I just bought a 98k mile '94 G20t knowing it suffers a 5th gear problem. After reading various forums, I realize this "popping out of fifth" is a common ailment to G20's, SE-R's and NX2000 Nissans.

Just what does it take, and how much $$ to fix it? (mine won't even stay in 5th for more than a second or two). Are these transmissions otherwise stout?

Any & all replies are appreciated. -Don

Have you seen this site yet: http://www.se-r-list.org/fifth.gear.phtml ? I did a search on pop out in this forum and found that $1200 looked like the AAMCO price. I don't know if that was the "carry in" price or drive in price.

Isnt it just the synchro gears that cause the pop out ? and all you need is just a rebuild of them ?
Yeah if there asking those kinda prices i would just get a rebuilt tranny and drop it in.

>>>Where did you get the tranny for $500?

I called a local boneyard who had a tranny from a '95 G20t (with 30,000 miles) for $850.

Also, the shop my car is parked at is quoting anywhere from 60% to 100% markup above Infiniti's parts dept. prices for various bits (trans mounts, clutch kit).

If I need to tow my car to another shop, I may do that.

I havent had mine fixed yet ('91 SE-R), but Aamco quoted me around $370 for labor, plus whatever the parts cost. I told them just do do the syncro and anything else related. There is no need to do all the gears. Im guessing parts may come out to be another 3-400 bucks. They shouldnt charge you any more money to put in a cluch (assuming you buy it yourself before you bring it to them) because they are already going to have the tranny off the car. And as far as the mounts go, just do them yourself. I did all my mounts with my cousin in 3.5 hours, its a piece of cake, just time consuming.

this is the deal with the 5th gear pop. The 5th gear snap ring is trash (needs cryoing). It will become compressed and break over time. As this happens the 5th gear synchronizer hub (which is pressed on) becomes loose and this whole assembly begins to slide back and forth inside of the transmission case, causing the 5th synchro stopper to come in contact with the case. It begins to cut and burn it's way out. Quite nasty. Aluminuim shavings through out the trany. If that's the only thing you want to fix, it's not to bad of a job. The hardest part is getting the transmission in and out. Now once your in there you may wish to do a full rebuild (all of the baulk rings always). the areas to watch for would be "reverse main gear sleeve, 2nd gear bits, all of the bearings, 5th gear and syncro (of course) which also means a new updated input shaft at $142 (wholesale) and any other nasty parts. It's really a good idea to get any parts (never the baulk rings though) that are being replaced cryo treated. A good place to learn more is www.onecryo.com in Orlando FL. There are tons of other bits to watch for and replace during a transmission rebuild. All in all I spent about $1,200 (wholesale) in parts. All the little pins, seals, gears, baulk rings, etc... add up. If you can find a low mileage trany, get it and have the case opened and have BOTH the 5th gear snap ring and stopper "cryoed" (couple bucks) then installed. You could install them if you know how to turn a torque wrench. It's not that hard. Just make sure you have the # ONE helper. "A factory shop manual"!!! Yummmm yummmm. This is the cheapest way to do it right. Any other questions feel free to e-mail.

BTW, Red Line is incredible.

Aamco is the shop I'm at (now). They told me a rebuilt tranny is $2200 + labor, OR I could have THEM do a rebuild with new bearings & synchros ($1420 in parts alone).

They also quoted me another $389 for a new clutch while it's easy to get at (my idea) AND also about $460 (!!!!) for tranny mounts. The labor cost if I have them do all this work is $600, for a grand total of about $2900!!!

I'm willing to work with this shop, but only if they are giving me a reasonable idea of the costs involved.

I'm a bit hesitant to toss the whole tranny because of one problem with fifth gear. The rest of the gears & synchros felt fine when I test drove the car, and it the car didn't appear abused in any sense. -Don
