5spd gearbox codes

[g72s20]

I would like to confirm just what the gearbox is.

So...how are the boxes identified, and whereabouts on the box

are these codes you speak of??

Once again thanks guys.

Due to a maze of circumstances,(the facts are stranger than fiction, but probably familiar to you guys!) nothing will happen in a hurry, but, Datto Zed I will try and get some shots of the Prince in its current state, which is about 90% done.

Sometimes they were marked clearly on the bellhousing or on the body of the main case, but sometimes not at all.

I've seen quite subtle part number prints ( in what appears to be blue ink ) on them, and also number stamps on the top of the bellhousing or on the main case. The blue ink stamps can just about disappear over time. It seems that some of them were not clearly marked at all.

Of course, its fairly easy to identify the "Dogleg" shift direct-drive trannies from their shift pattern ( even out of the car ) but pinning down its exact ratios can be difficult. The only sure way to do this is to take the guts out and start doing tooth counts. That goes for all the non direct-top close ratio / competition boxes too.

Thankyou Alan, once I get a good look at the case I'll let you know what I find.

Regards,

You are welcome, Jim.

If there is no other way of identifying what you have, and you are forced to do a manual tooth count of the gears and counter-gears, then give me a shout. I have all the data for this from official Nissan publications. Its a horrible job, but its the only way to make 100% sure of what you have got.

Good luck,
