Just like before, continue adding more transmission fluid until it begins to overflow. Using safe jacking practices, get your car up in the air once again. To determine if your car is properly up to temperature, use an OBDII scan tool that outputs this data. You can find this temperature listed on the side of the transmission oil pan. Do this until your car is up to optimal temperature. With the car on the ground, you want to firmly apply the brake pedal, put your transmission in gear and run through all the gears. Unfortunately, this next step requires you to take the car off the jack stands or your lift.

Now you can loosely install the fill plug. You want to fill the trans until it begins to overflow. A fluid transfer pump would work as well in this scenario. We highly recommend using this syringe as the fill plug is difficult to access. Using our fluid transfer syringe, begin filling the transmission. There's nothing worse than going to fill the transmission and watching oil spill out all over your garage floor. The new pan in the kit has it pre-installed, however, it's worth checking. Once they're all tightened, it can't hurt to go around in the same order one more time to ensure that none loosened up.īefore starting the fill procedure, make sure the drain plug is installed. The image below demonstrates the correct order. From this point, you can follow the torquing procedure and torque all the screws to the specified 10N Holding the pan in place, start all the T40 Torx screws by hand until they're just snug. Before installing the new pan, make sure to lubricate the o-ring to ensure proper sealing. Since our F30 comes with the plastic transmission oil pan, our kit comes with the new pan that has an integrated filter. Simply use a lint-free rag or shop towels and make sure there's no debris or significant amounts of old oil. Without doing this, you risk having leaks - either immediately after completing this job, or not too far down the line. Often an overlooked step, cleaning the mating surfaces for the new transmission oil pan is mandatory. Once you drop the transmission oil pan, be sure the o-ring comes off with the pan. By leaving the screws opposite of the drain plug in place, you can drop the drain lower to more effectively drain the oil. Using a T40 Torx bit, remove the twenty-four transmission pan screws. Step 4: Remove Transmission Pan Screws and Remove Pan Now you can place your fluid catch pan under the transmission and remove your drain plug using a 10mm socket. Doing this creates a vent and allows the oil to flow more freely. Step 3: Loosen Trans Fill Plug and Remove Drain Plugīefore you start draining the oil, loosen the trans fill plug using an 8mm socket. Make sure your car isn't hot since you'll be working around the exhaust. The heat shield is held in place by three 13mm bolts. Then, using a 10mm socket, remove the remaining two bolts.
Using an 8mm socket, remove the eight bolts that hold the trans skid plate in place. Step 2: Remove Transmission Skid Plate and Heat Shield If using stands, place wood blocks or spare wheels under the car as an added backup. Whether you are using a lift or completing this job on jack stands, take every precaution to make sure the car is secure. Here at FCP Euro, we have the luxury of an automotive lift. If your transmission is shifting slowly, sloppily, or it's overly loud, these are good signs that it's time to perform a transmission service.
