Kwikdrft · 09-30-2009, 11:19 PM

ok i got a 1994 nissan ext hardbody truck 2wd AT. it got no reverse but i cant find and transmission for it, but i found a DOHC 240sx AT tran with over drive like truck. but my truck is a SOHC not a DOHC just want to know if it will fit into to my SOHC motor. thanks

The amont of cam shafts an engine has does not tell what transmission it has to have. The bolts on the bell housing need to line up would be good to start but the big thing is the computer needs to talk to that certain trans and if it isn't new enough of a trans reguardless the over drive or not it won't work. Plus the type of trans counts to, the car trans may have a different tail shaft and will not work. Most likely your out of luck for them to swap across. To many variables.

thanks my is a 1994 hardbody and the tran i found was a 1993 240sx tran so the years are close. well it work????

the 240 and the hardbody share the same engines... other than that, i'm not sure. i know that the MANAUL transmissions for the DOHC and SOHC 240's are interchangeable... a buddy of mine has both.. Automatic, I'm not so sure... besides, would a tranny from a car perform well in a truck? wouldnt the gearing be different?

Crmzendrgone · 10-01-2009, 10:11 AM

I guess I am confused is the 240 a rear wheel drive car?

Crmzendrgone · 10-01-2009, 10:13 AM

I agree about the gearing. But the demension of the trans would make me think not. I would think the output shafts would have different splines and a tail shaft???

lukasmcdukas · 10-02-2009, 09:40 AM

yes 240s are rear drive

Crmzendrgone · 10-02-2009, 10:35 AM

^^^Oh. I still am thinking there is a design difference I can see imports making car trans the same as truck trans like us AMERICANS. at least back in the day.

swap in a 5 speed manual from a 240. guaranteed to work and your little pickup will be a land rocket. you could even turn it into a drift machine.

Yuck !!! an Auto trans with a 4 Popper??? I'm with lukas, if you can do a conversion to a 5 speed do it. Big difference in getting what little power you have to the ground.
