did you disconnect the battery at all during the transmission work..so that the codes will disappear...o well if not disconnect the battery for 10 mins or so maybe less and then reconnect the battery run it around for awhile and see if we get more codes....it could be your crankshaft position sensor, did you put a new fuel filter on it...are your o2 sensors still good..im just trying to narrow somethings out here maybe someone with more exp. could help...im just learning but those could be one of your problems to

Erase the stored codes and see if it returns. You can do this by disconnecting the battery for a while or you can go to the local parts store and have them erase the code with the scanner.

It's best to use an OBDI scanner to clear the codes. Disconnecting the battery clears *ALL* the information stored in the KAM, including the "learned" information stored in the adaptive-strategy tables (eg. info used to control engine idle).
