RTV glue can be used to seal transmission pans without gaskets
One advantage of using RTV glue instead of a gasket is that it can provide an excellent seal. In some cases, people have found that using RTV glue has resulted in a better seal than using a gasket, preventing leaks and ensuring smooth transmission performance. Additionally, RTV glue can be easier to work with than gaskets, as it can be applied directly to the sealing surfaces without the need for additional tools or complex installation processes.
However, there are also potential drawbacks to using RTV glue instead of a gasket. One issue is that RTV glue can be difficult to remove once it has been applied. If the transmission pan needs to be serviced or replaced in the future, it can be challenging to separate the pan from the sealing surface due to the strong adhesion of the RTV glue. In some cases, prying or using tools to separate the pan may be necessary, which can damage the pan or the sealing surface.
Another consideration when using RTV glue is compatibility. Not all types of RTV glue are compatible with transmission fluid, and using the wrong type of RTV can cause issues. It is important to use a type of RTV that is specifically designed for use with transmission fluid, such as those offered by Stellantus, Permatex, or Threebond. Using the incorrect type of RTV can result in leaks or damage to the transmission.
Overall, while RTV glue can be used to seal transmission pans without gaskets, it is important to carefully consider the advantages and potential drawbacks. RTV glue can provide an excellent seal and be easier to work with than gaskets, but it may also be difficult to remove and require careful selection to ensure compatibility with transmission fluid. It is always recommended to consult a professional or refer to the vehicle's manual before making any modifications or repairs to the transmission pan.

Gaskets are designed to seal and some are reusable
Gaskets are mechanical seals designed to prevent leaks between two surfaces. They are typically used for static applications, such as joints, flanges, and other mating surfaces, where they fill irregularities and create a tight seal. They are commonly made from rubber, plastic, metal, or other materials depending on the specific application.
In dynamic environments, such as rotating shafts, pumps, and engines, seals are used instead of gaskets. Seals are typically flat and round, with a tilted inner ring of rubber and a metal outer ring. They prevent leaks between two moving parts and protect against the intrusion of contaminants.
Some gaskets are designed to be reused, while others are intended for single use. For example, the coloured seal (RTJ seal) is not suitable for reuse due to its small load area, which results in high surface pressure between the sealing surface and the groove. On the other hand, gaskets used in food processing and beverage bottling may be reused, as they serve to prevent leaks and cross-contamination during the filling of bottles or in the preparation of food.
When it comes to transmission pan gaskets, there are different opinions on whether adhesives should be used. Some people prefer to use adhesives like Permatex Ultra Black or RTV silicone on both sides of the gasket for a better seal and easier removal. Others suggest that no adhesives are needed for "rubbery" type gaskets, and that coatings like ATF can help the gasket seat properly. Ultimately, it may depend on personal preference and the specific application.

Sealant can cause the gasket to squeeze out and reduce the sealing area
While some people recommend using sealants like RTV silicone, gasket glue, or Permatex Ultra Black on transmission pan gaskets, others advise against it. One of the main reasons for this is that the use of sealant can cause the gasket to squeeze out and reduce the sealing area. This is especially true for rubber gaskets, where the sealant can make the gasket slippery, causing it to be pushed out when the bolts are tightened. This can result in leaks and create a mess that requires extensive cleaning.
Some people prefer to use a flat type of gasket that does not require any sealant and can be easily pried off without bending. Others suggest using a thin coat of a product like K&W Copper Coat or gasket glue sparingly on one side of the gasket to hold it in place during installation. This is often done on cork gaskets, while rubber gaskets typically do not require any adhesives.
It is important to follow the manufacturer's recommendations and use the correct type and amount of sealant to avoid issues. Some sources suggest that transmission fluid can eat through certain types of sealants, and small pieces of sealant can get into the valve body and cause problems. Therefore, it is crucial to use the appropriate products and follow the recommended dry times to ensure a proper seal and prevent leaks.
Overall, while sealants can be used with transmission pan gaskets, they should be used with caution to avoid the gasket being squeezed out and reducing the sealing area. It is essential to consider the type of gasket, follow instructions, and use the correct amount of sealant to ensure a proper seal and prevent potential issues.

Gaskets made of rubber do not require adhesives
When it comes to transmission pan gaskets, there are a variety of options available, and the choice between using adhesives or not depends on the specific application and gasket material. Rubber gaskets, for instance, typically do not require adhesives.
Rubber gaskets are commonly used in various applications, including in cars, due to their flexibility, durability, and ability to create a tight seal. In some cases, rubber gaskets can be mechanically fastened using bolts or screws, eliminating the need for adhesives altogether. This is often seen in classic car engines, where the gasket is secured in place with bolts.
For transmission pans, rubber gaskets are often used without any adhesives. This is because rubber gaskets are flexible and can conform to the shape of the transmission pan, creating a tight seal without the need for additional adhesives. The rubber gasket's thickness and durability allow it to absorb the force exerted on it, preventing leaks effectively.
However, some people prefer to use adhesives with rubber gaskets for added security. High Tack adhesive, for example, can be applied to both sides of the gasket to enhance its adhesion. Gaskets made of other materials, such as cardboard or paper, may also benefit from adhesives like Permatex High Tack or Gasacinch to hold them in place. Additionally, some demanding applications may use both mechanical fasteners and adhesives for extra security.
While adhesives can provide benefits in certain situations, it is important to consider their potential drawbacks. For instance, uneven application of adhesives can lead to leaks, and the curing time of sealants can slow down the gasket installation process. Therefore, when using adhesives, it is crucial to ensure an even application and follow the manufacturer's instructions for curing time.
