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? ****

Any help would be greatly appriciated.

I added more questions to my post

Before someone else gets touchy on the matter, next time try and conduct a search using the SEARCH button and typing in "tranny id" or "5-spd", etc. before asking questions. This topic has been covered forever.

That said, early 5-spds look like 4 spds but later 5-spds ('80-83) only have one rear mounting tab. For an unknown tranny you would need to either try to run it through the gears or take it apart.....

The 4 speed pulled from my '72 has a plate on the top of it next to the reverse light. The 5 speed has the switch mounted elsewhere and no plate on the top. The 5 speed showed up at a Z shop on a palate from Japan in the mid 80's so it is probably from a Nissan pickup in the Japanese market.

And the 5-spd shown is a 280? (hint: apple starts with this letter). A ZX 5-spd only has one tab in the rear tail (280b tranny).

The 80-83 (84 if you count the RWD Maxima) has one tab but the 79 ZX still has two tabs like the 77-78 280Z...
