Are you a good shade tree mechanic? I can send you the guide for adjusting the linkage and PNP switch but if you can't work on your car it won't do you any good. But you can adjust the PNP switch without the special Volvo tool, just set the parking brake and put the gear selector in the Reverse position and move the PNP switch a few degrees one way or the other till the reverse lights come on steady then snug down the switch bolts and you should be good to go. The hassle is getting to the PNP switch. You have to remove a bunch of stuff mounted above the driver's side over the tranny. It's that flat switch mounted on the shaft where the shift cable connects. There's a good How-To article over at VolvoSpeed Bay 13 on the PNP switch. Look under the repair and maintenance section and transmissions : http://www.volvospeed.com/volvo_performance.php



Good luck.
