Thread: How to: Fix your P11/B15 tranny with QG18 gear stacks! 56K no.

does any one know if the b13 lsd is the same as the b15 lsd minus the ring gear>


found out they are the same....

any one knows how many teeth on a b15 ring gear and how many teeth on a p11 ring gear. i am getting 71 teeth on my ring gear which happens to be the same teeth count on my b13 diff. so i am going to assume that i have a p11 transmission and not a b15 as i was told.

Whats necessary to change just the bellhousing? I hoping it doesnt require the full tear down process

My rear mount broke and caused a break in the bellhousing.

full tear-down unfortunately. Gotta pull stacks out of the bell housing and put them in new housing

Are the shifter forks the same from both trannies? Incase you have a b15/p11 trans with bent shifter forks inside the tranny.

In this pic, can u see 1 check ball in each side slot? Or is it just the glare from the flash?

just glare from the flash. This is with all the check balls removed.

What about the torque specs for everything?

edit./.. got past that part

For those who couldn't find the torque specs- http://www.nicoclub.com/FSM/Sentra/2001_Sentra/mt.pdf

I bought an LSD P11 box from Andreas and the pinion and ring gear were thrashed. He sent a new pinion shaft and ring gear but the ring gear was just a little smaller. Miko said he didn't remember where they came from but I thought he mentioned a QG.

I figure my final drive is taller since the ring gear is smaller and the mating gear on the pinion shaft is bigger. Either way it's a nice match for the VE in the G20. 1st has more to give.

Nice write up. Also, I find that I can use the pin punch to easily remove the shift rods by pushing the punch through the pinhole while rotating and lifting up on the rod.
