High pitched chirp/noise when shifting into N
« on: 03 October 2018, 23:46 »
Has this ever happened to anyone?

Doesn't seem to be my control valve... or engine. I'd almost say it's coming from inside (which I doubt because our cars aren't THAT sophisticated). Servo vac lines?

Any thoughts?

Thanks!

Sorry, I don't have any idea what it could be... torque converter ??? Clutch plate, or clutch bearing??? 
I pulled My clutch bearing apart when I was restoring My car, and filled it with lithium based MOLY grease so it should last forever..  So, it maybe the clutch release bearing that is making the noise due to the grease drying up... and/or the noise when it bearing is in contact with the clutch pressure plate..... if Not fixed it could wear out the clutch plate pressure plate fingers....

Well, I shimmied under the rig and tightened the clamp/band (I replaced the servo bladder 2 yrs ago) around the servo and the chirp has disappeared. Kinda figured that was it.

Great News,
[/size][/color] I have never ever replaced the bladder. I do have spare servos plus the repair kit, but I as said I have never ever replaced one... You must have known that the bladder was leaking.... or an idea... lol[/font]
[/size][/color]what ever, great news, as I had never ever heard of that problem before...[/font]

Hello Lee,

Do have the part numbers for such as the 'Bladder' and the repair kit?
I'd like to try and obtain some just in case ;)


Thanks

I think this where I bought mine:

The hard part is getting the accessibility to the servo AND getting it back on... with the car just on jack stands

Yes, that is the repair kit I have...  Air freight is a killer from the USA to Australia now... 
Freight is usually more than the item being bought...
and when the weight is over 500 grams, the postage can be $40-$60... or more..
or sent to Australia by Australian post - 500 grams costs $65 ...  plus US postage to an address in the USA..
