yeah, I was thinking the same thing. The trans shifts fine and all that, I drive it every day. but the lock up is funny, and it is throwing the no lock up code.

The trans was rebuilt about 6 years ago and the rear clutches were toast. The line pressure was way low with a port test prior to tear down and found the converter valve partially ejected due to a broken retainer, its a little sheetmetal piece that holds the valve and spring in and at rebuild I put the upgraded retainer in it which does away with the little sheet metal thingy
