What lube do you guys recommend in a FD tranny that's street driven almost daily? I changed to Mobil 1 and now the tranny groans when shifting above 5K. Not a grinding with a grinding vibration in the stick... but more of a groan. It will grind if you try to force it while it makes this noise. Is it possible that the Mobil is too slick and the synchros can't match the gear speeds? I have heard Redline is good. What do you guys think?
Thanks,
Don.

 

Redline 75W-90 is what I use in my '89 T2. Good stuff indeed.

My car is pretty much the same symptoms not as bad but i emailed redline and they said to use there mt-90...so use whatever weight you want but the mt-90 is supposed to do the trick.

 

Lethal,
Did changing the fluid help?

no i didnt change mine yet..but we did do the same switch in another one of our cars and it did make an improvement. soo yes it will make a difference.. let me know if you do yours first or ill get back to you.

 

from mazdatrix and so far no regrets. i heard its good ****, but kinda expensive though.

 

I've heard NEO too. I've got it to go into my car. Another car I drive was much improved after putting the NEO in it.

 

i tried redline and amsoil. redline seems to be a better choice.
