The seal where the wires go into the transmission leaked. It cost me $1000 because the exhaust has to be removed to access it.
Not true.
It cost me a total of $12.95 to replace the control wire fitting.
I jacked the car up on the passenger side, supported with jack stands and had the job done in about 10 minutes with very little fluid loss.
Didn't have to touch the exhaust at all.
Hate to say it, but someone saw you coming.
