Price: $1.00
Pros: 4th seems to fill the "gear void" that I missed with my old jeep (98 with ax15), the low first is nice to have for towing and other situations. I like the fact that they're still using them in the new jeeps (mine's an '05).
Cons: I hear that the shift fork fails prematurely, hasn't yet on mine (120k), and mine makes a hell of a hiss... sounds like something's wearing pre-maturely. I've been told "better have that checked out", and I've been told "they all do that"... I guess we'll see
Recommended? Yes

Comments: I worry about the hiss most - when will it get worse and force me into an expensive repair!?. When shifting I detect worn synchros in 2nd and a little bit of wear shifting into 3rd, but that kind of thing is normal for any manual tranny. I bought my jeep ('05) used in 2016. No fork issues thus far. So far so good, I guess, but I baby it.

Price: $2,500.00
Pros: Easy to take out and swap in a better transmission.
Cons: Long shift throw, useless granny gear unless you are pulling a 747, weak shift forks, difficult and expensive to work on, expensive parts, prone to failure
Recommended? No

Comments: Worst transmission I have ever had. Shifting between 1st and 2nd gets hung-up. Reverse gear went out under 100k miles. More expensive to fix than to put in a better transmission. This transmission has no business being in a Jeep. Best thing I ever did for my Jeep was to get rid of this transmission.

Price: $100.00
Pros: super low 1st gear
Cons: ehh..
Recommended? Yes

Comments: I have this in my 05 rubicon. it has only 50,000 miles on it and my 3rd gear synchronizer is going out.. i have to shift it into third slow and after rpms drop some so it doesn't grind...

grannted im not the first owner so i dont know how the person before me drove it. i bought it with 30,000 miles and it worked perfectly fine.. although puting it into reverse was a pain from the start of me owning it... itd seem as though it went into reverse and as soon as i let go of the clutch it would grind and id have to try again. howevor i have heard this problem from a few people here on the forum..

my jeep is lifted 3' on 35's and has done two trips to uwharrie from west palm beach FL (about 900 miles)..just to show a little what its been through

One thing i would do imediatley if your planning on geting one of these is change the fluid to pennzoil synchromesh or PREFERABLY royal purple synchromesh as people have expierience better outcomes with it..

once i changed my stock fluid to pennzoil synchromesh shifting into third gear has become alot easier (probably even easier if i put royal purple in it instead of pennzoil) and reverse really hasnt been an issue with the new fluid..

First gear on this tranny is practically unstopable its so darn low. and as mentioned in a review earlier sixth gear could be a tad pit higher for highway cruising..

otherwise i guess its a pretty good tranny considering the amount of mudding and rockcrawling its been through

Price: $23,000.00
Pros: low first gear
Cons: hate the shifter and pattern
Recommended? No

Comments: Came with my 05 rubi....... IMO the gearing ratios are to close together from 3-5th. hate the shifter feel and pattern and it is louder than my old NV3550 was.

I miss my 3550 in my 02 wouldn't mind trading someone if not for the work involved.
