The GM synthetic fluid. It's really high though.
So...say I were to go to Auto Zone or O'reilys?
Not sure what they have that's equivalent. Someone does though.
I know they sell a sycromesh an additive
Synchromesh is manual transmission fluid.
Whoops! I was meaning LSD additive, but I'm pretty sure mine doens't have that.
They don't need additive if you use the proper $30 per bottle GM stuff.
I just called O'Reilys and they have the 80-90W Lucas and Royal Purple. Which ones better?
i use royal purple..... but thats just a thing that i do... all pluids in my truck are RP..... if its better or not i dont know
