2009 camry, 4 cyl auto with the U250E trans, will an ECU cause the two codes to appear? The car has 208,000 miles. We believe that the car was maintained well by the previous owner. Do you think I should try an ecu from online and will any used ecu for the 2009 camry work? Alot of people say 90% of the time it's the ecu causing Trans codes. P0793 intermediate shaft speed sensor "A" circuit no signal its also giving off a LEFT rear abs sensor code c1333. P0776 also present on obd2. Thanks Scotty! We love the youtube channel n are sub'd

What makes you believe this? Do you have maintenance records? Has the transmission fluid been changed regularly?

No, don't throw parts at the problem, diagnose it or have it diagnosed by a professional. Note that a faulty ECU/PCM is at the bottom of the list of potential causes for those codes:
