How to identify a transmission

[Nate.a.v]

Hi so I just recently picked up a datsun 510 wagon and it came with a extra transmission but unfortunately the owner didn't know where it came from. I've been told from people that it's either from a pickup truck or its a dogleg transmission from the 200sx. I was wondering if there is any way I could identify it.

The shift pattern would be the easiest...

Reverse is up on the left on the dogleg...

DatzenMike would be the easiest.  He will tell you what it is, what vehicle it came out of, and probably the gear ratios.

Looks like a short shaft 5spd to me out of a 1985/86 Nissan 720 regular cab/short box truck.

BTW, it is easiest to tell it is not a dogleg 5spd because it has that rib on top of the bell housing case, dogleg 5spds have smooth bell housing tops(no rib).

Definitely an L series made after '79 and not a dogleg.... doglegs have a smooth bell housing without ribs and there were no L series doglegs after '79.

 

 

Wayno you are absolutely right. This is a 2wd 720 shorty 5 speed with an L series front case swapped on. In the above picture you can see the threads foir the speedometer pinion and the hold down bolt.

Thanks Mike. My second question is would this be hard to bolt onto a l16?

That should bolt right up but you will probably have to modify the rear mount.... it's a great upgrade...

I've been running the same thing behind my L16 in my 521 for about a year now....

It will work but you will need to keep your L16 clutch arm and release bearing collar and use it on the 5 speed. The collar is the thing the release bearing is pressed onto to hold it.

 

You can use your clutch slave and push rod.

 

I think you can still buy a 71B transmission cross member for a 510. Short or long should still have the mount in the same place on the transmission.

 

 

If you have a few tools you can make this handy set of adapters to keep the original 510 cross member by lowering and positioning it under a 71B 5 speed. Hell a fab shop could knock these out for less than the boughten custom cross member.

Great, thanks for the much needed info Mike and Crash.
