What should be my RPM at 70 mph. Does this transmission have a lock up converter for the overdrive or is it a true fifth gear?

Not sure about the rpm, there are online calulators that will tell you.

Overdrive and lockup converter are two different things.
Everylate modelautomatic transmissioni know of has both.
