Think your Jeep’s transmission fluid lasts forever? Think again.

Here’s how I changed the ZF 8-speed fluid on my 2024 Wrangler Rubicon X (ZF 8HP / 850RE) — following Jeep and ZF service-manual procedures, plus smarter methods ZF never covered.

In this video, I show how to change the transmission fluid on a 2024 Jeep Wrangler JL Rubicon X with the ZF 8-speed automatic (8HP 850RE). We’ll cover tools, torque specs, and step-by-step instructions, plus a smarter way to check fluid level than the factory Jeep/ZF method

💧🔩Fluids & Parts:

• Mopar ZF Fluid / Oil – (Need 6): I’ve had good luck buying this from this Amazon seller - https://amzn.to/457CNDw

• Filter Only — Mopar Part # 68417054AB
The filters sold on Amazon aren’t genuine Mopar. In my opinion, this filter doesn’t need to be replaced every time — I change it about every 60,000 miles. If you do replace it, I recommend buying directly from Mopar, a Jeep dealer, or a trusted parts vendor.

• Pan gasket only – Mopar Part #: 68362042AA: (see comment for “Filter only” above)

• Complete Pan + Filter + Gasket Kit – Mopar Part #: 68362041AC: (see comment for “Filter only” above)

• 5-Liter Measuring Pitcher: https://amzn.to/4qhGi2M
