Jeep Wrangler NSG370 transmission shifting problems. Shift fork and synchros.

- If your Jeep doesn't shift correctly, take a look at this video. The synchros aren't big enough to match the speed of the gears before they engage.
Sometimes I can barely get the transmission into first, have to double clutch for second, and reverse can be hit or miss if it's going to be easy to get into. I know the shift fork assembly ain't cheap, about 500 bucks just for the fork assembly, and the gears are about a hundred dollars each. I think I might try and find a reman transmission.
Amazing video! Thank you so much, mine is shot & now I know why.
Just had my NSG370 rebuilt, its all fine except that every other shift into first grinds the syncro teeth.
Hey man great info. I have that exact problem with first and second on my TJ. What's it costing you to get them replaced? Or are you doing it yourself?
I paid $2,200 and I removed the transmission myself. Rebuilt units are hard to come by and often more expensive. My dealer quoted $5,300, but they're criminals. Since it's out of a Wrangler, and Wranglers don't see junkyards very often, there's just no inventory to rebuild and sell as re-manufactured.
I have a very high felling this is what happens to mineeeee how hard is it gonna be to replace and how expensive 🙃
Your syncro teeth look like I expect them to - and the synchro teeth were large enough to work on my Jeep for 180k miles !!
I have a Jeep Wrangler X 2009 2 door. When ever I let go of my clutch in 1st or 2nd gear it kind of shakes a little. But it’s only in those two gears. It just recently started happening and it has 77k miles.
changed the oil recently ?
Yup. Sometimes I have issues going into reverse from neutral but its easier if I go from first to reverse.
It sounds like I got lucky. My nsg370 in my 05 tj x just now got stuck in 6th gear. 330,000 miles on her and still on original everything minus a few fluid changes.
Who inspected your transmission? What model was your transmission in?
My transmission Jeep Wrangler rubicon 2014 auto m speed meter is in 0 and my transmission doesn’t wanna shift . Jeep was involved in an accident and after I put all together I found this problem. Can u help pls ? Thanks
That is a totally different transmission and engine then in this Jeep. Sorry.
I have 05 tj 6 speed manual 100,000 miles just changed clutch master cylinder slave cylinder ,still having problem going into 3rd gear and popping outta 1st ,whats the $$$$ gonna be rebuild this ,thanks
My 2016 Jeep Wrangler just had mechanical issues.
I was driving home from practice and on the way home this guy reversed out of his driveway and reversed into my lane; I quickly moved my clutch to nuetral and brakes fast (I was going 37mph and braked to 3mph). No pop, no grind nothing.
After that happened I attempted to move to first gear and then second; but I couldn't find the spot to shift it in. I pulled into someone's driveway but I couldn't get it into reverse nor first.
Instead of the gears being all centered it seems like it shifted left; now first and second gear are to the Far Left.
I let my dad take a look at it and he noticed that the clutch turned about 45° counterclockwise. And forcibly turned it into the 0°.
What happened????
My 2008 jk wrangler 3.8 6 speed v6 right hand drive pops out of 1st gear on take off. I'm thinking of buying the improved B&M 45195 Precision Sport Manual Trans Shifter Kit from the US which will cost around $800 Australian and I need to be sure it will suit?
My question is this.
Is the shifter sequence the same for a left hand drive US model as the right hand drive export model?
The shifter sequence on my right hand drive jk is forward far left from driver for 1st gear and back far right toward the driver for 6th & reverse.
Hope you understand what I'm saying.
great info! I'm debating rebuilding mine. What are your plans not that the gears are ground down?
+Brandon Lyons I had it rebuilt. It was $2,200. I couldn't find a rebuilt unit for anywhere close to that price. A1 Transmission here in Denver did it, and they did a great job.
+Charles Bloyer didn't trust the rebuilt transmissions on ebay? They sell for $1600. I was going to go that route but if I do it myself I'll save money and end up with a bunch of new tools. Now that I watch your video I'll need to crack mine open before I know if it a real option for me.
Brandon Lyons not worth rebuild I did once now 60000 mls later out again
My jeep will not move. I can push clutch in and will go in every gear but as I release the clutch every gear grinds. Any ideas?
Hey man thanks for the video. I'm having issues with my 06 NSG 370 at about 65K. My question is what if anything did the rebuild do to correct those broken wear items?
Joseph Calabrese They replaced all if the worn parts. It's good as new.
Charles Bloyer don't they upgrade those bushings? I'm pretty sure they was a tech bulletin on this issue. it's the only manual trans offered in a Wrangler to ever make the worst 10 transmission list.
I heard there is an upgraded version in titanium. Wondering what the part numbers are. If anyone knows, post them please
okay here's a question I'm really hoping you have an answer to. I just dropped my transmission. when I took off my flywheel I notice that it feels like a two-piece unit and the actual friction piece where the pressure plate bolts to seems to spin separately from the geared part. is this something you noticed?
+Brandon Lyons Hmmm, not quite sure what you're saying. Perhaps you can make a video and share it with me? You can do private vids.
Second grinds and first which pops out for me at 50k on a15 jku
hi charles i got a jeep jk 2012 and it look a got the same probleme, tel me rebuilt yous transmission and how much cost to you for the trans and tel me why is so weak and how can i help the next trans... thank you

Curious for my own knowledge - was this covered under the powertrain warranty?
0REDSOX7 Didn't have it, not sure.
My reverse in my nsg370 has started acting up. When putting it in reverse, I have to pull as hard as I can to get the gears to engage. Once I can get it engaged, its fine and will not pop out unintentionally. Unfortunately, its been getting harder and harder the last few weeks. Ive been told it's a bent shift fork? What are your thoughts?
Cody Buscher mine does the same thing once in a while..what i do is I put it in reverse to where it doesn't want to go anymore without any force then very very slowly release the clutch to the point it just barely grabs and with a tiny bit of pressure on the shifter it should slide into place
Jon G I recently figured that technique out lol
Hey guys i know this is an old comment I'm replying on but I'm having the exact same issue. It goes into reverse if I pull back on the stick while letting off the clutch but I'm worried about my tranny and this seems like a temporary solution. Did you have to have it rebuilt? Or is it just the plastic housing shown in this video causing stiffness in the shifting fork? Please reply lol
@@adamgerald849 Mine got to the point where I could no longer get it into reverse. No matter how hard I pulled or smacked the shifter into reverse, it just wouldn’t grab. I ended swapping transmissions and never tore the old one apart. I can tell you it was definitely caused by slamming gears like I was in a race car and I found reverse instead of 6th gear on the interstate once..... lol.
Hi ! What about mine.. Soon as it got hot..1hr drive.... I cant put back in 1st when stop on lights...cant put it back 1st if depresse the clutch.. But able to down shift to 1st... As long i dont stop and depresse the clutch. ?? What the fuck ?
Hey Charles I know every shop is different but how much did they charge you to get that fixed?
Vladimir Gomez for a full transmission rebuild your looking at $1800 to $3000.
People do not understand why their synchromesh is destroyed. It is simple. If you refuse to rev match, the synchros will wear prematurely. Most transmissions are "progressive" types, which require that you wait quite long to complete your second gear shift. And then as you go up each gear you shift faster. I get honked at when starting off at lights because I wait for 2nd gear. Rev match into second (long wait) and a shorter wait as you go up the gears. Your transmission will last the life of the car as does mine. I have never owned an automatic, and I have never had a transmission failure. I am a 43 year veteran long haul driver, so I have a bit of an advantage on most green drivers. And by the way, the reason that reverse gear synchro are destroyed, is because you were ramming it too hard. Gentle guys! Stop ramming those poor transmissions, and they'll last the life of your car as do mine. Glad to help!
Doug Stern that’s funny, I have noticed the rpms needing to come down before this transmission goes into 2nd easily. I am a 19 year truck driver and that makes since to me. I will probably have to rebuild my transmission because I didn’t get the Jeep until it had 90,000 miles on it when I got it.
Yeah spot on what you said and also change the oil!! they only hold like 2 quarts ! so change it every 20,000miles dont like it, get a prius or an Auto
Bingo!!!
How much were parts alone no labour
Man, this was so long ago, I have no clue. Sorry.
I have a 1995 wrangler and when shifting into 2nd gear no matter how far you push the clutch in it grinds could that have to do with the gears being worn down like that?
probably late to answer your question, but it would have to do with the syncronizers. does it only do that in second gear?
Yup that is synchros. See my first long post for the solution...next time.
Can I do anything to stop the destruction? It doesn't want to go into 3rd gear. thanks
Synchro issue guys. See my first post.
NV3500 in my Jeep liberty is annoyingly sticky. do you have any idea why?
Rahul Jones What do you mean by sticky?
Drove my 95 wrangler one day and it drove fine and the next started it up and will not go into gear at all what's the problem
At first glance I thought I was looking at a Fiat trans until I read the description
These are mercedes made arent they
Hi Charles Bloyer!
LIKE from Russia!
On my Jeep Cherokee KJ had the same problem NSG370. Here the link jeep4x4club.ru/forums/topic/30161-problemi-s-6mkpp/page-2#entry1319449, as I have repaired. Good luck!
Another reason you dont get a manual for off-roading.
Actually this is exactly why you get a manual for off-roading. Manual transmissions act up, they don't break down like automatics (never mind the fire hazard.) Never take an automatic off road so far that a flat bed tow truck can't reach you.
bad design
