XC70 TRANS PROBLEM

2003 XC70 135,XXX with a geartronic transmission. When at highway speeds and I accelerate the car hickups or jerks instead of accelerating smoothly. When I put it in manual (geartronic) and downshift it accelerates smoothly without raising the rpms dramaticly. I changed the fluid (3309) last summer and it was on the low end. I topped it off just before I noticed this problem. It is now at the max level (not above) but I don't think this is the problem. Is there a software upgrade that might help? Is there linkage or a sensor that needs replaced?

There may be new software available or you may have the start of an ETM problem, Volvo will cover it, if it is.

I've heard most Automatic transmissions like to be over-filled a little. Don't know if this caused your problem, but I like to stay on the safe side and put in a little extra.

The 2003 XC70 is not covered by the ETM extended warranty. Over-filling is not going to do anything good. Checking for a software upgrade is your only choice if you recently flushed the fluid in regards to the trans. Does the car have a check engine light or trans service light on? Are you sure it is the trans or maybe engine related?
