Common Mistakes to Avoid
Common Mistakes to Avoid
Over-tightening
Exceeding the specified torque value can stretch or break fasteners, damage threads, or crack components.
Always use a calibrated torque wrench and follow specifications exactly.
Incorrect Torque Sequence
Tightening bolts in the wrong order can cause uneven pressure distribution and potential leaks or damage.
Follow the manufacturer's specified torque sequence pattern.
Dirty Threads
Dirt, rust, or old thread locker can affect torque readings and proper fastener tension.
Clean and inspect all threads before assembly. Use new thread locker if specified.
Reusing TTY Bolts
Torque-to-yield bolts are designed to stretch and must not be reused.
Always replace TTY bolts with new ones. They are single-use only.
Dry vs. Lubricated
Not accounting for whether torque specs are for dry or lubricated fasteners can lead to incorrect tension.
Check if specs are for dry or lubricated threads. Use specified lubricant when required.

Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 Why is it important to use the correct torque specifications for the 10-speed transmission bolts?
Why is it important to use the correct torque specifications for the 10-speed transmission bolts?
Using the correct torque specifications is crucial to ensure proper clamping force and prevent damage. Under-torquing can lead to loose bolts, fluid leaks, and eventual component failure. Over-torquing can stretch or break the bolts, damage the transmission housing, and also lead to fluid leaks. For example, overtightening the pan bolts can warp the transmission pan causing leaks, while undertightening them can also lead to leaks as the gasket won't seal correctly.
Q2 What can happen if I reuse the old transmission bolts?
What can happen if I reuse the old transmission bolts?
It's strongly recommended to replace torque-to-yield (TTY) bolts, like those often used on transmission housings and other critical areas of the transmission. Reusing TTY bolts can lead to incorrect clamping force because the bolt is already stretched. Even non-TTY bolts can have wear and fatigue that may lead to problems if reused. A good practice is to always use new bolts with the correct torque to ensure reliability and prevent problems down the road.
Q3 Where can I find the specific torque specifications for my 2019+ Acura RDX's 10-speed transmission?
Where can I find the specific torque specifications for my 2019+ Acura RDX's 10-speed transmission?
You should refer to the official Acura service manual for your specific model year RDX. While general specifications might be available online, always trust the manufacturer's documentation. These manuals detail not just the numbers, but also if a torque-to-yield sequence is required, the specific thread lubricant to use, or an angle tightening procedure. Using generalized torque specs from an online source instead of your specific manual can lead to component damage and future problems.
Q4 What does 'Nm' and 'ft-lbs' mean, and how do I convert between them?
What does 'Nm' and 'ft-lbs' mean, and how do I convert between them?
'Nm' stands for Newton-meters, and 'ft-lbs' stands for foot-pounds. These are units of torque measurement. Nm is typically used in metric systems, and ft-lbs is an imperial unit. To convert from Nm to ft-lbs, you multiply by 0.7376. Conversely, to go from ft-lbs to Nm, multiply by 1.3558. For instance, a torque spec of 20 Nm is approximately 14.75 ft-lbs (20 Nm * 0.7376 = 14.75 ft-lbs).
