The tightening torque of the automatic transmission housing bolts depends on the specific car model and the type of automatic transmission. Typically it is around:
* 40-60 Nm for most passenger cars
* 70-90 Nm for all-wheel drive vehicles and vehicles with large engines
* 100-120 Nm for commercial vehicles and heavy SUVs
Important:
*Always check your vehicle’s service manual for specific torque values.
* Use a torque wrench to accurately tighten bolts to avoid over-tightening or under-tightening.
*Tighten the bolts one at a time in a specific order to ensure even load distribution.
* Apply a thread sealant (such as Loctite thread sealant) to bolts before tightening them to prevent oil leaks.
