Namely, Volvo started receiving reports of failed gearboxes and transmission issues on cars that didn’t even have 50,000 miles on them. Some customization is simply necessaryīranded Aisin AW55-50/51SN, the new Volvo gearbox offered everything this manufacturer had hoped for, at least for a while. This was nothing unusual as pairing a gearbox to different engines means different power delivery profiles. Volvo then took the gearbox and applied certain changes to the design. The project was called AF33, and Aisin delivered, as always. That being said, Aisin will allow individual brands to come in, make certain changes to the design, and slap their own designation to the end product.Īround the beginning of the 2000s, Volvo and many other manufacturers came together to design a new generation of automatic gearboxes that was meant to support future platforms. Rarely do they make a box that is specific to a single make and model. The majority of gearboxes Aisin designs are used across a wide range of vehicle makes and models. However, accidents happen even to the best in the business.

Most car brands have given up on this and left the task to specialized companies such as Aisin. Manufacturing a reliable automatic gearbox is complicated by itself, but designing one can be a total nightmare.
If there are no other indicators by this stage, prepare yourself for a likely valve body replacement.Despite all the black magic trickery that goes on inside an average internal combustion engine, automatic transmission still holds the title of the most complicated piece of automotive tech.

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
