kevins750 Posted October 5, 2013 Report Share Posted October 5, 2013 Got some rust issue's and a slipping automatic tranny but I will tackle'em soon.. Engine ran pretty good bringing it home. 1 Quote Link to comment
datzenmike Posted October 5, 2013 Report Share Posted October 5, 2013 Auto's by nature seem to slip. Check the fluid, full and red? It's fine then. In due time loose the rear bumper, side mirrors and lower it a couple of inches all round. Lots of info and help here for doing that here. Looks good now.. it'll look even better later.

kevins750 Posted October 6, 2013 Author Report Share Posted October 6, 2013 Hello to all, I am new around here...My plans for the truck are just to get the tranny properly working and address the floorboard issue and then run it.....I am new to Datsun's but have been around econoline's, jeep's and motorcycle's most of my life....Got quite abit of work to do, and this may not have a great candidate but not much to choose from around here....Anyway I will be around asking questions and hopefully helping out eventually....Kevin Quote Link to comment
Koin Posted October 6, 2013 Report Share Posted October 6, 2013 I think you coulda done a lot worse man. I've seen some pretty rusty piles of junk turn into gems over time. Just keep at it and have fun :-) Quote Link to comment
KlassicMotion Posted October 7, 2013 Report Share Posted October 7, 2013 I like the beauty rings on your wheels! You don't see those too often. Quote Link to comment
]2eDeYe Posted October 7, 2013 Report Share Posted October 7, 2013 That floor isn't to bad really, the body mount area seems to be solid so you will only have to replace the pan area. Welcome aboard :D Quote Link to comment
kevins750 Posted October 7, 2013 Author Report Share Posted October 7, 2013 Is there a master list of what tranny's will swap from truck to truck and year to year? If not I am looking at a 3spd auto from a 720 into a 74 620....don't know what year truck the 720 tranny came out of, it's on CL near me.... Quote Link to comment
]2eDeYe Posted October 7, 2013 Report Share Posted October 7, 2013 You will want one that came from behind the L20. The transmission from behind the NAPZ motor will bolt up to the motor but has a different lean and will not bolt up to the transmission cross member. 1980 was the only year that the 720 came with the L series motor.

Eagle_Adam Posted October 7, 2013 Report Share Posted October 7, 2013 1980 should work for your 620 Quote Link to comment
kevins750 Posted October 7, 2013 Author Report Share Posted October 7, 2013 I called and he said it came off a Z 2.2 motor..so maybe it won't work Quote Link to comment
Eagle_Adam Posted October 7, 2013 Report Share Posted October 7, 2013 wont "bolt up" the same, may be usable but i wouldn't suggest it Quote Link to comment
Eric Garside Posted October 7, 2013 Report Share Posted October 7, 2013 If he already has an automatic tranny from a 620, coulnt he do a bell housing swap? Basically the opposite of what was done on Redeyes green truck? Quote Link to comment
datzenmike Posted October 8, 2013 Report Share Posted October 8, 2013 The bells on the 3N71B are removable. If you have a '74 automatic take the bell of it and swap onto the 720 auto. Now having said that,.... there was a change made to the '81-'82 automatics. Not sure of the exact date and the owner probably doesn't know the year anyway. What Nissan did was introduce a locking torque converter. It is fully automatic and over a certain speed it locks the torque converter. It is not a 4th gear but it does drop the revs slightly. The torque converter and the flex plate are much different than the '74 620s. Now the one in the picture may not have this in which case this is a simple bell housing swap. If it does have the torque converter lock out then you will need the 720 flex plate and converter that comes with it. Really hard to tell from this picture. The flex plate looks pretty flat to me. Regular 3N71B left and locking converter type right. Transmission side shown. EDIT Looks like a simple bell swap. I checked into this and the locking TC was introduced 11 / '82 when the Z24 motor started being used. 1 Quote Link to comment
kevins750 Posted October 8, 2013 Author Report Share Posted October 8, 2013 Sounds good, will I need to do any other swapping from the 620 auto to the 720? Are the tailpieces the same length? Quote Link to comment

flatcat19 Posted October 20, 2013 Report Share Posted October 20, 2013 Wow. That was a vague post. Totally deserving of it's own thread. Do you have a build thread? Start one and have all your project related questions there. Will make it much easier for you to reference later. Quote Link to comment
