QuoteOne plug is the actual fill port, and the other is a fluid level / inspection plug.
Why Toyota did this
The MR2 Spyder's mid-engine layout means the engine and transaxle sit at an angle, not perfectly level like in many front-engine cars. Because of that:
• Filling from a single hole could overfill or underfill the transmission.
• Toyota added a level-check plug so the correct fluid height can be verified regardless of the car's orientation.
How it works (manual transmission)
• Upper plug → Used to add fluid
• Side/lower plug → Used to check correct fluid level
• When fluid just begins to drip from this plug, the level is correct[/
