Why is my Ford Transit Custom making strange noises when I accelerate?

I have a Ford Transit Custom and I've noticed that when I accelerate, it makes a strange noise. It almost sounds like a grinding or rattling noise. What could be causing this? Is it something that I need to get fixed right away?

From your description, it sounds like the issue could be with your transmission. It's important to get that checked out as soon as possible to avoid any potential damage.

It could also be an issue with your exhaust system. Have you noticed any decrease in performance or strange smells coming from your vehicle? It's best to have a mechanic take a look at it.

I had a similar issue with my Ford Transit Custom and it turned out to be a problem with the fuel injectors. Make sure to get those checked as well.
