My Volvo a V70 T5 2000 model sudddenly developed a whining noise .I was going to check it out before the end of the week but ended up with a ISUZU gearbox problem which i completed yesterday.Anyway the car rumbled and i got a transmission service required with a chk engine light.The car moves very slowly in drive and jerks during selection from park to drive.The oil is red and not discoloured,any info with regards to this will be appreciated.

Regards
Leon

 

It may be the neutral safety switch. I'm old school I forget what Volvo calls it. Just a flying guess.

Do you have any other symptoms? does the car start off in a higher gear or anything like that?

 

Hi
It has a whining noise when you select it into neutral and drives with hard gear changes.The messsage was cleared by a volvo mechanic as it indicated the valve body but still seems to be driving hard .The whining like bees buzzing is quite audible.

 

Sorry whining worse when in drive

 

Can you tell if the whining is coming from inside the transmission, does the RPM of the motor coincide with the whining?, Sorry I have to ask all this but trannys can be very difficult to figure out

 

Yes from inside the tranny and it gets higher with rpm increase.Oil level is redd and at the correct level.

 

Did anyone mention the possibility of the planetary gears?...not really sure if volvo calls em that but the reason I ask is because if the whining coincides with the rpm, then it's some internal part that is rotating, or a possible bad shaft or bearing of the part/parts that are rotating? make sense????

 

It's calledd the PNP switch.

 

Thanks Colt. That was driving me nuts.

 

My pleasure, the nomenclature for these things????? you have to think like your in the military, everything is in abreviations ans sometimes backwards !!!!!!!!!! But I love em!

 

I dont know.Would it help if i drained the oil flushed the box and refilled it with new oil.Does it have a filter and pump etc.I dont know much about these gearboxes .Where could i get a manual for it?
