Pardon my piggy backing on this thread but it is somewhat related. I also have a 94 855...with about 168,000 miles. It is running well, uses about a quart of oil every 1,000 miles and has annoying cruse control issues in warm weather. Current concern though is we're past time to change the ATF again, based on what I've been reading here on the Brickboard. Anyway, here's the question. We have an oil extraction system where I work that uses vacuum to pull the old oil from equipment that cannot be accessed from below. Does anyone see a potential problem with using a suction system versus drain and fill or the Bay-13 method? It seems that it would be better than D&F but simpler that pressurized method. BTW, both the local Volvo shops recommended D&F and are "affraid" of the Bay-13 method. One of those shops did the last change. Also, the Jiffy Lube recommended a complete system flush that doesn't use the transmission pump to drive out the fluid. Anybody have pro or con comments on that? Thanks & Keep Pedalling.
