I had asked you about the rapid clutch cycling of my 01 Sport. Took to
the shop today and they indicated iy was a half pound down. So they
flushed and filled system. Drove off the lot and put the AC on and
still rapid clutches. Brought back to shop and we discovered all reads
great in park - it's when in DRIVE that it rapid clutches. I had them
scratchin their heads on this one. So, thaey still have it and I have a
rental. What do you think?

Did it rapid cycle in reverse? I ask because there may be a wiring or
connector problem associated with the motor torquing over. Seen a lot of
problems with the low pressure switch wiring on SuperDuties...

Things that can cause the AC clutch to disengage would include wide open
throttle (I would think that a TPS problem would show up with a running
concern), engine overheat condition, high side switch and low side
switch.... a wiring or connector concern here could give your symptom. On
the bright side, if the problem is consistent in it's appearance, it should
be relatively easy to get to the root cause.

A little more to the story... I have a friend that is a service tech @
a Mitsubishi dealership here.. I took it to him today because Ford
recommended I bring it in next week because they were really booked
today - so this is my fault - I knew I should have waited and let them
diag it. Mitsi was great and thay did all they could - but recommended
that Ford was more appropriate for this since there was a deeper issue
and were unable to use the proper diag that Ford would use.

Thanks Jim for your assistance

Gerry

No prob... hope things work out....
