Advice wanted
 

I am looking for an XC70 post 07 to replace my 03 V70 manual.

I have been looking for a manual but they are like rocking horse s*** but been put off Auto sealed units due to the problems that affected the P2 00-57 V70/XC70.

I understand they changed the gearbox in the later P3 models just wondered if the later gearbox were as bad or better and what problems to look for.

Don't mind driving either manual or auto but don't want to invest in a car which as a known weakness such as the gearbox or electrics etc.

Suspension, Brakes ect can be modified but major parts like a gearbox are a major expense so want to avoid problems.

None of the P2 or P3 gearboxes are sealed, but the service schedule from Volvo indicates that the ATF does not need changing unless used in 'extreme' conditions like a taxi for example. I've gone from a P2 XC70 to P3 and ATF replacement is one of the things I will be doing shortly just to help the gearbox in good condition. So far at 90,000 miles it is working faultlessly but appropriate preventative maintenance is always wise regardless of what manufacturer may indicate.

The gearbox isn't a weakness as such, rather Volvo's treatment of it in the service schedule as stated. In Saabs the same box doesn't present issues as it's a routine service item.

A thorough pre-purchase check is key, driving for a significant time until thoroughly hot, then a post sale immediate fluid change, unless there is documented evidence of a previous change. You should then be fine.

Yes a transmission fluid change is a good idea, its a bit of a game to do it though, search for the Gibbons method and be prepared for some spillage.

These gearboxes have an oil cooler built in to the main radiator which can split internally leading to coolant escaping into the gearbox. The glycerol attacks the friction linings in the 3 clutches and leads to premature failure. So if you start using coolant act promptly to avoid costly repairs.

It is possible to retro fit an air cooled cooler to avoid this.
