Tranny Broke,,Synchros,, where to get another one?

Well
as the title says, my tranny wont shift into 2, 4, 6 and R
so i went to the mechanic and said the synchronizers went bad, his advice was either getting a rebuilt or a used one,
well i am checking the internet everywhere for another one (ngs370) but i am curious if are they legit, the place i check themost is car-parts.com

does anybody knows where i can get one and for a cheap price, i am in az and all around they have it for 1000 or more,, i think that is too much..

I talked to a couple of transmission places, they told me that would be dealer parts for the NSG370, cost anywhere from 600 or so out of the jeep up to 2k to rebuild depending what was at issue. Let me know if you find parts other than at a dealer. Tools for that are pricy as well I am told by several you need the build stand to do that one.

Hey mike

i called couple of places on CA AZ and NV and they do have used trannies but the cheapest one costs $960 total,,,
it costs from 600 to 2000 to rebuild?
i havent had luck either finding kits to rebuild it,,,,
carparts has some trans though, i find the site kind of dangerous to shop lol

Daveys jeeps sometimes has them, saw a few on craigs.

I talked to two transmission places. Mine was getting crunch into 3rd, fluid was a little dark . They were telling me around minimum of 600 if I brought it in out of the jeep. That was just syncros, goes up for each gear that needs replacing, bearings, etc.

Pondered it myself, talked to a guy on I think colorado4x4.org who had done some at a dealer , he said you need all the special tools or it sucks. That an no one has the parts and I could not find squat for write-ups on it either. The special tools are about 500 bucks themselves, so I gave up for the moment and will change the fluid on it often, running pennzoil syncromesh now and try to put it off. No grinding yet but crunchy more than it should,

Mike you i think you saved my life!
daveys jeeps has one tranny for 850, i will see if the can lower the price on it, or make them a deal of 850 if throw the clutch in there too lol thanks a lot, i will check again on craiglist.

ooooh ok i understand now,, i have been told by a lot of people to buy another one used instead of rebuilding it or repairing the gears,,
mine also grinded in 3rd and reverse at first, but just for no reason four gears went bad :/ i checked the fluid every month since i know getting trannies is a PIA...
what exactly do you mean by crunch,, isnt it the same as grinding lol,,,

Sounds fishy to me. All the synchros don't go bad all at once.

Notice the gears it won't go into are all to the rear in the shift pattern - 2, 4, 6, R.

That would mean all 3 synchro hubs jammed all at once? Not very likely! Reverse doesn't have a synchro - why is that affected too?

I'd suspect shifter problems before jumping to conclusions.
I'd pull the console, look down next to the shift lever for a broken piece of plastic.
Then pull off the shifter - 4 bolts on the top of the tranny - there's a nylon bushing that guides the shift lever held in with a roll pin - in the shifter you just pulled off. That little plastic bushing cracks and splits, then jams, holding the lever from working right.

It's certainly worth the 10 minutes it takes to inspect it.

And - Drain the oil in it, look for pieces and course filings in the drained oil. Let it settle in the pan for a few minutes, then carefully pour it off to see it.
A small amount of steel filings is normal wear and tear. Big chunks of steel - or pieces of brass indicate troubles. If a synhcro breaks, it will have lots of brass!
I'll bet it comes out fairly clean.

Let us know!!!!!!!!!!!!!!!!

Parts - try Anaheim Gear, Anaheim CA, (wholesale supplier of trans parts) - if they don't have them, they can tell you who does. Great people!

Crunch for mine is going into gear, its tight, you can feel the metal on metal but we are not grinding yet. Friend who worked at a dealership said that's the start of the synchros going also the black transmission fluid. Seems to be acting better now that its warming up and their is a few miles on the new fluid. I hear the NSG370 can be a pain in the butt, I'd be surprised to hear its something simple. If it is please share.

Silver - Just draining and refilling is good, but since you already had a problem and dark oil, it's not enough.

When you drained the old oil, what did the sediment look like? ALWAYS look closely at it - diffs, t-case, and engine oil too. That tells you alot about what's going on inside.

Any chunks? Any brass filings?

I'd drain that new oil out - toss it after your close inspection.
When a trans wears tiny steel fragments wear off the gears and everything. It's normal to have some, but when they build up too much they get stuck in the splines and synchros, inhibiting smooth shifting, sometimes even blocking it.

Jack up all 4 wheels. Drain it out, inspect it, toss it, then refill with at least a quart of kerosene.
Start engine, put it in 1st, let out the clutch. Let the engine slosh around the kerosene for about 1 minute.

DO NOT RACE THE ENGINE!
DO NOT DRIVE IT!


Shift into the next gear up - let it slosh for 1 minute.
Do that in all the gears, including reverse.

Shut it off, immediately drain the kerosene out while all the junk is still in suspension.
if it's really dirty, do it again, sometimes you even have to do it a 3rd time. Do it till it comes out fairly clean.

DO NOT RACE THE ENGINE!
DO NOT DRIVE IT!


Refill with the proper lube.

I've "brought back to life" many many so called "broken" transmissions that way.

Hopefully if there's no mechanical damage (you'll see chunks) it'll do the job.

