In the next couple of week my MR2 is having all her fluids replaced

new sparks, new rocker cover gasket, new dizzy and rotor arm and her paint work sorted all in the name of JAE.
What I need to know is what oil do I need to replace the old stuff in the gear box?
Kiya is an Auto Import N/A 1990 G-ltd MR2!
TIA
Ash.
