are they same? are they stronger? found one thinkin bout gettin it or a 97 j30 car.

Cannot say I have heard of it being done before but I would think the interface between the CCU and the transmission would be different because the 3.5 has drive by wire.

electronics are completely different

dont think so 3.5 is a different engine

Good luck getting the j30 transmission to fit.

^^^ yup j30 is rwd

lol i meant i30 ....got one today out the i30 with 155k miles gonna attempt to open it tommorow in install transgo shift kit. tried finding a 5 speed but cant find any in Houston i wanted a swap.

While not exactly what you want to do, my cousin installed a 00 GLE trans into his 02 SE. There was one revolution sensor in the 3.5 trans that the 3.0 trans did not have. He just plugged it in and zip tied it up. Everything is working fine.

ya they looked very familar. jus figured it shifts better n stronger then stock 4th gens. but im gonna install transgo shift kit.

Gosh Travis, I am confused.....

You say you are a "mechanic". You should know the answer to thr questions you ask, right????

So why are you asking a group of people in their thirtys down to teenagers what the best transmission is????

I think I know the answer. The young people on this forum are quite capable and helpful. I have been working on my own cars for forty years now. The information on this website is quite extensive. I am impressed.

God help your customers.......

Should of hit up Aackshun, dont know if spelled right, but lives in Houston or near by and works at NISSAN Unlimited, probably could of found a tranny with less miles for you...

I think the 3.5 4spd auto will fit but you'll need the wiring harness and sensor that I'm not sure are even the same connector wise......physically it should work....I say give it a shot one of these weekends!

Except I'm pretty sure they came with a 5spd auto. Could be wrong though

This.

yea physically the 3.5 trannys looked exactly the same. jus dont remember the sensors are same or not.

and Nissan unlimited is a dealer?

they dont have any i just talked to them..im gonna stick with my i30 tranny and upgrade the valvebody.
