ID this trans?

[mbarjbar]

Can anyone identify this tranny. Tail is marked 5W71C, body is marked TA71B. I will try to post pictures.

Z31 non turbo.

[mbarjbar]

That would be for a 300ZX, right?

Yes, a Z31 is a 1984 to 1989 300ZX.

So, bottom line is that this will not work for my '70 L24 without a lot of major work. Thanks the help.

It has been done but does require some machine work and fabrication. You can use a 5W71C transmission with a 280z-280zx bellhousing to fit the transmission to your L24. It would require some grinding on the bellhousing to clear the front gears on the input and counter shafts and swapping the front counter shaft bearings. Also you'd need to put the bellhousing in a mill and drill out the 5th/reverse shift rod hole to 16mm from 14mm. You'd need to make a trans mount and a longer driveshaft since this trans is 2-3 inches shorter.

How about these two trannies? The top one is an automatic and the bottom one looks to be a 5 speed from a truck, but can it also be used in a Z car?

I know what pair you are looking at, Mike, and the price is right. Sell the auto to that outfit down in CA and you're golden. If they were down here I'd already have them.

I believe the truck tranny will bolt to any L-series motor, but that the truck ratios may be a bit wider than most Z owners want.

If it's a 620 trans it's the same length as a S30/S130 trans. If it's earlier or later i.e. 521 or 720 it will either be too short or tilted wrong.

Yep, that was my plan Arne. I don't need the five speed, but if anyone does they could have it very cheap.

Zeus88, wow, that was over a year ago! Sorry but I never got those transmissions. They were on the Seattle craigslist, but the seller flaked out after I arranged a time to come and pick them up.
