Fellow BlueBird with a Problem with Tranny
Hi Dave,
Craig has an older coach but I believe he's running with the CAT and the Allison MT 643. ('77 I belive was the year the CAT was an option) First, I would check the fluid level. This can be done with the engine running and I believe there are marks on the dipstick for engine idling or shut down. The transmission is controlled by a cable which runs from the shifter to the roadside of the transmission. It runs right by the exhaust on the roadside of the engine where (on my coach) there's a really bad heat shield on the exhaust pipe that doesn't do much good. It's likely the cable is old enough that the heat is causing it to not work very well. What he may find is that if he idles for a while, it might just shift for him as the cable cools. What I would do is stop and get fuel, leave the coach in drive with the brake set, and a co-pilot in the drivers seat just in case, but it's not likely to go anywhere. Once he finds a spot where he can be assured he's got time to fix the cable if it breaks, let it idle a while, then see if it can shift to neutral. If this works, shut down and see what happens after a while of cooling. If this is the problem, I would recommend a better heat shield, and some lubrication for the cable, or perhaps even a new one. If the cable breaks, it is possible to get under the coach and move the shift lever on the transmission manually. It is up high and forward on the roadside. This is certainly a two person job involving a brakeman and jackstands. The old Allisons, to my knowledge, do not have any failsafe features other than automatic shifting for rpm protection regardless of gear selection. Good Luck, Hope this helps, Gary Miller 83 FC 33 Wauwatosa, WI --- In WanderlodgeForum@yahoogroups.com, "Dave Beatty" <beattyd@...> wrote: > > Hello...
