I have volvo s80 it shows me transmission serves urgant

You could be more specific with the issue:

• Transmission type (Manual/Automatic)?
• How did this issue appear?
• Does the car change gears normally?

Your car seems to be an automatic transmission model?
So the fault code is "Gear 3 Incorrect Ratio"

This means that you may have:

• Low transmission fluid level or dirty transmission fluid
• Faulty or dirty shift solenoids
• Transmission mechanical problems
• Transmission hydraulic control circuit issue

No. As with any vehicle, maintain clean transmission fluid, and the car will serve you well. However, the 2002 S80 does have a high frequency of instrument cluster failure.

parts tore can say for sure but its usually in pints..4 pints to a quart..so 16 pints is 4 qts most take 6 qts or 24 pints..just to give you an idea..put 2/3rd of it in and start the car fill to level according to the stick.

They are solenoids that go bad. If you replace one, replace all four solenoids. The kit costs about $100 on ebay. It is a difficult job gaining access to the inside of transmission. Pay someone that knows how it's done.

the trans is goning to be expensive. 1999 and 2000 are the worst years of s80. PLAGUED with electrical and software problems. yes sure most of the problems have a fix now. but not free

Try removing the battery for half an hour or so and then reconnecting (check you have all your radio codes etc before you do this).

All I know is that volvo does not replace shift solenoids anymore. I dont even think you can find that part. I used to work for volvo and the manufacturer would have us just replace the transmission. You can get a factory instruction manual from volvo. Its called a first edition manual. They are not cheap. It might be a good idea to bring to the dealer, just find get a second opinion.

listen to volvo the one you may get aftermarket might cost you more in the end than just getting the volvo one they are simple but very picky cars they dont respond well to aftermarket parts

i got an volvo s80 and today i got the message on dashbord like this TRANSMISION REQUAIRED SERVICE what its that ?any one can help ?

It is not unheard of for the transmission cooler to fail in such a manner that you end up with coolant in your transmission, and transmission fluid in your radiator.

If this just happened recently you can usually just replace the radiator and flush the transmission as you said and be fine.

However water/coolant is extremely harmful to the automatic transmission, it can cause the internal clutches to break down inside it and fail.

If it were my vehicle I would take my chances and get a new radiator installed and flush both the cooling system and the transmission, this will more than likely cure your problem.
