Powder clutch diagnosis ?

[Arow]

I reckon mine is beginning to go
so i rang up a couple of nissan dealers and an independent gearbox specialist.

First nissan dealer service dept said they'd get a mechanic to test drive it and give a verdict from that.

Second nissan dealer service dept said they would first of all have to eliminate that it wasn't worn brushes by replacing them. If still problematic after that, replace powder clutch.

Gearbox specialist said they would test it by warming the gearbox up first then they would disconnect the brushes to ensure no current was getting through and see if gear lever still stuck when shifting from D to R etc, if it did stick, then the powder clutch is on the way out.

Whose diagnostic method is the best ?

I'd say a gearbox specialist as they have loads of knowledge in one area and nissan need to know a bit about everything.

I'm beginning to think you are right I can't get a consensus from nissan

I've spoken to a third nissan dealer and they said they'd run a diagnostic on it to evaluate the problem but one of the previous dealers said that diagnostics wouldn't show anything unless the dashboard light was coming on - which it isn't.

Whats happening is that after the gearbox is warmed up by driving around town for 10 minutes or so the gearshift sticks when alternating between D & R to park the car in a roadside space.
Whereas if I wait a few seconds before moving the gearstick it goes into R or D more easily.
By sticking I mean there is quite a resistance when entering R or D
I can ignore that and shove it in regardless but that doesn't feel right thing to be doing.

This sticking doesn't occur when the gearbox/powder clutch is cold or has just been driven for a minute or two
nor does it happen after being warmed up if I wait for a bit before moving the stick .

Not sure if many people on here have automatics, i don't so my knowledge is limited, but if the gearbox specialist is reputable i would go with them, dealers are notorious for being rubbish, at least they always were on motorbikes and i can't see it being much different for cars.

Thanks I'll do that then, its a lot further to travel, but the chap I spoke to at the gearbox place sounded far more coherent about cvt's than anyone at Nissan.

Merci, je vais le faire alors, c'est beaucoup plus loin à parcourir, mais le type à qui j'ai parlé au magasin de boîte de vitesses avait l'air beaucoup plus cohérent sur les CVT que n'importe qui chez Nissan.

Bonjour, avez-vous résolu le problème s'il vous plaît ? Je suis dans la même situation avec mon 1.0i 16v CVT 1997. Merci pour votre aide ! Loïc
