I never thought that changing the manual transmission oil in my BMW 330i to synchromax would make any difference. Unbelievable difference in the smoothness of shifting! I will definitely use more of their products in the future!

I have used redline in my M3's transmission for few months, but there was a major difference in shifting after replacing transmission fluid with RP synchromax. Gears are alot smoother and easier to shift even with a short shifter. I will try other RP products in the future for sure.

If you have a 6 speed (NSG370) TJ or JK Wrangler, you should switch to this as soon as possible. You will get smoother shifting, and less metal shavings (wear) stuck to the magnetic drain plug. Been running this in my Wrangler for 30,000 miles now. It's as easy as an oil change. You need 14mm and 17mm hex sockets. One is for the drain plug and one is for the fill plug. You can squirt it in the tranny using the bottle. When it starts oozing out of the fill hole, you can put the plug back in. You'll need 2 bottles (1.6 liters).

Don't forget to also change your diff fluid regularly (every 2-4 oil changes). If you're lazy you can just pump the old fluid out, but I recommend taking the diff cover off and doing a thorough cleaning with some brake cleaner, towel, etc. To do that you need four liters of Mobile 1 75w90. Remove the diff cover bolts, then hit it with a soft hammer (rubber/plastic) until it falls off. Use a razor to scrape the old gasket material off of the diff and diff cover. Be careful not to scrap the metal. Clean everything well with some brake cleaner. Squirt a nice bead of black gasket maker around the diff cover, then reinstall it. Tighten in a star pattern to get a uniform seating. Don't overtighten it. Allow it to dry, then fill it just like you did with the tranny. You might need a small pump though if your Jeep isn't lifted enough.
