the 3n71 and 4n71 are a very similar tranny, the OD in the 4n71 is electrically operated.
you should be able to swap the bellhousing over.

i have a mate in auckland with a manualised 4n71 valvebody that he would sell if i asked him.
let me know if your interested

Got curious punched auto R30 skyline into tardme and this popped up at the top of the list
http://www.trademe.co.nz/motors/car-par ... 999249.htm" onclick="window.open(this.href);return false;

This guy is wrecking a L20et AUTO R30, could be a go for a 4 speed L series auto if keen to go that way
Can help out with shipping if he isnt keen to ship up northward. I'm off work till the 16th so no big deal for me too do a little running around. Though I would want a small fee naturally. Shout me a pint if we ever catch up again haha.

hi you can fit a 4n71b in place of a 3n71b.mount and driveshaft are different if you get a non power shift one,it just needs a kickdown switch power down to rear solinoid and over drive switch to power up o/d and lockup 1st solinoid.ratios are all the same for 1st 2nd 3rd as three speed,over drive is diferent.the diesel ratio is the same just rear diff is changed tur suit car,power shift ones need ecu to work.

I have a z31 Auto Trans and converter sitting at my old mans shed, i think its the 4NZ1B it has some writing on it it like it had been serviced or rebuild at some point.

Its all yours if you want to come and take it away somehow from Chch/Rangiora area
