I have strayed a time or two but I always come back to this. The shifting is always so much smoother when I have this in the primary. Worth it.

Best transmission oil for a performance transmission. Shifts way smoother and less noise with Spectro

This oil is a decent oil. I still can’t get SPECTRO to answer a question about their “oil packages content”, and if the packages are added (blended) while the oil is being made. Adding packages to the oil after it has been blended is not a good way for the oil to provide the maximum protection claimed.

I could not find this product with any local vendors but I managed to find it online and it arrived in a rather short period of time. I used this oil on the main primary of my BigDog Ridgeback Chopper and this was after doing quite a bit of research and bottom line is you want to use a good product that will not cause you headaches down the line. I highly recommend this product because it is reliable.
