SuperDave1965 Posted July 20, 2010 Share #1 Posted July 20, 2010 (edited) I was just wondering if there is any way to tell the difference in a 4 or 5 speed from a Datsun Z car,just by looking at the case? I have two transmissions. I have a numbers that are stamped in the bellhousing portion of the trans. As near as I can tell it's 763T007 ? The other one that I have has the numbers 7115512. **** Is there anywhere that I can just look up these numbers? **** I added some pics. I have two transmissions that look to be identical. There are pics of both of them. Any help would be greatly appriciated.

Zed Head Posted July 21, 2010 Share #2 Posted July 21, 2010 This might help you determine what type of five speed you have, if you have one - http://www.geocities.com/inlinestroker/ratio.htmlBut I think that if you have an early manual (early 70s to 79) you just have to put the shifter in and go through the gears. The four and five speeds used the same housings.

zKars Posted July 21, 2010 Share #3 Posted July 21, 2010 The housings are not the same. tHere are very distinct differences. Didn't we just discuss this the other day on another thread?

Zed Head Posted July 21, 2010 Share #4 Posted July 21, 2010 The housings are not the same. tHere are very distinct differences. Didn't we just discuss this the other day on another thread?The topic pops up often. I was under the impression that there are differences in things like the speedo gear hole or the top gear switch boss, but that these differences were between years. But that some housings were the same for four and five speeds, hence my suggestion to go through the gears. I would guess that if you had a housing with a top gear switch and a reverse switch and the housing looked like those used in 1976, you could be relatively sure it was a 1976 four speed.To be honest, I have seen lots of discussion on this topic but I have not seen one complete definitive explanation. Just odds and ends. Maybe it's out there but I have missed it. A year by year description with details would be great.

A full length shot of the passenger (right) side of the transmission should do it.
