I lost 1st and 4th gear while on the freeway.
hooked up my diablosport tuner and it showed a transmission error code po700.
What exactly might that be?

P0700 transmission control module is requesting check engine light from the ECM
need to scan for tranny codes
as it will pin point on what it is going on
