Hey guys its been so long and i cant really remember what it all means so hopefully someone can help

Lookin at eaton and fulle trannies in big trucks anyone remember what the model numbers mean?

Like RTLO16713A
or

RMX10-155A


I know the eaton tranny says its a 13 spd and the fuller says its a 10 but i need help with the rest if you could please

 

I can ask my dad tomorrow he has worked for them for 30 years.

 

See it this helps. He has not heard and could not find out anything about the RMX one.

 

Thanks thats what i was looking for! just couldnt find it. I havent either. I work on them almost every day ( heavy duty trucks. Just couldnt remember as I dont mess with trannies much. and ive never seen a rmx number either, I also thought that eaton fuller was one company who knows.
