Now you’re close, weigh a clean glass beaker, add slight more oil than you need to make up for the cling losses and pour in little by little reweighing often until the fill is accurate down to the gram of what come out at the service. Once you poured it in, reweigh the container and funnel to see how much oil you lost as residue coating the inside the those. Clean everything, weigh a clean oil filling jug and funnel then add your fill of oil to the engine. We also had a dry and clean wet values of oil filters to compensate for how much oil those held. Add the tool, glove, container oil weights for your total value. Weight your container of oil and subtract the empty weight to get the oil weight. at 20 minutes install a new drain plug and crush washer and torque to spec. Get the engine oil to a specific temp, pull the oil drain plug and catch the oil, while letting it drain and drip for 20 minutes exactly weigh your dirty gloves and tools and subtract the initial weight to see how much oil transferred to those. You weigh an empty container and your clean gloves and tools. Every routine maintenance the oil would be weighed and the same amount that came out would be back in down the gram. After that it was never filled until the oil level warning light came on. At start of test the cars would get the oil set to full at a specific oil temp. When I was doing quality testing and development the test cars tracked oil consumption. If you’ve ever weighed fluid it’s so f’n tedious! Let me know if you have any questions.Ĭlick to expand.That’s a lot of assumptions just to avoid actually setting the fluid level. See the video for detailed views and to get a better understanding of everything. Once it slows to trickle put the check plug back in with a new crush washer and you’re done. If no fluid comes out the fluid level is too low. When transmission fluid temperature reaches 100-105 degrees 100-105 degrees (official Toyota specification is 40-45 C which is like 103-113 F) let it idle in park and pull the check plug back out of the transmission pan and let the excess fluid drain out. You can let it idle in gear or gently brake torque the engine to build up temperature in the fluid faster. Then let it idle in park and monitor the transmission fluid temperature. Shift from park, to reverse, to neutral, to drive, then back up through the gears to park and repeat a handful of times, just a couple seconds in each to help circulate fluid. **Setting Transmission Fluid Level** On level ground start the engine and let it idle for 15-20 seconds. Remove the fill plug and add transmission with fluid using whatever method you choose. Reinstall the transmission pan with the new gasket making sure to start each bolt before tightening any of them. Using lint-free rags, clean out the inside of the transmission pan, the magnets in the bottom of the pan, and the gasket mating surfaces on both the pan and the transmission itself. Push the strainer up into place while gently rotating it back and forth to avoid pinching the o-ring. Use transmission fluid to lubricate a new o-ring and install it in the strainer. Unbolt the transmission fluid strainer and wiggle it off, this will release more fluid that will drain out the bottom of the filter. There will be quite a bit of fluid still in the bottom of the pan. With a rubber dead blow hammer gently hit the transmission pan sideways to break it loose and remove the pan. Unbolt the transmission pan leaving one screw loosely installed at the front and one screw loosely installed at the back. **Replacing Transmission Fluid Strainer** Move onto replacing transmission fluid strainer, or to directly to filling transmission fluid. After the fluids drains put the drain plug back in with a fresh crush washer and tighten it. You always want to do it in that order because if the fill plug won’t come out or the hex on the check plug is stripped you want to know that before you drain all the fluid and the vehicle is no longer drivable. There are 3 plugs (drain, check, and fill), loosen the fill plug first, loosen and retighten the check plug second, then remove the drain plug completely. Make sure the vehicle is cold and on level ground.