Let us know!

Kerosene in the transmission? Is this a good idea? I am guessing it is being used as a solvent to clean things up.

Can it damage anything?

Newbie to transmission recovery here.

Add to that I did not see any chunks but I did not look very closely either. Will pay much closer attention in the future

Kerosene as not much of a lubricant - WD-40 isn't either - same stuff.
But if you don't race the engine and don't drive it, and just do it temporarily, it helps to dissolve the sludge. That sludge holds the tiny particles of wear in the splines - keeping things from sliding properly. You'd be surperized at how much junk comes out of a "good" transmission, even more out of one that's giving trouble.

The synchros have to be able to slide easily to get into gear. Usual symptoms are hard to shift or popping out of gear. The longer it pack that sludge in the harder it is to get out. Sometimes it's packed in so hard even a stiff brush in a pan of solvent is the only way.

When rebuilding, the majority is just cleaning everything - getting all the junk out of the sliding areas.
Left to long eventually something breaks.

No, it's not a cure for broken parts, but often that's all it takes.

I never kept track, but I'd venture a guess that at least 50% of the "broken" transmissions were just that sludge build up. But we seldom got them when they first started acting up - by the time we got them they'd been pushed until something really did break inside.
Lots of big smiles on customers when their bill is just for a flush and fill when they were expecting a much bigger bill.
It's certainly worth a try!

Always start with the cheap and easy!

And KISS!

i havent been able to find kerosene anywhere, not even walmart carries it in town...
i wanna try that before jumping into conclusions that sychros are bad and getting another tranny.

Also i was going to pull off the shifter as you told me rrich, bit i only took off the plastic and some screws and all of a sudden i can get in to Reverse and 6th,, the only ones that dont go in are 2 and 4th,,,
that is why i am wondering that maybe flushing the tranny by using kerosene might help the transmission if it has something stuck on the sychros..

Do you have a tummy tuck on yours? I read the instructions for mine I am going to install next week, requires the grinding out of the isolator on the shifter. Just wondering since taking cover off is helping you out.

Hardware stores - by the paint thinner and linseed oil.
Wally world, I wouldn't think they'd have it.

Probably even paint stores too.

by a tummy tuck you mean the cover on the bottom of the car, that protects the transmission from rocks and stuff?
if so yes it has one, but i removed it to bleed the cylinder

man
i removed the plastics around the shifter and all its surroundings, so you can see the top of the tranny inside the jeep. thats all i did and started to move through the gears and now its working. its got something stuck on the synchros,,
should i drive it to the lube place to get a transmission flush. or do you think that wont do much good?

The lube place? Usually scammers and incompetants. Do it yourself, it's easy.
If they put flush in, they'll probably race the engine, causing damage.
I won't even let them move my cars, much less get close to them with a wrench.

Rich;

You are so OLD SCHOOL. I bet you are as old as I am or older. Grew up with no money and had to fix your own stuff or WALK didn't you? I swear it seems that before I can suggest you have already common sensed the issue - - 100% in agreement that the problems this lad faces are more in line with a physical obstruction in the shifter rather than a "broken" tranny.

I too have used the old diesel fuel flush on a few gears with good success. Even an old Oliver manual transmission on a shrimp boat responds favorably to getting a good flush job. Diesel will work as good as kerosene for the same purpose.

PS your synchro's will whine on straight diesel or kerosene - dont wo rry about it, they will hush once the lube gets there again.

I have an 06 with the six speed and it dropped the syrcros in fourth gear about three months ago I can't believe to much gunk could build up after 60,000 miles and I had a tranny shop take a look and they told me 1300 for a rebuild and that he was fixing one at the time! And he said that they were garbage and awful to work on. But I've decided to swap it out with the nv1500 5 speed.

Old? Old school? So old there wasn't even schools back then!

I always look for the cheapest and easiest fix - no sense throwing parts at it.
That's how my shops went from very little business when I bought them to super busy very profitable places in short order. (Without any advertising!)

He He - sometimes a rebuilt trans comes without the top - no shifter. Or maybe they take it apart and "rebuild it" (whatever that means). How do you explain to a customer after he gave you $1500 and the problem still exists?

KISS!

lol
well im just finished doing the flush with kerosene. The oil that came out of the tranny was pretty dirty but not dark as other members say.
and some pretty small pieces of metal,,, tomorrow i will open the sifter to check for problems, just in case.
and yeah you guys seem old school, but i think we the newbies have to learn the tricks from you guys. thanks a lot

im done with the flush. oil was dirty and some noticeable chunks of metal. had kind of green dark color though. flushed it twice with kerosene and the second time it came pretty much the way it went in, i was a little worried when moving through the gears since it was shaking a little bit but i think that is normal since the kerosene is not acting as oil should right.

i will let it drain completely for one day so there will be no kerosene at all. so far so good, i will let you know when i open the sifter assembly and after inspecting it. and also after filling the tranny again with fluid. cant wait to try it. you have save me 1000 dollars man!
wish you even more luck with your businesses

good luck but i think you paid a little too much for it.
i have seen those for 400 or 500 and less than 10,000 miles
