Weber State University (WSU) - Department of Automotive Technology - Transmission Lab. This episode demonstrates the fluid level checking procedure for the ZF 8HP45, 8HP70, and 8HP90 8-speed automatic transmissions used in select Chrysler, Jeep, Dodge, RAM, HellCat, BMW, and other brands of vehicles.

Additional Information:
- Please turn off your traction control system before performing this procedure.
- ZF recommends safely tilting the vehicle towards the driver's side to add an additional 0.5 liters of fluid to compensate for the transmission cooler bypass valve issue discussed in this video.
- You must use the correct fluid in this transmission. The fluid must meet ZF-LIFEGUARDFLUID 8 (ZF No. S671 090 312) specifications. See https://aftermarket.zf.com/remotemedia/lol-lubricants/lol-en/lol-te-ml-11-en.pdf

As an automotive professor, I hear from a lot of people and students who have a negative reaction to this video and wonder why they took away the dipstick. Think about this: if a dipstick is so easy to use, you should be able to answer all of the following questions:
1. At what temperature is the "cold" mark accurate?
2. At what temperature is the "hot" mark accurate?
3. What temperature does the dipstick even refer to? Outside air? Coolant temperature? Transmission fluid temperature?
4. How will you measure that temperature?
5. If the fluid is within the cold mark area marks when it is "cold", is the fluid level okay?
6. if you live in a cold climate area like Alaska, is the "cold" level accurate there? What if you lived in a hot climate area like Central America, is their "cold" mark accurate?

If you cannot answer all of the previous questions, should you be using a dipstick?

All transmission fluid expands when heated, you must know what the fluid temperature is to check its fluid level properly. This is not a new concept. It began back in 1940 with the world's first mass produced automatic transmission, the Oldsmobile Hydra-Matic transmission.

Toyota, Ford, GM, BMW, Mercedes, etc. all do the same thing. This is not just a Chrysler thing. See my other three videos: https://www.youtube.com/playlist?list=PLIn3FrDiB1lyLCTQJ8cctlzy5AlAhZFvz
