I have to take my car to the shop today, but what kind of shop do I take it to? I have read the DTC and they were
p0720 = Lock-up clutch does not engage- Possible Causes = Disconnected countershaft speed sensor
connector / Short or open in countershaft speed
sensor wire / Faulty countershaft speed sensor

P0725 = Lockup clutch does not engage blah blah blah....

Little more history....
Anyhow, the car sounds ok accept for a knocking sound that is a little worse or better given the cars 'mood'. The knocking sound appears to be in sync with the flywheel (my little cover is missing on the housing)...I could be noid though I suppose! The knocking is a metal on metal clunk that is slightly affected by the RPM's. The differential was supposedly just replaced...transmission rebuilt >30K/mi ago (by a douche bag....3 times within 50miles).

I can do any kind of diagnostic but I don't feel like dissasembling anything major due to current conditions.
Anyone have a suggestion for my next step in this process....?

BTW- my gauge cluster's D4 light isn't working and hasn't been since the rebuild. I have a feeling that it is burnt out...is this critical to the troubleshooting process?
