Description: Do you think you know the proper way to use an automatic transmission dipstick? It may be a lot more complex than you ever imagined. This video is intended for students in the online AUSV 2520 Automatic Transmissions class at Weber State University in Ogden, Utah. This class is normally taught face-to-face, but due to the COVID-19 Pandemic, I am attempting to offer the class material online. Suggested quiz questions are shown below the video timeline. TIMELINE: 0:00 Introduction 1:00 Two pages of dipstick instructions 1:40 Preliminary Checks and procedures 2:30 Transmission fluid temperature monitoring 3:05 Cold Check Procedure 4:30 Results of the first cold level check 80 Degrees F (26.7 C) 5:23 Results of the second cold level check 84 Degrees F (28.9 C) 6:20 MUST-SEE: The real purpose of the "Cold" range on the dipstick 7:25 Fluid color and condition check 9:26 The engine warms up quickly, the transmission slowly 9:47 Waiting for the transmission fluid to reach 160 degrees F (71.1 C) for the Hot Check Procedure 10:28 Ran out of gas, Shop Vehicles! 12:15 Unable to drive training vehicles to warm up the transmission more quickly 13:42 Fluid level check after 56 minutes of idling at 144 Degrees F (62.2 C) still too cold. 14:00 Dipstick latch and seal function 16:38 Results of the fluid level check after 84 minutes of idling at 160 Degrees F (71.1 C) 17:09 Hot check procedure 18:08 Interpreting the results of the hot fluid level check 19:38 Must See: Results of the fluid level check after 84 minutes of idling at 170 Degrees F (76.7 C) 19:53 Must See: Results of the fluid level check after 84 minutes of idling at 180 Degrees F (82.2 C) 20:11 Must See: Results of the fluid level check after 84 minutes of idling at 190 Degrees F (87.8 C) 20:45 Video summary 22:05 Results of the cold fluid level check with the engine off 22:40 Some transmission fluid levels are checked with the engine off 23:18 Why the dipstick has been removed on many modern vehicles 23:59 Different types and styles of dipsticks Questions for Teachers: 1. Does the vehicle need to be parked on a level surface or an inclined surface? 2. Does the engine need to be running during the fluid level checking procedure? 3. If the engine must be running, at what engine rpm should the fluid level be checked? 4. If the engine must be running at a specified rpm, how will you verify the proper rpm? 5. If the engine must be off, are there any conditions that must be met before checking the fluid level? 6. Are there any procedures that must be met before checking the fluid level? 7. Does the transmission cooler have a bypass valve? If so, how does it affect the ATF fluid level? 8. At what temperature range should the cold fluid level be checked? 9. At what temperature range should the hot fluid level be checked? 10. What temperature is being referred to in the previous question? Outside air? Coolant temperature? Transmission fluid temperature? 11. How should you measure that temperature? ABOUT US: Weber State University (WSU) - Automotive Technology Department - Automatic Transmission Lab.
