The basic function of a transmission pan is required when automatic transmissions are present, as it holds all of the automatic transmission fluid, otherwise referred to as ATF. For fluid pressure, cooling, and lubrication, the ATF is essential. Additionally, it has other functions as well that include extending the temperature range, preventing rust, conditioning the gaskets, as well as preventing fluid oxidation. But since the automatic transmission fluid needs somewhere to go, the transmission pan is strategically placed. The transmission pan not only holds the ATF but it has additional benefits that include the following:
– In the ATF through the pan’s magnet, any dirt or debris is collected.
– Before it goes back into the transmission, the transmission pan helps cool the ATF.
– Acts as a barrier for the ATF from foreign contaminants.
– Offers protection from objects on the road such as rocks that can cause a leak.
– Prevents any fluid from leaking out by the transmission pan gasket. There are common problems that inflict the automatic transmissions that many people know about and transmission pans are equally susceptible to problems. Despite the simplistic nature of the transmission oil pan, more problems can arise than you may suppose.
Transmission Pan Gasket Fluid Leaks from Cracked Pans, Loose Bolts & Physical Damage
Common problems of transmission pans include:
– A contributing cause to fluid to leak out, the pan gaskets can slip out of position or crack from age.
– Leaks manifest due to loose transmission pan bolts or drain plugs.
– A large dent that results in reduced fluid capacity can be produced by using a floor jack to lift a vehicle by the pan.
– Potentially causing a puncture that will have ATF leaking out from a large object that struck the transmission oil pan. If the hole is beg enough, a large amount of fluid loss can occur in a short amount of time. The results cause very erratic transmission behavior.
Transmission Pan Cleaning & Maintenance Tips
In an effort to avoid transmission pan problems, below you will find some tips and advice that includes basic maintenance steps.
1) When you go to seal the pan, avoid using RTV sealants and cork-based gaskets. Cork gaskets are not made of quality materials and they crack easily over time. Not only do sealants create residue that can contaminate the ATF and stick to the pan, but it also makes the pan a challenge to remove when you need to again. Using the reusable rubber transmission pan gasket is optimal for preventing leaks and since it is made of higher quality, it makes fluid changes easier and lasts longer.
2) Each time you change your fluid, inspect the pan gasket; check for any signs of damage or deterioration such as it being warped, cracked, or broken. If any exist, get it replaced.
3) Routinely evaluate the transmission oil pan condition and ensure there are no leaks, if any issues are found, replace the pan.
4) Always have the pan cleaned as well as the magnet that collects metal shavings when you have a fluid change performed.
5) According to manufacturer specifications, have the transmission pan tightened. Applying this step can help the pan avoid damage, as well as the gasket from getting crushed, and ensures the bolts are tight enough to prevent any leaks
6) Be sure to start from the center bolts and continue out in a criss-cross pattern when tightening pan bolts to distribute even pressure on all sides.
