* Transmission type: 2001 Wranglers used several different transmissions (manuals and automatics, with variations within those). Different transmissions have different inherent strengths and weaknesses.
* Maintenance: Regular fluid changes, proper lubrication, and addressing any issues promptly significantly extend transmission lifespan. Neglect leads to premature failure.
* Driving style: Aggressive driving, frequent towing, or off-roading puts far more stress on the transmission than gentle on-road driving.
* Previous repairs: A transmission that's had prior repairs might be more prone to future problems.
* Overall vehicle condition: A well-maintained Jeep overall suggests better care of the transmission, as well.
While some owners might get 200,000+ miles out of a Wrangler transmission with proper care, others might experience problems much sooner (even under 100,000 miles) due to the factors listed above. It's not uncommon to see issues arise between 100,000 and 150,000 miles, but again, this is highly variable.
Instead of focusing on a specific mileage number, focus on regular maintenance according to the owner's manual. That's the best way to maximize the life of your Wrangler's transmission.
