Default Any experience with NEO fluids for rear diff and or tranny in WRX?

I was looking to go the NEO oil route for both my rear diff and my trans.

I have researched their sight, but not sure if i need the
RHD 75w90 (heavy duty) or the regular 75w90 or what.

I would like to change those fluids out very soon and just need to make a WISE decision that doesnt deteriorate the trans or diff life. I need more protection in the trans!!

Thumbs up

i put the RHD 75-90 in my full doggy tranny. it made a world of difference
the only problem it the price
i think its about 75.00 a gallon
but if it will save a 4k tranny then its worth it

anybody with synchros using this stuff? how does it shift?

am currently using redline 75w90ns and agree with others that it might be too thin -- shifts great cold but a little balky warm -- also increased gear noise in comparison to factory fill.

My experience with the Redline is exactly the opposite of Bluebaru. Shifts easier than stock fluid and significantly reduces gear noise, especially the off throttle deceleration noise present with the stock fluid.
