5 Speed transmission Swap Questions

[kevingorby]

Hi guys. Need to pick your brains. I have picked up a nice 5 speed transmission and was told it was out of a '78 or '79 Z. I want to swap it with the 4 speed original. I was told it would be a direct swap, but I have found 2 differences with the 5 speed right off the bat. First, there is a sending unit with 2 yellow wires located near the shifter on the right upper side (in addition to the back-up light switch). Second, the speedometer cable attaches on the left side (instead of the right side) with a 45 degree down angle. The 5 speed serial number is 7Y04342. It is stamped ZL 71B with a #1 stamp below that. Your help is appreciated. Kevin

I'm pretty sure you were told wrong, and I saw your post on zcar, I agree that it's most likely a truck trans

Thats correct not a Z transmission. Most likely a Datsun 610 transmission.
