The inner cv joint usually vibrates at 80 km/h .It won't hurt to carry it to a cv joint shop for an inspection before you start interfering with your tranny.Sometimes the cup in the inner cv joint wears and causes too much backlash and hence the vibration and noises .You should also do an inspection on your front wheel bearings for any wear ,play or damage .

Do you have any problems with the tranny engaging?.........if so... then most likely you do have trany problems!

Symptom Condition Solution

Vibration that increases with speed or kicks in at different speeds Excessive play in the inner or outer joints or a bent driveshaft Replace worn shaft assembly

Clunking noise when engaging automatic transmission. Worn inner or outer joints. Replace worn shaft assembly.

Continuous knock at low speed Indicates a worn CV joint Replace worn assembly.

Continuous humming or growling noise. Inadequate lubrication on inner or outer joints (check boots for leaks). May also be worn gears or wheel bearings. Inspect CV joint - replace necessary.

Clunking noise during acceleration or deceleration. Worn inboard joint or differential problem in the transaxle. replace worn shaft assembly or repair transaxle as necessary.

Clicking or popping noise. Worn outer joint. Replace worn shaft assembly.

Shudder while acceleration or deceleration. Worn inner CV joint. Replace worn shaft assembly.

Cyclic vibration. Worn inner tripod CV joint. Replace worn shaft assembly.

replaced CV joints about two months ago at front wheel drive....will check the joints again but the car when in neutral and im rolling down a hill there are no noises, but as soon as i put it in drive and accelerate...noise and vibration....

wanna ask if the CV joints will only make noise when car is engaged in drive and under acceleration or will it make the noise even if it in neutral Question

dis ting is pressure!

hmm and i tell people stay away from m6 ehh

palllie all i can say is do no change ur rims remember cvt works on bands and these bands stretch whn u put bigger rims

look at it this way to pull of on a 17inch rims takes more momentum than pulling of on a 14inch rim weight difference
so stick to 15's and save the tranny and change ur oil on time along with filter

I have an m6 as well,, riding on 17's. Changed the CVT oil and filter. I think the recommended is 40000 km, and i ilso heard that this tranny works with belts.
So far so good,, no probs with it!!!
Looking for a good mechanic to handle any sr20 issues.. though

i have a 1998 nissan primera wagon and im just wondering if anybody else has the same problem, when driving it jerks like your driving a manual car and when in reverse mode change gear drive and its still in reverse mode...slow in changing gears.... if so please let me know what the problem is, i took it to a mechanic and he bloody didn't do sheit, charged me $200 coz he sed it was the engine throttle and still problem not solved... so please im going insane!

proper maintenance and timely maintenance is the key....

40,000 km - 50,000 km is good to change tranny fluid for the m6. i think in japan its 60,000 km but because of our climate 40- 50 is recommended.

sensors have a lifetime in those as well, around 3 yrs..

mines used to work well until.... Rolling Eyes

some idiot crashed into it.

Hello gise ,my name is marcel and i am new( #Newbie

) on this site.
I have a problem with a CVT tranny on a Nissan Serena.
To be honest ,the vehicle came for a starter problem and I fixed that and went for a test drive.And now it is stuck in first gear.I have looked at the speed sensors but they seam to work ok.Does somebody have a wiring diagram on this tranny.
anybody can tell me a maybe what can cause the problem. Question

After I saw that its stuck in 1st gear I also cleaned out the filter and put in new CVT nissan oem ATF oil.still no result. #banghead

Thanks in advance for any help .
#Newbie
