To check the transmission fluid level on a 1993 Nissan 240SX, first ensure the vehicle is on a level surface and the engine is running at normal operating temperature. Locate the transmission dipstick, which is typically near the back of the engine bay, and remove it. Wipe it clean, reinsert it fully, then remove it again to check the fluid level; it should be within the specified range on the dipstick. If necessary, add the appropriate type of transmission fluid through the dipstick tube.

Obviously check the oil level first. If OK, then sounds like your oil pump is bad.
