Hello and welcome to JustAnswer!

The reverse lamp switch isn't hard to change. If you've confirmed it is bad then you shoudl already be familiar with it's location on the right rear of the transmission case, it's number 28 in the diagram here.

The switch simply threads into the transmission case. All you need to do to replace it is unplug it and use a socket or wrench to loosen and thread it out of the case.

I'm unable to edit my post but it should have said the switch was number 22 in the diagram.

Thanks for the answer,but I think the switch is Number 22,
28 is an inner part.

That's correct. I couldn't edit first post so I posted again directly after I sent the picture to clarify my typo.
