Welcome to EM! I don't think the number of speeds matter. What's important is the gear ratio of the top gear. Also, in your case I don't know if the "final drive" ratio is part of the tranny. I am guessing it is part of the tranny because you have a FWD. Here is what I did on my car :

I could do this because the trannies were otherwise identical. My car didn't come with the economical tranny, so I just swapped in the 5th gear and was ready to go.
