My transmission started leaking from where the axle pops into the tranny (driver's side). I checked it out closely and thought it may be the seal that is in the tranny so I replaced it...I had a tough time with the installation of it, when I tested it out, it was still leaking. I thought maybe I installed it wrong...so I redid it with a brand new seal. Still leaking. I took the axle to a local transmission shop for a visual inspection...they said the axle is okay. I am puzzled on why it is still leaking. Anyone with any info, please help.

Thanx

 

ususally, it's the drive shaft seal. you've done the replacement many times, maybe it isn't. however, when you are replacing that seal, you need to make well sure that nothing, and i mean nothing, not even a spec of dust gets in the way where the drive shaft would insert into it. also, i would recommend prior to installing the new seal, use a can of aerosol brake cleaner and spray the heck out of that ring fitment to ensure the cleanest surfaces. you may find your defect where it is leaking that way. other than that, no reason for leak except your drive shaft is bad. tranny shop looked at it; i didn't, so i say it can still be faulty...

 

ohh yea....and my reverse doesn't work..lol
When I try to shift it to R, it just pops into 4 wtf?

 

bump 10 char

 

Search the net for problems associated with this tranny. The bearing preload was off from the factory, causing premature bearing failure, which caused leakage. Mine did that at 110K miles, bone dry, kaboom. Found info on net but cant remember where as it was about 6 months ago.

My 5 speed transmission is leaking near the CV inputs

--------------------------------------------------------------------------------

There seems to be a problem with the 5 speed 4 gen. Maxima's transmissions. Namely 95-97ish models with around 60,000 miles on them. A common problem is the differential bearings have failed. Seems to be that Nissan/whoever built the tranny did not bother to properly shim the preload of the differential bearings. Tell tale signs of differential bearing failure include:

-leaking seals
-metal shavings in transmission fluid
-play in the CV axle where it enters the transmission
-grinding/whining noises when the car is in motion

You may also have the problem and not show any signs of it. My car did not show any of the above signs, until I opened my transmission for a different project and discovered it. Simply changing the seals is not the answer either, as they will just get stretched again.

The repair bill of this item is very expensive due to labor. Probabaly $800 to well over $1000 for labor charges, to change the $35 bearing(s). The transmission must be taken off the car and disassembled to service. If having somebody else do the service, BE SURE THEY PROPERLY SHIM THE NEW BEARINGS OR ELSE THE PROBLEM WILL CROP UP AGAIN!!! Many times the repair shop will just say "screw it" and not shim the new bearings. This is a great way to put a patch on the wound that will just break again.

"Can I do it myself?" Sure. Just prepared to remove and diassemble the transmission from the car. You will also need a precision dial gauge indicator to properly shim the bearings, a factory service manual, and you will need probably a week to wait for parts to come in. Definately not a job for the amature mechanic.

There is nothing you can do short of crossing your fingers to prevent this from happening, it is a manufacturing defect. Hopefully you will catch it before the 60,000 mile powertrain warranty is up.
