ZF "D" popout &

[fred89sp]

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.
