This bulletin applies to 2016-2017 Honda Pilot vehicles. Because of a transmission case flaw, the inside of the torque converter bracket hole in some 9-speed automatic transmissions is porous enough to allow ATF to leak from the hole. This flaw was found by the transmission factory during production.

As a temporary fix, the factory installed a sealing bolt in that hole and it’s proven effective. That casting issue has since been resolved, and later castings don’t have the issue. So, the sealing bolt is no longer needed.

If you order a reman A/T and its serial number is higher than what’s listed in the accompanying chart, don’t worry about a missing sealing bolt.

MODEL ……………… DRIVE TYPE …………………. SERIAL NUMBER

Early reman transmissions required a sealing bolt at the lower bracket bolt hole due to casting porosity.
