What oil in ba5/10 transmisson?

What type oil do I need to run in a ba5/10 transmission that has around 100K miles?
I think that the original specification was for ATF, but I believe a thicker oil would work better in this transmission.
What do the experts suggest?
thanks
steve

You need to use a GL-4 spec, if I remember right. GL-5 has too much sulfur in the additives, and sulfur and brass syncros do not get along. I think you can still get GL-4 from AMSOIL guys.

Rob you're thinking of the AX-15. Far as I know, any 75/90 will work great in a Peugeot.


ATF is for autos and some t-cases.
