What is the best tranny fluid for the G-50?

[Jeff]

Is Swepco the best fluid for the G-50 or is there a better one out there? Any experience with Redline?

The consesus on the board seems to be synthetic fluid for the G50. I have to say I agree with this from my personal experience.
Currently I'm using Redline's fluid that I installed in the spring.

It shifts better with synthetic fluid, especially the 1st to 2nd shift when the transmission is cold. This shift was very slow with Swepco.

Swepco is best for 915's. I have Mobil 1 in my G50.

i recently replaced the fluid using mobil 1 and the shift from 1st to 2nd got much smoother.

Thanks Guys. I will try Mobil 1 or Redline when I change my reverse light switch.

I too am using the mobil 1 in my G50 but what is the reason the G50 shifts a bit rough when cold? Never experience this in other manuals. Once it is warm, the shifting is very smooth.

Swepco doesn't work as well on G-50 as on 915. I switched to Redline and works very well.
