AP is the 4-speed automatic gearbox created by Automotive Products and the BMC for MINI vehicles. The prototype of this famous gearbox was released in 1962. It took
about a decade of engineering and manufacturing efforts before ordinary 2-speed
gearbox turned into the unique 4-speed automatic gearbox.

Technical issues and repair guidelines
This was a great achievement to manufacture a 4-speed automatic gearbox that could be operated like a manual unit. It was one of the first automatic gearboxes with east-west mounting produced for FWD vehicles. Moreover, the construction of this gearbox implies the usage of lubricating oil instead of common ATF. This gearbox was also installed in BMC ADO16 and Austin vehicles. Specialists claim, that the crankcase oil should be changed every 10 thousand kilometers, because the oil condition is very important for this type of gearbox. One of the most common malfunctions in this transmission is related to the F-clutch that may get out of order because of the gearbox construction peculiarities (clutch gets the drive torque after multiplication via the gearbox).
