My Elise (2006) is put away in the garage for it's first winter. I decided to change the Transmission's Gear Oil in addition to changing the Engine Oil.
Before jacking the car up, place the Elise in gear and engage the handbrake, place wheelstops ahead of the front wheels.
The Elise has been carefully jacked up on one side using a floor jack with wheels (important so that it 'follows' the chassis as the car is jacked up) and a hockey puck. Rhino ramp was placed under the rear wheel, lower on ramp and repeat for the other side. My aluminum jack has a 3" height at its low range.
Remove the service panel only as you would for a regular engine oil change, the rear diffuser can be left in place. I took my service panel out from underneath the car to clean and wipe it down.
Be sure to identify the transmission drain and fill plugs, you don't want to accidently loosen the wrong bolts!!:
Drain plug - the one with 'Read Owner's manual sticker:
Fill Plug - the one with the small pink mark next to it. This is basically what you'll see when your under the car looking up, your head will be near the driver's side rear wheel:
Loosen the fill plug first. Do not fully remove - just enough to let some air in.
Then loosen the Drain Plug, have a pan ready to catch the gear oil when you remove the drain plug. Although I was concerned it would hit the rear diffuser it did not. As the gear oil comes out you can fully remove the fill plug.
Clean fill and drain plugs. I got new crush metal washers from Toyota. These were so cheap I decided to get 2 pairs for a future change.
I got the torque wrench out:
Re-install the drain plug and torque to 29 ft lbs. I used a 24mm short socket with a extension so that the head of the torque wrench can clear the cables that are near the plug (see pic).
Now the fun begins, make sure your fill plug with new washer is handy. I use a small plastic hose hot glued to the end of a gear oil bottle's cap. Then I just screw this cap with hose on the end of a gear oil bottle (Mobil 1 75-90W Synthetic), elevate the bottle and install the hose into the fill hole and squeeze the bottle, I can get more than 3/4 of the bottle into the transmission each time. A few times doing this and I can see the gear oil coming out pretty fast from the fill hole. I know it's pretty full now so I re-install the fill plug (17mm) and torque this to 29 ft. lbs. It took in about 2.3 to 2.4 quarts of gear oil.
Be sure to use your fingers to start the drain and fill plugs back into the holes - you can prevent cross threading this way because you should be able to feel the plug threading back in smoothly. Sometimes I turn the bolt counterclockwise until I feel a small click (the beginning of the thread), then start turning it clockwise and it usually threads in correctly.
It was pretty easy - be prepared with some rags and you may want to wear some latex gloves to keep the gear oil off your hands and wipe up any droppings. Check for any leaks, wipe areas with rag. Your done! Spend a few minutes and admire the engineering from below the car.
