95 Tranny

[ecdhold]

Anyone know why my 5-speed shifting gets "sticky" Is there something I should lube? It's been like this for the past 2 years, making it hard to shift, especially after it's been driven for over 10 minutes.
Thanks!

mine does the same thing im not sure why but ive put 167,000 mi on it and i race alot so that tranny has been threw hell and its still good and strong so i wouldnt worrie about it "If it anit broke fuck it"
Later

my 93 alty does the same. shop told me that it was a problem with my linkage but as long as it was still workin not to worry bout it

my 95 did the same thing, aparently from what i have been told, it's a problem with the linkage...it sticks every now and then

Anyone know how to get to the linkage to correct this?
Thanks

nah, when mine went, my tranny AND clutch were going, so i just had a rubuilt tranny and an ACT performace clutch put in, cost my about 1200..

linkage isn't servicable, cannot lube it, replace.
super easy self-replace at home part, just need patience and 4 jack stands.
If you get clutch be sure to have flywheel checked out and pay for resurfacing if needed, you'll be glad you did

Anyone know where I can get my hands on some tech articles, like how to replace the linkage?

My transmission used to stick in 5th after it was driven awhile. The pieces that move to couple different gears together as we shift in any transmission are shaped on an angle so that as power is applied it pushes the coupled pieces tighter together. That is so they won't reverse the angle shape as they wear and push the coupling apart under power and slip out of gear. Detent balls and springs are not the only thing that hold a transmission in gear. The Nissan maintenace schedule says change the oil every 30,000 miles or 24 months. Using thinner oil will let the syncros slide easier and grab quicker allowing the transmission to shift faster. Don't use thicker oil than Nissan specs. I recently replaced all the bearings in my transmission. It probably still had the original gear oil in it at 116,000 miles. I use SAE 15-50 Mobile 1 motor oil in it. Costs about the same as stinky gear oil. My transmission does not hang up in 5th gear now. Honda uses SAE 5W-30 motor oil in their transmissions. Many manufactures use thin oil in their transmissions. Chrysler Muscle car manual transmissions use ATF. I believe the linkage is the same on both ends. A bushing with a bolt thru it connected by the tube. If the bushings or pivot points are worn the shifter will be loose when it is in gear. Thick sticky dirty gear oil makes the transmission hang in gear. The problem should be worse in cold weather. Change oil instead of the shift tube.

You're fortunate - my rebuild came with a lot of gear noise from within the tranny - bearings were shot at 70k miles. 115k now, some bearing noise is back, that's the risk with a rebuild. Since the have been using redline fluids, changed only once since the 70k rebuild - not sure why I'm not getting the miles out the manual transmission I would expect. First time around the factory fluids had not been changed.

Shifts smoothly but has bearing noise somewhere when you let out the clutch. Linkage was only replaced because it was sticking and squeaking like crazy and I was tired of the noise!

As a 3rd car, it doesn't see the miles it used to, but I swear the transmission is the only weak link in an otherwise very good car w/o problems of any kind. Wife is on me to get rid of it, but as original owner and no complaints it makes a great car for winter (better than my 350Z or G35 Coupe!) and besides, with suspension mods and a few other low-tech changes, it is a blast to drive on backroads fast ;-)

Very impresive presentation of clean and practicle modifications. I like your style. If I had anything like it, I would hold on to it.

I agree with you. Manual transmissions in Altimas are a weak link. Bearings in the manual trans will wear no matter what and make noise. The bearings are very expensive and you have no way to know what your getting with a rebuild or how many miles are left in a used replacement. Noise when the clutch is released and motor running is from the two main shaft bearings. I am fortunate that I don't have a squeak... Yet. Could you see which pieces were worn or squeaked after you removed them? Looks like the only things that stop an Altima are the distributor and running out of gas.
