has anybody performed the ls 5th gear into a b16 tranny?

i’m seriously concidering this mod… out here in fl theres nothing but highway roads and its killing my gas milage… also doin 4500rpms constantly cant be healthy for my ls/vtec… is it an easy swap?? thanks in advance

I know a couple of people on here have done it before because I’ve asked this question on here myself. I plan on doing it for the same exact reasons you are. It’s the only reason I still have my LS tranny around. As far as how to do it, I don’t know, I’m gonna have one of the techs here at work help me with it so I don’t screw it up.

I did it by myself in my garage. You will need a 32mm socket to remove the nut on the secondary shaft (also for the axle nuts)and a gear puller (slide hammer type) to remove the bearing and gears. You will also need a c-clip spreader to remove the case. It is a good idea to replace the tranny seals and clutch while the tranny is out.

With the LS 5th I can cruise at 80MPH at very low RPM’s

I did it with my hydro GSR tranny. Even a lowly stock n/a LS is fun with that setup. :wink:
