainly smoother shifting but the important part for me is determining how it fares under WOT. Whatever fluid that was in previously was relatively new since it was still transparentish. Under consistent WOT, it was noticably underperforming, shifts felt...rubbery and transaction in gears wasn't seemless, not quite rev hang, but something along those lines. This eliminated all the aforementioned characteristics. And likely a dominant contributing factor to beating a friend's stock Evo 9 in 1320. By A fender. 😁
At the time, e30 Dizzy tune; Mishimoto induction hose; Ramair drop in filter; and MRBP 3" catback exhaust.
