The bulletin lets service centres know how to handle the truck’s 8-speed auto, if it exhibits certain wonky shifting behaviours
- Certain 8-speed automatic transmissions in Toyota’s new ’24 Tacoma may be acting sorta wonky
- But there’s good news, too: Toyota does have a fix in the hopper, one it’s sent out to techs in a TSB
- The technical service bulletin notes the optional 6-speed manual is not affected by this issue
For those unfamiliar, a TSB is one step shy of a recall, acting as information or a set of instructions for repair centres (usually dealers, but not always exclusively) about some known problem with a vehicle. Unlike a recall, TSBs are not a mandatory fix, but ironically they usually enter the public eye because owners have been clamouring for a solution to a particular problem.
The issue seems to stem from wonky actuators in the transmission, resulting in all kinds of error codes and undesired behaviour. The malfunction indicator light is likely to illuminate in trucks with this problem, accompanied by shifting issues. According to the TSB, “the automatic transmission assembly and the torque converter need to be replaced to address this condition.” That’s no small job, though it is limited to the eight-speed automatic and does not encompass the six-speed manual ‘box — however, it also doesn’t discriminate between the hybrid and gasser powertrains.
