This has been pissing me off for the longest time. My scanner picks up a *BAD* Quad Driver 4 on my 95 GP 3100. So I been trying to find out what the hell it all means. Finally I got the official service manuals and there aint jack in it. I also have the transaxle book. Nothing. Absolutely nothing. The only quad related info I can find is in the trouble codes. Quad 1 and 2/3 that relates to shifting gears. But there is no other info except the trouble code number. There is no info or diagnostics
