I was going to make it long but can't be bothered with guessing games.
I hope this isn't too hard for you.
What make and model and year is it.?
Forget the gear box.

Alternative call up for a diagnostics test from your local garage or a mobile unit if you can't get it to the garage. However don't leave them guessing what vehicle it is.
