Mazda Repair: enginer fluid reservoir, plastic screw, flood level

Question
Do you have pictures and diagrams of what reservoir it is in the engine for 90 Miata 5 speed.  It has round reservoir next to Break flood reservoir and there is one by the radiator on the driver side.  How do I check transmission flood level?  There is a leak and it might be low.  Thanks

Answer
I'm having a hard time following your line of questioning.

Miata Main Fluids to Check;

1. Anti-Freeze/Coolant - within the radiator and the reservoir for it, located passenger side behind the headlamp door, checked by sight. (Yellow cap and tube)
2. Power steering - uses Dextron 3 ATF fluid, black metal reservoir located next to the driver's side headlamp door.  Check cold by dipstick
3. Engine oil filled at the valve cover black plastic screw cap front driver's side of the engine.  Dipstick checked cold.
4. Manual transmission, no dipstick, over flow level port driver's side of the gear case itself, you must be under the vehicle to check this.  Uses 75w-90 gear oil.  Fill until oil presents at the port.
5. Rear differential, no dipstick uses an over flow level port located on the housing cover.  uses 75w-90.  Fill until oil presents at the port.
6. Brake Fluid located driver's side at the brake booster/master cylinder sight checked uses DOT3 or 4 fluid (larger reservoir)
7. Clutch hydraulic system, located on the firewall far corner of the driver's side.  Sight cheecked uses DOT 3 or 4 brake fluid. (smaller reservoir)
