I recently started to get an error code 67 on my SC400 1992. My O/D light only seems to start flashing after I've driven for a while and shut off the car for a few minutes then restart it. It seems to happen when it shifts from 2nd to 3rd gear.

The 67 code seems to indicate O/D direct clutch speed sensor. Has anybody had any experience with this? Is the clutch speed sensor one of the ones located on the back of the tranny?

Please help.
