NSG370 transmission grenade lol

So after a long 126k km lol transmission is toast. I’ve been reading lots of forums on information about them. The plastic spacers on first and reverse are gone and the plastic part the shifting fork slides in is warn. So I need to replace the entire fork assembly (1400 at cost) and it Chewed out some of the synchro’s and is way too much to have rebuilt. So my question to you guys.... buy a refurbished trans with all the updates for 3500 bucks. Or buy a used trans from a wrecker for 1700? Is the rebuilt one really gunna last longer, in need of some advise

FYI these are Canadian dollars lol

Thanks

I say go with the most expensive thing you can find. Because that's almost always the advice you'll find. lol I'm just kidding, I've had a drink or 3 tonight.

I do plan on keeping the Jeep. Would a refurbished one not be built the exact same way? The warranty is only 18 months and I would have to take a loan at 10% to pay for it. Just trying to weight out my options

I’m thinking of getting the used one and putting in a b&m shifter in? Thoughts?

I would get the refurbed one. I think the B&M shifter is too harsh on the syncros.

B&M too harsh on the synchros?
Ridiculous statement for sure.
B&M equals: cleaner shift pattern, no missed gears, easier to shift all around.
Unless you are bang shifting it like a mustang, it is better for the transmission.
Have you even installed or used a B&M shifter on a JK ?

The B&M shifter reduces the stock throw by 35%. Using the same lever, if you shift at the normal JK speed, you're reducing the time the syncro has to match the shaft speed to the gear by 35%. Or flip it the other way, it's like shifting 35% faster using the stock setup.

Obviously, faster shifts equate to increased heat and wear (same work in less time). Whether that wear is significant, is of course difficult to quantify. Knowing how fragile this transmission is, especially with regards to syncros, I don't think my post was ridiculous, but I agree with the rest of your comment.

Short shifter or factory long shifter, you can ruin your trans w/ any of them if you try to move the lever faster than the syncro wants to engage.

In regards to the short throw, I guess it could be easier for a wannabe racer to tear up the transmission.

Key is to not shift faster than the lever wants to move and you won’t add wear or stress to the synchros.

My apologies, for coming across that way, there is a lot of good and bad info on this site.

Lots of people bad mouth the B&M that have never even used it.

In my experience the B&M cleans up the shift pattern and overall improves the feel of the transmission.

I have never heard of a short throw shifter tearing up the synchros. But I can see your point. It could make it easier for the “gear jammer” to do damage.

You really have to treat the 6 speed like a truck transmission. Slow easy shifts.

I drive mine like it is made of glass. Shift slow and easy.
