<--- highly confused at the moment.

Ya I hear ya, i was thinking the same. But @1/2 off the trans would be $80 and I only found 1 after 3 yard searches. I guess part of me now feels it might be fun to rebuild one and experience how they work. I think I kinda got excited after seeing the animations and photos on this page http://community.ratsun.net/topic/36317-wtb-trans-parts/ But you are right .I probabally don't need it. Maybe I have reached the point of looking for and excuse to buy it. I mean after all the syncros in my trans are worn in 3rd gear and Its grinded in a few times. Also its so tempting with the engine already pulled on that truck in the yard. Its like a couple bolts and that trans could easily be mine. But I probabally should save the $85. Btw thank you all for all the info.

Can you swap out the differential gear to compensate or do you basically need the whole rear end ?

Sorry , my bad , I been at the yards all day and for some reason 80 was stuck in my head. You are right, its an 83 here is the door plate, engine plate, and trans photo http://i296.photobucket.com/albums/mm178/jonroeb/Mobile%20Uploads/20150522_163834_zpsadw6khez.jpg~original http://i296.photobucket.com/albums/mm178/jonroeb/Mobile%20Uploads/20150522_163818_zpshzjtmthl.jpg~original http://i296.photobucket.com/albums/mm178/jonroeb/Mobile%20Uploads/20150522_163935_zps0aisdo6z.jpg~original and to answer the other statement , i checked the starter, alternator and waterpump and did run it with all disconnected, but little good as the noise already went away yesterday before testing. Even drove it all day without a starter just in case the noise came back.

Found this lonely guy at the wrecking yard today. http://i296.photobucket.com/albums/mm178/jonroeb/20150522_151514_zps99k8q96i.jpg~original http://i296.photobucket.com/albums/mm178/jonroeb/20150522_151548_zpsajbix4qr.jpg~original http://i296.photobucket.com/albums/mm178/jonroeb/20150522_151538_zpsjypkyg9f.jpg~original http://i296.photobucket.com/albums/mm178/jonroeb/20150522_151527_zpsxxsnnwaj.jpg~original http://i296.photobucket.com/albums/mm178/jonroeb/20150522_151635_zpsnig0bgir.jpg~original

What is the difference between my trans number above and the trans from an 80 extended cab trans number fs5w71b he33 ?

OK first no power steering on this truck, but man a conversion to it would be awesome. secondly according to ur theory it is not the trans , cuz that vid was shot in neutral with the clutch both in and out thirdly the noise suddenly disappeared, I removed the starter looking for ..... well anything. even tested the start and bendix with a battery. also removed the belts and checked all pulleys and nothing strange there either. lastly vatozone only carries Valvoline and lucas 80/90w that exceeds gl 4 and gl 5. is this ok ?

you really cant get ur finger to go down. there is a bar in the way. used a zip tie and it goes down about 1\2 inch and hits oil. of course now that I checked it the noise is gone. I seen a post on here about bad carrier bearings and I just don't feel like that's it. no vibration from the stick. trans drives and shifts smooth. strange, very strange.

Thanks. My first car was a blue 79 datsun 310 with round headlights. I miss that ride. I'd like to buy another one some day and I know they appear here from time to time. I don't want the GX with that big rear windows though.

Nice is this an 86 ?

Was the Datsun 310 GX not a popular vehicle? I noticed it doesn't have its own forum.

Step 1 - Complete! Step 2 - I will check the gear oil today, thank you kindly for the oil specs.

Hello everyone, looking for a little help. I got a noise i believe coming from my trans thats not present until above 2500 rpm, and noise will remain high for a bit after the rpm drops back down after a 5 second rev. Pressing clutch in or out doesnt change the sound. A smell is present that smells like a brake pad (aka clutch disc) burning. But the clutch doesnt slip. Perhaps its another similar burning smell , like grease heating up and my nose is lying to me ;-) All of this just started out of the blue when starting it on Sunday. No heavy driving recently either. Truck drives good and shifts good. Here is a vid of the sound. If anyone thinks the trans is going south, please advise as this weekend the yards around me are 50% off. I could use some advise on what trucks to look for in hopes of a match. The firewall plate Reads NG720 reads FS5W71B HF37.
