The 99 model civic in Pakistan had a hydraulic trans with electric lockup, its controlled by the 2 solenoids on top of the transmission, check their resistance - they are 1 amp circuits, so you should have no more than 12 ohms resistance on both.
One is for partial lockup and the other is for full lockup - check them. You will also need to check the wiring to them.
Is the transmission shifting through all 4 ratios?
