Default Opinion - Should I replace the transmission?

Hi everyone.

I know that my D21 wasn't sold in the US, but I would like to hear you guys opinion anyway.

Currently my 1988 dual cab 4x4 D21 has around 131.000 miles (212.000 Km), and the manual transmission has seen better days. Always grinds a bit when shifting down to 2nd, and sometimes makes a really loud grinding sound when shifting into back when the truck is at a complete stop. Also has some bad bearing (rattling sound that goes away when pressing down the clutch pedal), and recently started making occasional metallic sounds when pressing the pedal, which appear to come from the clutch fork. Had the clutch replaced at around 124.000 miles.

Recently found a guy that is parting out a dual cab D21 Japanese fire truck with only 13.000 miles (21.000), exactly same transmission and truck except for the year (mine is 1988 and his is 1985). He's selling the transmission+transfer case (FS5W71C CA48) for 300 usd, which in here is a great price.

Taking into consideration that I will have to trash the truck when the engine dies (TD23 diesel 2.3L), do you guys think that is worth going through the trouble and expenses of replacing the tranmssion?
Having second thoughts because it would be a rather expensive job, and wouldn't make sense to do it if the engine would die before the new transmission does (if I bought it).

This sounds more like you have a clutch problem. Unless someone beat the holy hell out of that transmission for 130,000 miles, that could be your problem. Nissan manual shift trannies are hard to kill. You might just need a whole new clutch system...everything from the flywheel on back to the clutch disk, the pressure plate, throwout bearing and fork, the slave cylinder, and even your clutch fluid cylinder.

One thing I would do right away is to stop grinding the gears, though. Pull the tranny and check out those parts I mentioned. If that's the problem, replace them and dump the manual gear oil as well and replace that with GL-4 gear oil.

One way to know whether it is in the transmission or the clutch system is to dump the gear oil and see how much metal you get. Most of it should stick to the magnetic bolt. If you get a lot past the bolt, then the gears might have a problem. If not, it is probably a clutch problem.

AT a complete stop, put it in gear, leave your left foot on the floor, take it out of gear, wait, then put it back in to gear. It should go back in w/o any issues.


If the motor is running, and you put it in to reverse/back, you should put the trans in 5th first. Then put it in Reverse. The trans will be spinning, on the inside, and it doesn't stop spinning, immediately, when you step on the clutch.

Replacing the transmission for $300 is a lot better option in my opinion than a new car payment or a used vehicle that you know nothing about.

I agree with the above. 212000km on a diesel... it could probably got to 400,000km no problem. Heck even if were the gas one i'd say replace as the engine could go another 150,000km.


Replace. Or send me the diesel engine.

I'd steer clear of that fire truck. Guy has been posting it everywhere and now he wants to part it out...it stinks.

So, your "GUT" is telling you something... care to share any links you've found? I'd be interested to test my own "GUT".

Probably at least as bad as a Jeep so worse than a cow.

If you have the time and access to a shop press these transmissions aren't particularly difficult to rebuild. Especially if you catch it early, the synchros are probably worn out but otherwise the damage inside will be minimal.

Although it's kind of a wash financially...by the time you buy all the parts/tools and figure in what your time is worth you could just as easily throw in a good used one.

Thank you all guys, think I will end up replacing it.

Rebuilding a transmission here in Japan costs a fortune. Got a few quotations and they all wanted between 2.500-3.000 USD !! So rebuilding one is completely out of question. Same goes for engine overhauls.

Getting a new clutch sets you back to around 1.000 USD too.

Could you send me a link? Would like to check if its the same truck or not.
The fire truck I'm talking about is (was? looks like it was sold) being sold in Japan. Not sure if he posted it anywhere else.
