2012 Hino 268 Transmission

Hi Guys,

The check A/T light came on last week while driving the truck on Friday. We did take the truck in to the dealer and the dealer is advising that it needs a new tranny. The code code that shows up when we connected the Allison Software is P0741. We did clear the code. The truck drives fine for 10-15mins until the message returns. The truck has the Allison transmission.

Thanks for your help

P0741 indicates a slipping torque converter clutch.

Replacing the transmission is a viable repair. You might get lucky with just a torque converter, but without a lot of testing you won't know if the torque converter is at fault, or if the fault is in the transmission.
