Hi all,
First post here. I drive a 2007 Jazz petrol CVT 1.4 (mileage 170k). Issue 1: I have been experiencing occasional jump (at around 2000 rpm) when trying to accelerate. When it happens, it will continue to happen 4-5 times. Issue 2: recently I can hear a whining noise when I change gear from to D or R. At N or P the engine is nice and quite. the noise starts when the gear is moved to D/R. Hard to describe the noise but seems like coming from something turning. When I slow down the fast 'whish-whoosh' sound slower. Don't know how to describe it. Took to my trusted garage and they mentioned to take it to a auto transmission specialist as they don't work with autos. Called an auto specialist garage and described as above. Garage told me the CVT had to be changed with a quote of 2600 + vat. The car's value is at best mid 500 - so I need to understand what to do. Some online search suggest transmission fluid flush (last one happened in 2018). Another suggestion is to use Xado 120 after fluid change. Another suggestion is driveshaft change. I am having difficulty finding a garage. I don't know if the two problems are linked. Really appreciate your help.
