. . .but I friggin' HATE the NSG370. This is not a rant. Here's what I hate about the setup:

- Absolutely NO feedback in the clutch
- Grinds going into reverse. . .even when I select a forward gear first
- WEAK starts. . .and even after all the programming, etc., still stalls
- Changed the fluid to Royal Purple. . .still shifts like dogsh*t

I've been driving manual for over 30 years, and I have N-E-V-E-R ground gears like I do with this awful contraption. For the record, I've driven old CJ's, panel trucks, pickup trucks and one Dodge Weapons carrier with no issues. So this is NOT a "learn how to drive a Jeep/stick" thing.

My XTerra had a beautiful transmission that shifted light and tight. Never came out of gear, never a grind or a rattle. That thing was a hoss.

All I can say is...this is why the Germans lose wars.

The best part is that NOBODY makes an adapter to at least give us a fighting chance to put a decent gearbox in there. I would kill for an Aisen/Warner right about now.

I guess my only option is to put in a small block Chevy. Any suggestions on transmission swaps that MIGHT be possible are welcome. I have called everyone from Novak to Advance Adapters and nobody makes an adapter for this motor.

Like you we've always driven manuals, but not a fan of the Jeep manual. We dumped our '13 manual after 9 months, couldn't take it longer than that. The three JKs since have all been autos and I love 'em!

And I never thought I would say this. . .but I'm headed that way. What a turd.

At least with GM and Chevy, you had CHOICES. I mean, I can do a swap. I have the tools, etc. to do it. But. . .I don't have the opportunity thanks to Chrysler.

I really wish Ford would buy Jeep. I've always hated Chrysler.

I believe there is a recall for those with grinding issues when putting it in reverse. Something about an obstruction holding it out of going all the way into reverse. I ain't sure, ours does not have the issue.
Additionally, better gearing will make it much easier to drive. Reducing the throttle lag also can help, See Pedal Commander or iDrive for that.
Finally, do you have the hill assist or whatever it is called where it holds the brake on as you are taking off (to prevent it from rolling backwards as you are letting out the clutch)? Some turn that system off, but I found better results once I learned how that system works. Avoid being real hard on the brakes when you push in the clutch, as it holds that pedal pressure. If you are hard on the brakes when you push in the clutch it will hold that while you are letting out the clutch. That makes it much more likely that you will stall. Minimum brake pedal pressure, or no brake pedal pressure, while you push in the clutch tends to work better.
Honestly, ours has better gearing and we have no problems with the gearbox. I installed a pedal commander type widget and thought it was much better (before the re-gear). But after the re-gear the widget died so we removed it and found with proper gearing it did not need the widget. I have a new widget, an iDrive, but have not installed it yet. I will get to it someday.
I would like a better motor, but I am OK with the trans.

Everything you say is 100% true. So here's what I've done thus far:

- Replaced the PCM with one from DiabloSport (I've got it set on the performance crawl tune)
- Throttle body spacer (helps take the last bit of lag out of the throttle)
- Cold air intake
- Crawler exhaust
- Changed all fluids to Royal Purple (Synchromesh in the tranny)
- FULLY disabled the hill start assist for sissies
- FULLY disabled the traction control bullsh*t with a kill switch

I'm running 3:73 gears. I'm actually thinking that I MIGHT be willing to spring for a new clutch. I've heard the heavier flywheel on the Centerforce Dual Friction units makes stalling a thing of the past.

What gear ratio did you opt for?

Ours came with 32" tires and 3.73 gears. That was way too tall and stalling was common. First we added the pedal commander style widget. That helped. Now we have bigger tires, 35.5" tires, and 4.88 gears. Much better everywhere. It has better power on hills and when passing, plus it is easier to leave from a stop.
As mentioned, I leave the Hill Start Assist on, I just learned how it works so it doesn't mess me up.
I don't see how a throttle spacer will help with the type of throttle response we are talking about. The throttle response issue is caused by the throttle being Drive By Wire. Something like a pedal commander or iDrive can help, but in my opinion a spacer can't.
Better gearing would likely change your impressions / experience. A different clutch might help, but that seems like way more than it should need. If the clutch was worn out I could see upgrading it. But replacing a perfectly good clutch seems excessive. I would re-gear first.

