- Install the new pan:Carefully lift the new pan into place and align it with the transmission case. Hand-tighten the bolts to hold the pan in place.
- Tighten the bolts:Use a torque wrench to tighten the bolts to the specified torque (10-12 ft-lbs). Follow a star pattern to ensure even tightening.
- Install the filter and gasket:Apply a small amount of transmission fluid to the filter gasket and install it in the transmission case. Hand-tighten the filter and then use a torque wrench to tighten it to the specified torque (20-25 ft-lbs).
- Reinstall the drain plug:Clean the drain plug and apply a new washer. Install the drain plug and tighten it to the specified torque (15-20 ft-lbs).
- Add transmission fluid:Add the recommended amount of transmission fluid to the transmission. Check the fluid level and add more as needed.
Tips and Tricks
- Use a new transmission pan gasket every time you replace the pan.
- Clean the mating surfaces thoroughly to ensure a leak-free seal.
- Tighten the bolts evenly and to the specified torque to prevent leaks.
- Use a torque wrench to ensure the filter is tightened to the correct torque.
- Check the transmission fluid level after installation and add more as needed.
TH350 Transmission Pan Maintenance
Maintaining a TH350 transmission pan is essential for ensuring the proper functioning and longevity of the transmission. The pan serves as a reservoir for the transmission fluid, which lubricates and cools the transmission’s internal components. A well-maintained pan will help to prevent leaks, contamination, and premature wear.
There are several different types of maintenance that are required for a TH350 transmission pan:
- Inspection:The pan should be inspected regularly for leaks, cracks, or damage. Any damage should be repaired or replaced as soon as possible.
- Cleaning:The pan should be cleaned periodically to remove any dirt, debris, or metal shavings that may have accumulated. This can be done by removing the pan and washing it with a mild detergent and water.
- Fluid change:The transmission fluid should be changed according to the manufacturer’s recommended schedule. This will help to keep the fluid clean and free of contaminants.
- Filter replacement:The transmission filter should be replaced at the same time as the fluid is changed. This will help to remove any contaminants from the fluid and protect the transmission’s internal components.
The following is a schedule for regular maintenance tasks for a TH350 transmission pan:
- Inspection:Every 6 months or 10,000 miles
- Cleaning:Every 12 months or 20,000 miles
- Fluid change:Every 24 months or 30,000 miles
- Filter replacement:Every 24 months or 30,000 miles
TH350 Transmission Pan Troubleshooting
TH350 transmission pans can encounter various issues that require troubleshooting. These issues can range from leaks to damage, and timely resolution is crucial to ensure optimal transmission performance and prevent further complications.
Common problems associated with TH350 transmission pans include:
- Leaks
- Damage
- Loose bolts
Leaks
Leaks in a TH350 transmission pan can occur due to several reasons, including:
- Damaged gasket
- Loose bolts
- Cracked pan
To troubleshoot leaks, inspect the gasket for any tears or damage. If the gasket is damaged, it needs to be replaced. Additionally, ensure that all bolts are properly tightened to prevent leaks. In case of a cracked pan, replacement is necessary.
Damage
Damage to the TH350 transmission pan can result from various factors, such as:
- Impact
- Corrosion
- Overtightening of bolts
If the pan is damaged, it is essential to assess the extent of damage. Minor dents or scratches may not require immediate replacement, but significant damage or cracks necessitate replacement to prevent leaks and ensure proper transmission operation.
Loose Bolts
Loose bolts on the TH350 transmission pan can lead to leaks and potential damage. It is crucial to regularly inspect the bolts and ensure they are properly tightened. Loose bolts can be tightened using a torque wrench to the specified torque value.
TH350 Transmission Pan Upgrades
Upgrading the transmission pan on a TH350 transmission can provide several benefits, including increased oil capacity, improved cooling, and enhanced durability. Here are a few popular upgrades to consider:
Deep Sump Pan, Th350 transmission pan
A deep sump pan increases the oil capacity of the transmission, which helps to keep the oil cooler and reduces the risk of overheating. This is especially beneficial for high-performance applications or vehicles that are used for towing or hauling heavy loads.
Finned Pan
A finned pan has fins that extend from the bottom of the pan, which increases the surface area for heat dissipation. This helps to keep the oil cooler and can improve the transmission’s overall performance.
Baffled Pan
A baffled pan has internal baffles that help to prevent oil from sloshing around inside the pan. This can help to improve oil flow and reduce the risk of cavitation, which can damage the transmission.
Magnetic Pan
A magnetic pan has a magnet on the bottom that attracts metal particles from the oil. This helps to keep the oil clean and can extend the life of the transmission.
Recommendation for Specific Applications
The best upgrade for a specific application will depend on the vehicle’s use and driving conditions. For example, a deep sump pan is a good choice for high-performance applications or vehicles that are used for towing or hauling heavy loads.
A finned pan is a good choice for vehicles that are driven in hot climates or that are used for racing. A baffled pan is a good choice for vehicles that are driven in off-road conditions or that are prone to cavitation.
A magnetic pan is a good choice for vehicles that are driven in dusty or dirty conditions.
