Swepco 201 Gear Oil, 80/90

Swepco is literally what top auto repair shops for high performance vehicles have used for decades for transmission gear oil. Using Swepco 201 eliminates many transmission problems that could otherwise be misdiagnosed as mechanical problems. It is much better than factory oils or other manufacturers' "transmission fluids".

I stated with this oil in my transmission and was happy with it. It was difficult to find when it was time for an oil change so I went with a competitive product from Germany. The transmission was horrible to operate. I managed 6 months with that oil until I found this on Amazon. I'm so happy to a have my transmission working properly again

Nice to be able to source this in Canada for a reasonable price.

Perfect for c style synchro. Most other oils designed for borg Warner synchro.

I researched a lot of transmission oils. This was highly recommended and I agree with other recommendations. My gearbox shifts better and runs cooler on Swepco 201. It is more expensive than the 'average' oil but worth the additional cost for its superior performance.
