ZF "D" popout &
I cannot argue with what you observed but am having difficulty
comprehending how the transmission selector switch could be caused to do that. I have had the switch out of my 89SP and, as I recall, it is strictly a mechanical device with electrical contacts. I do not see how any electrical energy or lack thereof could cause the switch to change selection. If you mean that the switch remained in drive but the transmission went into neutral then you have a wiring problem that I would ask ZF in Chicago for input. Hold off buying a new switch, as I recall they are over $400. Without disputing Fred Hulse's post, I associate blue smoke with oil in the combustion chamber, not a fuel problem. Perhaps sitting allowed some oil to seep past a valve guide. I would price the timing setting job and that would be a factor in deciding whether to observe the smoke for a while before undertaking a fix. White smoke is caused by incomplete combustion, more commonly seen in cold weather. Again I would want to see how persistent this problem was before undertaking work. The crankcase vent vapor you observed is normal. --- In WanderlodgeForum@yahoogroups.com, "williamcharrison" > Hi all, > Just returned from an extended trip with my '90SP36 and (most) all > was satisfactory.
