Robbo Interested in members thoughts on what might be causing my MY13 D5 XC90 to jerk on acceleration from a stop (for example at traffic lights). It's just started doing this. Having it looked at on Friday but curious as to any ideas or suggestions.
Philia_Bear Engine or trans mount or trans Any clunks or other sounds? How many km Trans ever been flushed? Does it do it if you go into manual mode and select 1st gear?
Robbo 113,000 km. Click sound from front front end when I stop after a take off (been doing that forever, would love to know the cause...) Sometimes it clunks when going into reverse, rarely, but occasionally. Haven't tried manual mode. Unsure about condition of the various mounts or trans servicing.
bigal Damn autos. I hate clunks n bangs. Ironed most of mine out with new mounts and a couple of drain and fills. Hopefully it's simple and low cost for you.
VolvoDeger My question is it a auto thump or are you experiencing a suspension movement?. then we will be able to help out but more info required. Just sorted a gearbox out for a new customer xc60t5 with the MPS6 box which the dealer couldn't fix all the jerking and jumping.
Robbo Thanks for the thoughts and suggestions. I realise I've been very sparse with the description of the problem. The car is just out of extended warranty and so I have left past issues to Volvo to investigate and correct. Hence, don't really know the car that well. It goes into the workshop (not Volvo dealer) tomorrow for investigation. will update on findings.
Vee_Que As the boxes very older the Automatic neutral at a stop feature gets more prominent too. And will bang going back into gear.
Robbo VolvoDeger;125729 wrotewhat area and which workshop I'm located in Regional North East Victoria. And will be now using an independent Mechanic - non Volvo, as nearest is several hours away.
Robbo pastry;125734 wrotesome of it could be.. https://www.ipdusa.com/techtips/10185/axle-ping-yeah-it-s-a-thing Ha! I am almost certain this is the cause of the 'click' noise I've been unable to have corrected. Thank you!
VolvoDeger This click noise is when you go from drive to reverse, you will not get it when slowing to a stop, as the drive line is already loaded in that direction so don't get mislead on this.

Robbo Update: Fault in transmission found and being referred to automatic transmission specialist for diagnosis and repair.
VolvoDeger I have a lot of rebuilds done on them with a slight mod and customers are very happy saying smoother changes than new. Even other independents use this guy as well but also recommend external filter and cooler fitted.
Robbo Update: Rebuild and brand new valve throttle body installed. Will now undertake 12 month transmission service from here on in as a precaution. Cost just under $7k.
