They say that "good things come to those that wait"....
GMW called yesterday and said the 90 was ready. Stopped by to get the key and talk to Stefan. Seems that the valve body was the culprit (even though it tested OK electrically). Stefan said the car shifts like it should and 1st gear "rips like a mutha".
OMG

This car shifts like "buttah" AND it gets up and goes!
No more waiting to see if first gear can find itself and get moving. Major Props to GMW for customer service and satisfaction.
