ACTION REQUIRED

Show/hide table

Follow appropriate removal instructions for each model to remove the torque converter from the vehicle. Follow the appropriate disassembly instructions to access the 3P2574 Bearing in the torque converter.
Inspect the bearing looking for the two alpha-character date code (see attached illustration). If the bearing code is "AP", it should be removed and replaced with a new 3P2574 Bearing and 3P2573 Race. If the bearing code is other than "AP", the torque converter can be reassembled without replacing the bearing.
