2002 Volvo AW55-50SN Transmission Disengages While Driving

The disengagement feels like something is not locking up, like the converter. The disengagement happens more in the city when I am starting and stopping, but it still happens on the freeway. For example on the freeway at 70 mph, the car all of a sudden goes into limp mode or the trans disengages. At this moment, the car starts coasting and I step on the gas, but obviously no response – the rpms goes up slightly to sometimes to 2 or 3000 rpms, and then the car kicks back into gear. This disengagement period happens for a minute or it can go on for 5, or 10 miles.

Quick update…spoke with Volvo service and made appt for tomorrow to get it looked at. Based on symptoms I described their guessing Valve Body to the tune of $3800. Does this sound reasonable? Of course they won’t know for sure until they have the car, but I’m having a hard time with that amount in view of what the cars worth. Anybody swap out a VB themselves? I would think I’d still have to have some computer work done afterwards. Thoughts?

Normally, if it gets out of drive but shifts OK I’d take a look at the shifter linkage. When you put in Drive you manually engage a plunger in the valve body so I’d make sure (before starting the spending race) the actual lever on the tranny moves to the correct location, and that’s done by the shifter linkage. One test is to put the shifter in D and try to move the tranny lever by hand (w/out moving the shifter) if you can your linkage is loose.
