What is the best transmission for the Ford Ranger?

I recently purchased a Ford Ranger and I'm considering upgrading the transmission. What is the most suitable transmission for off-roading and heavy-duty towing? Any recommendations?

The Ford Ranger comes with either a six-speed manual or a 10-speed automatic transmission. If you're planning on doing a lot of off-roading and heavy-duty towing, I would recommend upgrading to the 10-speed automatic for its smoother shifting and better torque handling.

I've been a Ford mechanic for over 10 years and I've seen firsthand the benefits of upgrading the Ford Ranger's transmission. In my opinion, the 10-speed automatic is the way to go for improved performance and durability.
