I need info of 4 speed final drive & 5 speed tranny. Any idea? The a/t final drive fit in the m/t tranny? Any info of a/t final drive?
I'm not aware that a four speed was ever available in a US market B11 Sentra. It wasn't until the B12 models that they only gave us the four speed in the lowest cost "Standard" model.

The B11 RS5F30's came with anything from 3.55 [diesel], 3.65, 3.79, and 3.89. Nismo used to offer all of those, plus 4.06, 4.17, and 4.47. Back in the day I bought two sets of 4.17's and one set of the 4.47's. I still have one set of the Nismo 4.17 final drive gears if you'r looking for a set. The 4.47's are currently in use in my B11 euro-rally car and I love them!

I also had both the option #1 ultra close ratio gearset and the option #2 middle close ratio gearsets. I blew them both up and there are no replacement parts for them. Other B11/N12 racers had the same problem. They must have been heat treated all wrong because they were really fragile. Stock gears have never broken on me!

Lastly, A/T final drive is completely different than the M/T.

Hi mike!

You have the 4.17' available? You have the a/t final drive number? I want the 4.47 but is imposible found this.

Thanks!
I have to locate them and make sure the 4.17's aren't in a trans right now.

What do you mean by A/T final drive number? If you want to put final drive gears in your manual trans, you need manual trans gears. The A/T stuff is different.
