Default Proper ATF for 4L65E

06 GTO ,,,,,,Had my son's 4L65E rebuilt and installed it yesterday for him. I did not think he had an owners' manual for it so did not look for one. Bought and installed Dexron lll today and started car to fill torque converter and have trans dip stick at full mark. Went to put paperwork in his glove compartment and, of course, there's the owners' manual.

O/M specs Dexron VI for transmission. My question is: is the Dexron III ok and if not how can I get the Dexron III out of the torque converter? Does the valve body have to be removed to get this out if it's necessary.

How dumb on my part!!

Thanks in advance, Jerry