Oh, and have you had the recall done?

That may be the source of your frustrations right there. The way Ford’s finances are going, it may get bought out by the Chinese one of these days.

My first four JKs were 6-speed. Some were 3.21, others 4.10. While it wasn’t the most “notchy” manual out there, it gave the Jeeps a fun and more “authentic” feel.

Totally understand your frustration. I never know if mine is all the way in reverse or not until it pops out of gear or starts grinding. I will have to check into that recall.

And to think that POS is made in Germany!

Very frustrating, especially given how good the manual tranny is in my BMW...

There is a way to improve things ever so slightly. Put some good synthetic oil in there, like Redline MTL. Makes shifting smoother, especially when cold.

I think I may be one of the lucky ones. Not a great transmission, but none of the problems that some have experienced. Redline MTL improved things.

Maybe try out the B&M Sport Shifter.

I don't mind the transmission.
The gear ratios seem just right...
At first, I had a hard time finding 6th, but it's now second nature.
At first, I had the crunch/grind/pop-outta reverse, but, I seem to have overcome that.
The shifter needs work... maybe someday I'll splurge for the B&M, but, price and full belly skids have put that on the back burner... ok, totally off the stove.

I hate hate hate drive by wire throttle... good god it's unresponsive.

The hydro clutch has no feel, and I long for a cable version.
I've gotten used to all of it tho, and actually enjoy it these days... but, it is also now my only manual vehicle... well, I still have my street strip Mustang with cable dual clutch, cable throttle and Hurst shifter atop an A5 trans... and that is pure bliss... but, that only gets driven a few times a year.
So I've gotten used the the Jeep, and no longer dislike it.
Is it good? No.
But when your reference point is total bliss and rarely experienced, the Jeep is fine.
Oh, 37's and 5.13's... otherwise stock (speedo programmed).

I did a Centerforce clutch when I was swapping transfer cases (and was halfway to the clutch so why not) I'm pretty happy with it. The heavier flywheel does change the feel but not much and in a good way. Still not a tremendous amount of feedback but it's fine. https://www.wranglerforum.com/f202/centerforce-clutch-for-a-3-6-install-1749338.html

With respect to your grinding issue, I would take it in to the dealer to see if they can do anything under warranty. My NSG370 shifts just fine. It's a truck transmission and doesn't shift like a car but it's better than the NV5600 I had in my 2001 Dodge with the Cummins. I never get any grinding unless I blow a shift trying to shift too fast, which is almost never.

With the grinding into reverse, how long do you have the clutch in before trying to go into gear? It may just be that the box is still spinning if you do it too soon. I wait a second or 2 & it is not an issue, but if I go straight in as soon as the clutch is in, I'll get a bit.


I still stall occasionally, & can only dream of 3.73 or 4.1, I have the 3.21 diffs. What I particularly dislike about the box, though, is that reverse is geared higher than 1st is! Who needs to go faster backwards than you do in first forwards!? 60+kph backwards? WHY!?


I will say that once I went to a new slave cylinder & the centerforce clutch & pressure plates, (still original flywheel), it was much lighter, but that is probably due to the slave being very worn & stiff.

The six speed is the same one they’ve used for last 12 years. I had to let go my beloved TJ 2006 with that same manual tranny. So they say. I searched and searched for a manual JK and most were autos. I only found a couple and they were both out of state .

Big drive but I finally got a JK with manual and so glad!!! I can’t even believe it’s the same transmission. It’s smoother, but the other one worked great too . This one has a shorter throw. Once in a great while my old one would grind going onto reverse, can you just Gotta move the vehicle a tad and she slides right in . ; ) I love that about manual. I hate autos. So boring to drive .

Mine is just stock, 3.73, and I like it better than with my rubis (tj) lower gears. 1st was barely useable. OP, Either you don’t like manuals, Or somethings wrong with yours , hopefully under warranty if the latter.

i think its the whole package that makes it shit honestly. the drive by wire throttle along with the vague feeling shifter and no feel clutch make for a crap manual.


i long for the days that i had my 94 f150 5.0L with the 4 speed manual. even with a bad 2nd gear synchro it STILL felt better than the nsg370! it had a proper clutch feel and the throttle was controlled with a cable as it should be. made for a really fun to drive truck, even if completely down on power.
