8/70 240z transmission question

[Stanley]

Car and Driver ran a favorable review of the Z with AT. It's not gutless if you shift it like a stick. You can also downshift, but it's not recommended over 70mph or so according to the owner's manual, so not good for a road race where you need to downshift for a 90mph curve. Can't burn rubber unless the tires are crappy. With a 2 1/4" exhaust you can get very close to the 1/4 mile time that C&D got with the stick (launching at 6000 rpm with the borrowed car). 119mph top speed compared to 124mph with stick. Read somewhere it's good for autocross where you leave it in first and just drive.

I like it for the quick 60 to 90 mph which is handy on the freeway. Worth it to swap, I don't know.

I would go all the way and put a bench seat and column shifter in there. Then you can cruise with an arm free for your passenger. Haha.

The residual hoses attached to the radiator imply that it's the stock radiator unless someone was getting fancy with oil cooling. Looks like it was a factory auto car.

The typical mod for autos were called "shift kits". I searched the Google and found a few links.

Thanks for the links about the Shift kits. I'm interested, of course, especially since it doesn't sound very expensive.

A little bit of subject, but maybe interesting for some with auto transmissions.

If you want these kits, you should google "Holden VL commadore nissan transmission shifter kit"

In Australia Holden was using the Nissan RB3.0E engines and the 4N71B auto or the 5-speed manual transmissions in the late 85 through to 1988 Holden commadore until the Buik engine plant was ready for production.

The VL was with the Ford Falcon one of the most popular cars in those years. All the auto transmission shops were doing these mods back in those days.

See link in Gumtree. Kind of Craigslist in aussie land.

Here's another thread on shift kits that I just came across. Not that a shift kit is necessary, just posting because automatic transmission threads are few. I think it's the same guy.

A turbo zx auto with a lockup torque converter and one of these shift kits would make a nice desert highway cruiser.
