Avoid modern 'super' transmission oils that claim to do everything under the sun. Be sure to use the factory specified Esso/Mobil ATF 3309 (JWS3309 spec) oil for this. If the transmission is unhappy enough about the engine sensors to go limp mode then it will log 'remote' codes in the transmission ECU declaring its disapproval.These boxes are sensitive to fluid condition -gear shifts are much better on new oil- so, if it's done above 80,000 km and on it's original oil then a fluid change is in order. Generic test equipment is usually unable to delve deep enough into the system to be of any use. Ideally factory diagnostic software like DIAGBOX or LEXIA should be utilised to interrogate the ECU for fault codes. If the Sport and or snow-mode lights are flashing this is generally not a good sign, and indicates a major problem. This often doesn't produce fault codes, and tends to be worse when hot They may produce a number of shifting issues but usually don't cause the ecu to veg out or drop into a limp-home mode. But, t hey can have issues with the solenoids and valve bodies, usually when they get older (150,000 km +) which requires the valve body to be replaced (they wear out internally due to the housing being aluminium which causes fluid bypass). The AM6 box is generally considered a good transmission. Specifically the vehicles above equipped with the AM6C Automatic transmission
