* Improved Sealing and Reduced Leaks: The sealed system minimizes the chance of leaks and fluid loss through a dipstick tube.
* Precise Fluid Levels: The sealed system often has a specific fill level determined during manufacture. Checking and refilling with a dipstick is subject to human error and potentially imprecise readings.
* Improved Design & Fewer Moving Parts: Removing the dipstick simplifies the transmission's design and reduces the number of potential points of failure.
* More Precise Fluid Management: These systems frequently rely on sensors and computer controls to monitor the fluid level and condition, providing more accurate information than a dipstick could.
Essentially, the manufacturers opted for a more technologically advanced, sealed system deemed more reliable and less prone to leaks and inaccuracies than a traditional dipstick. To check the transmission fluid in a 2007 Jeep Liberty without a dipstick, a specialized procedure, potentially involving a scan tool to read transmission fluid level, or other diagnostic techniques may be necessary, ideally performed by a trained mechanic.
