The 6-speed automatic transmission AB60F (-Е – for rear drive) or AS68RC for Dodge RAM of the class extra heavy duty, Aisin name TB-68LS. This transmission was produced by Aisin Co since October of 2007 and paired with the engine V8 (5.7 liters) for 4WD SUVs such as Land Cruiser, Tundra, Sequoia, Lexus LX570.
This reliable 6-speed transmission with "invincible" design tested on rear-driven predecessors А760-960 and on 8-speed АА80Е released the year before (2006). The main competitive product of this transmission is ZF6HP32.

Technical issues and repair guidelines
Electrical components in this transmission is extremely sensitive to the transmission fluid status. The oil change requires specific knowledge and experience.
During the overhaul the following parts are ordered for reassembly:the kit of gaskets and seals as well as kit of frictions.Friction components in this transmission are not complex and serve reliably till the end of the transmission resource. Frictions are usually changed as a result of operation with worn-out rings, bushings and sealing. First of all the, clutch drum Forward (С1 gears 1-2-3-4) gets burnt. All overhauls of the AB60F unit still involve the torque converter repair with replacement of the lockup clutch, replacement of burnt clutch, replacement of the filter and full spare parts kit: seals and gaskets made of rubber and paper.
The valve body design is similar to the valve body of the А960Е transmission and it should be expected that typical problems with electrical components may be the same (after the mileage higher than 200 thousand kilometers without timely change of the fluid and filter replacement) wear-out of channels of linear pressure solenoids. Aisin 6-speed transmissions also have the mode of regulated torque converter lockup slippery, but in contrast to 6НР26-32, here the lock device turns on much later (starting from the 3-rd gear) and have reduced impact on the friction.
Almost all solenoids (in comparison with the valve body in А960) functionally remained unchanged, except for linear solenoids SLU, SLT, SL2 in some modifications. Dirt in ATF damages the valve body and solenoids, therefore cleaning of these components is usually planned as the first stage of the transmission maintenance. During the first years after the transmission release automakers usually modify valve bodies, replace solenoids and change settings of ECM program. Therefore, it is recommended to monitor software changes, which may solve some problems in shifting.Mud accumulation in the valve body and solenoids as well as wear-out of rings lead to lower pressure in the Forward drum that results in premature burning of frictions with steel disks (Forward-C1) and corresponding Forward pistons.
