Factory manualTaken from a Mazda factory workshop manual, with page citation.
Procedure

Use the vehicle-manual 34 N·m value, corroborated by the 1999–2000 elbow installation note (05–13–27). The owner authorized this same-transmission comparison. Retain the component workshop’s conflicting 25 N·m claim. Lubricate a new O-ring with ATF and orient elbows as illustrated.
