Frequently Asked Questions (FAQs)
1. Can a leaking transmission pump seal be replaced without removing the transmission?
Unfortunately, replacing a leaking transmission pump seal typically requires removing the transmission, which can be a costly and time-consuming job. However, if removing the transmission is not feasible or practical, you can try using a transmission sealer product like BlueDevil Transmission Sealer to restore the seal and stop the leak.
2. What causes a transmission pump seal to leak?
A transmission pump seal may start leaking due to a lack of lubrication. When the seal does not have enough fluid to lubricate the materials around the shaft, it can become dry, leading to increased friction and heat. This can cause the seal to burn, melt, or become damaged, resulting in fluid leakage under pressure.
3. How much does it cost to replace a transmission seal?
The cost of replacing a transmission seal, specifically the rear transmission seal or rear main seal, can range from $600 to $900. The cost may vary depending on factors such as your location and the type of vehicle you have. This seal is located between the engine and transmission, sealing the crankshaft and preventing oil leaks.
4. Can you drive with a bad transmission seal?
While it may be technically safe to drive with a leaking transmission seal, it is not advisable to do so. Ignoring the problem and not fixing the seal can lead to further damage and potentially more expensive repairs in the future. It is recommended to address the issue promptly to prevent any complications.
5. What happens when a transmission seal goes bad?
When a transmission seal fails, it can lead to fluid leaks that can cause significant damage to the transmission. These leaks can result in fluid loss, increased friction, and overheating, ultimately leading to transmission failure. Despite their small size, transmission seal and gasket failures can have severe consequences for the overall functioning of the transmission.
6. Are transmission seals easy to replace?
Replacing transmission seals can vary in difficulty. While many seals are inexpensive and relatively easy to replace, some may be located in hard-to-reach areas that require extensive dismantling of components or even removing the entire transmission. It is generally recommended to seek professional help from a garage or mechanic for replacing transmission seals, especially those in more challenging locations.
