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?
Why is it important to use the correct torque specifications?
Using the correct torque specifications is crucial for the longevity and proper function of your MP7 transmission. Over-tightening can damage threads, stretch bolts, and potentially crack the transmission case. Under-tightening can lead to bolts loosening over time, causing fluid leaks, component failure, and even damage to surrounding parts. Correct torque ensures a secure and consistent clamping force.
Q2 Can I reuse MP7 transmission bolts?
Can I reuse MP7 transmission bolts?
While some bolts *can* be reused if they are in good condition, it's generally recommended to replace critical bolts, especially those related to the transmission casing and mounting, if they have been subjected to high stress, repeated tightening, or are showing signs of wear, like corrosion or stretched threads. This ensures the best possible and most reliable clamping force. Always inspect all bolts thoroughly.
Q3 What is the best way to apply the correct torque?
What is the best way to apply the correct torque?
The best way to apply the correct torque is to use a calibrated torque wrench. Set the wrench to the specified torque value for each bolt. Tighten the bolts in a star or criss-cross pattern gradually, in multiple stages. For example, if the final torque is 40 ft-lbs, initially torque all bolts to 20 ft-lbs in the correct pattern, then proceed to 30 ft-lbs and finally to 40 ft-lbs, making sure to follow the pattern. Never use an impact wrench for final tightening; it can easily over-torque bolts.
Q4 What happens if I don't have a torque wrench?
What happens if I don't have a torque wrench?
While it’s not recommended, if a torque wrench isn't available, you can estimate the torque by hand using a short-handled wrench, but this is highly inaccurate and risky. It’s best to borrow a torque wrench or invest in one if you are performing your own maintenance or repairs on your Acura MP7 transmission. Incorrect torque is a major cause of failures in automotive systems.
Q5 Where can I find specific torque specs for my 1994-2001 Integra's MP7 transmission bolts?
Where can I find specific torque specs for my 1994-2001 Integra's MP7 transmission bolts?
Refer to your Acura Integra's factory service manual (FSM) for the most accurate torque specifications. Alternatively, you can consult reputable automotive repair guides or databases specific to your vehicle. Online forums dedicated to Acura Integras might also offer information, but always verify the data with official sources like the FSM. Never use generic torque specifications without confirming it is specific to your component and year.
