Volvo AW72 transmission
An automatic gearbox built by Aisin of Japan used the Volvo 16-valve B234F 4-cylinder engine found in the 740 GLE. This gearbox is a modified
AW71 with different ratios to leverage the unique power curve characteristics produced by the 16-valve head (when compared to the 8-valve B230F/FT with an AW71 gearbox). Some of the B234F-equipped 740's came with a ZF-made gearbox (designated by a gearshift labeled "P R N D 3 2 1"). The AW72 (gearshift labeled "P R N D 2 1" with a side-mounted overdrive lockout) is widely considered significantly more reliable than the ZF transmission.
