The "S" light flashing...

[PROBLEMATIC]

Ok, I've a 91 accord, it's automatic. The "S" (sports) light on the panel starts flashing when the car warms up (like 5 min after I turned on the car). When it's running, the tranny changes from 1 to 2nd abruptly, sometimes it don't wanna grab the 2nd and from 2nd to 3rd always it feels like slips a lil bit (accelerates like on neutral gear 1 or 2 secs) . I recently changed both solenoids and I was thinking to make a transmission fluid change to fix the gear problem, but I dont know really what the flashing "S" means and how could i fix those problems. Please help, thanks.

The flashing S light indicates an error code in the TCU (transmission computer).

If your TCU was bad then yes this would fix his problem. He needs to figure out what code it is first before pulling the TCU out. Once he has that information then he can properly diagnose the problem. dakiid listed the proceedure and the list of trouble codes.
