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 proper torque important when installing transmission bolts?
Why is proper torque important when installing transmission bolts?
Proper torque ensures the bolts are tight enough to hold components securely without being too tight, which can strip threads or distort parts. Under-torquing can lead to leaks and component failure due to movement. For example, if the valve body bolts are not tightened to spec, internal leaks can occur, causing shifting issues. Over-tightening the pan bolts could crush the gasket causing leaks
Q2 What happens if I over-torque a transmission bolt?
What happens if I over-torque a transmission bolt?
Over-torquing can stretch or break bolts, damage threads in the transmission case, distort the mounting surfaces, and compress gaskets unevenly leading to leaks. Imagine over-tightening the transmission pan bolts - you could easily warp the pan, making it difficult to seal properly even with a new gasket.
Q3 What happens if I under-torque a transmission bolt?
What happens if I under-torque a transmission bolt?
Under-torquing can cause bolts to loosen over time due to vibration and use. This can lead to oil leaks, internal component damage, and even complete failure of the transmission if critical components come loose. For example, a loose bell housing bolt could cause misalignments and gear problems.
Q4 Can I reuse old bolts after removing them?
Can I reuse old bolts after removing them?
Generally, it's recommended to use new bolts, especially for critical components like the bell housing or valve body. Old bolts may have stretched or fatigued, affecting their torque holding capability. Always inspect all removed bolts, look for signs of corrosion and damage before reusing. However, when following procedure use new bolts. Reusing pan bolts on occasion can be done safely if inspected first, but new is recommended.
Q5 Do I need to use a special thread locking compound?
Do I need to use a special thread locking compound?
For most 41TE bolts, thread locking compounds are not required by factory service procedures. However, it may be beneficial on bolts subject to heat and vibration. Always refer to the specific procedure and if it specifies a locking compound use the type identified. For example, some valve body bolts might have a small amount of locking compound pre-applied or a spec may require it to be applied
Q6 What is the difference between 'ft-lbs' and 'in-lbs' in torque specifications?
What is the difference between 'ft-lbs' and 'in-lbs' in torque specifications?
Foot-pounds (ft-lbs) and inch-pounds (in-lbs) are units of torque. Foot-pounds are larger units of torque, used for higher torque requirements (like bell housing bolts). Inch-pounds are smaller units of torque, used for lower torque requirements (like valve body bolts). 1 ft-lb = 12 in-lbs. Use the proper tool for the correct measurement, i.e. a torque wrench with the correct measurement.
