I have a 1992 740 Volvo station wagon (non-turbo) with 108,000 miles. During regular oil change, the mechanic checked the transmission fluid and recommended flush to clean out dirty fluid.

My problem is this! I do not remember if the transmission fluid has ever been changed. I think atleat once it was changed during the first year that was part of dealer service. It may have been drained just once after that or twice but can not be sure. I have read that if you flush the transmission and dirt is what is providing friction for a worn out clutch pack then you could do more harm by flushing the fluid. Should I be concerned at 108,000 miles? I really do not have any driving problems right now other than sometimes sluggish pickup.

Is it ok to get it flushed in a shop or better in my situation to do it at home using the ipd kit? Should I use 2-3 step Auto Rx or just flush? I know some of the questions have been answered on different posts but still unsure. Any advice will be appreciated. Thanks.
