If you had to choose between these two obviously choose 75W-90.

However, I highly recommend using GL-4 oil:

A lot of transmissions these days run completely fine with GL-5 gear oil, but older cars like 240s have transmissions that are more suitable with GL-4 oil. Im currently running that exact Amsoil GL-4 oil in my tranny right now. Basically, some of the chemicals in GL-5 oil that aren't present in GL-4 oil slowly eat away at the synchros in your transmission.

Something in your transmission that is slowly being eaten away doesn't really sound like a good thing.

Glad to see another person using Amsoil gear oil for their tranny fluid though.
Thankyou sir.. i will be ordering today.
