Is it necessary to change the automatic transmission fluid in a Ford Transit Custom?

I currently have a Ford Transit Custom with over 100,000 miles and I'm wondering if I should change the automatic transmission fluid. I've read mixed opinions online, some say it's important while others say it's not necessary. What do you think?

Yes, it's important to change the automatic transmission fluid in a Ford Transit Custom, especially if it has over 100,000 miles. Over time, the fluid can become contaminated with debris and lose its effectiveness, leading to potential transmission issues.

Changing the automatic transmission fluid is not necessary in a Ford Transit Custom, as long as it has been regularly maintained. However, if you notice any unusual symptoms such as delayed shifting or loss of power, it may be a good idea to get it checked and possibly change the fluid.

I suggest changing the automatic transmission fluid every 50,000 miles in a Ford Transit Custom, regardless of what the manual says. This will help keep your transmission running smoothly and prevent any potential issues down the road.
