Hi everyone, has been a while since posting and have since traded the Wrangler in on a KL Cherokee Trailhawk! Thoroughly enjoying it but wanted to work out what to expect RPM wise and if I would ever see the elusive 9th gear.

After calculating it out I am thinking unless I like the chances of loosing my drivers license I will never see 9th 🙁

Anyways, here’s version one of the calculator, hope someone finds it of assistance. If you can’t see it just wait a moment and it will appear.
