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 using the correct torque specification so important?
Why is using the correct torque specification so important?
Using the correct torque specification for the 10ssp transmission bolts is crucial for several reasons. Under-torquing can lead to bolts loosening over time due to vibration, potentially causing fluid leaks, damage to the transmission housing, or even complete component failure. Over-torquing can stretch or break bolts, damage threads in the transmission case, or crush gaskets and seals, leading to fluid leaks and requiring costly repairs. Proper torque ensures a secure and reliable connection, maintaining the integrity of the transmission and its components.
Q2 Can I use a general torque chart instead of the specific Acura torque values?
Can I use a general torque chart instead of the specific Acura torque values?
No, you should not rely on a general torque chart for the 10ssp transmission bolts. Acura specifies precise torque values for each bolt based on its size, material, thread pitch, and location within the transmission assembly. General torque charts cannot account for these factors, and using them can result in incorrect tightening, potentially causing the problems associated with both under-torquing and over-torquing.
Q3 Should I replace the bolts when working on the 10ssp transmission?
Should I replace the bolts when working on the 10ssp transmission?
While not always mandatory, it is generally recommended to replace torque-to-yield (TTY) bolts when working on the 10ssp transmission. TTY bolts stretch when torqued to their specification and should not be reused. Some bolts in the 10ssp are not TTY but following Acura's service recommendations is always best practice. Consult the service manual for your specific vehicle and bolt location. Reusing bolts, even non-TTY bolts, that are corroded, damaged, or previously over-torqued can compromise the integrity of the connection.
Q4 What kind of tool is needed to properly torque the transmission bolts?
What kind of tool is needed to properly torque the transmission bolts?
A calibrated torque wrench is essential for achieving the correct torque specification on transmission bolts. Using a non-calibrated wrench, impact wrench, or guesswork is highly discouraged. A torque wrench allows for precise tightening and prevents over-torquing. Digital torque wrenches are even more accurate than analog ones, and are preferred when working on critical powertrain components. Always verify that your torque wrench is properly calibrated and that the calibration is up to date.
Q5 How often should I inspect the transmission bolt torque?
How often should I inspect the transmission bolt torque?
Unless there are specific issues or service procedures, routine inspection of transmission bolt torque is usually not necessary. However, if the transmission has been recently serviced, or if there are any noticeable leaks or noises coming from the area, it is a good idea to inspect the bolts to ensure they are properly tightened. For example, if you notice a small transmission fluid leak, inspecting the surrounding bolt torques is a reasonable next step.
