Fine when cold but when up to temp it will give a jolt when slowing for a junction/roundabout. Seems to be the change from 2 to 1.

Fluid was flushed a couple of thousand miles ago with no improve

Any ideas on what it could be most welcome.

Same symptoms as me (on XC90). Cured with new/repaired linear solenoids in the gearbox.

I did the repair last weekend - see this post for details:

Excellent work, thanks for that.

It seems straightforward enough(ish). I'd be interested to know how much replacement solenoids cost though as it seems easier to just replace. I can't check Ebay at work - do you know off the top of your head?

Also if I went to an auto gearbox specialist with these solenoids in hand and said "change these please" would they know where to start?

And another.... did you carry out the adpation procedure mentioned in the PDF article?

[timh30]

The Rostra replacement solenoids are about £180 + import duty etc.

I don't see why a competent garage wouldn't be able to replace them for you.

No - I don't have Vida to do a full adaption, but there are some instructions on the web for a 'soft' adaption.

FIXED IT


Dead simple really. Traded it in for a 2008 BMW 525d msport Touring with a manual gearbox.

:-)

Grateful to all on this forum, been very useful indeed.

Well Done ,
So how about giving us a quick run down on what you did in the end, so we can all give it a go.

I have been told that hot is better than cold; also I have read that when hot, you should go through all positions for the gears for a couple of seconds each, turn the engine off and then let the car stand for 2 minutes. Others say measure it with the engine running????

It's a basic but important question :-)

Automatic transmission fluid levels are always read with the engine running.

I was being a little obtuse there I suppose.

The car still has gearbox issues. They are no longer my problem however.

LOL,
I re-alised that as soon as I posted (Doh),
But I was hoping I'd got it wrong and you had sorted it without doing it the easy way, lol.
cheers,

I have an error message stating 'Transmission service required' with an accompanying orange engine service light.
The transmission is fine for about 10 or 15 miles then usually reverts to a 'dash' instead of reading 'D'rive, 'N'eutral etc. and then goes into limp mode.If I turn off for a few minutes the transmission will work correctly for another few minutes. A longer stop extends the transmission's correct function. If the software is giving a correct display 'D'rive etc. the trannie is working well, quiet, shifting effortlessly, good kick-down etc.
I took it to a local auto trannie expert who checked the fault codes and said that it is an internal error. (lock-up and service clutch low pressure). It's an 'Aisin Warner model 55-50-SN' converter

However I like this Volvo S60 and will give it another chance, I'm obstinate like that. Having looked through most forums , looked at the likes of 'Howard's Volvo maintenance' and even tried 'Justanswer' (rip off), and talked to the transmission repair guy.

What I don't understand is how the box works perfectly some of the time, today for instance I drove 30 or 40 gentle miles with no problems whatsoever.

I wonder would an ATF change (with recommended fluid) get my pressure back up and I thought I would also fit a new 'B4 servo cover' as a matter of course. Maybe I should fit a recon Torgue converter ?

First things first, have you checked the oil level? If its very low you could have pressure problems

How long have you had the car? Has it done this all the time you've had it or only started recently? If its new to you someone before you might have done an oil change with the wrong oil type, resulting in oil that's too thin when warm resulting in low pressure.

Do you tow anything with the car? Sometimes the transmission service message appears when the gearbox oil temp has been over heated a number of times. Towing heavy things a lot might cause this, and new oil would help.

Have you ever topped up or done anything with the gearbox oil before? What colour is it and does it smell burnt? How many miles has the car done?
