What You'll Learn
GM Turbo 400 transmission pan kits include 13 bolts
The GM Turbo 400 transmission pan kits include 13 bolts, as well as 13 washers. These kits are designed for use with GM Turbo 350 and GM Turbo 400 transmission pans. The bolts are made of zinc-plated steel and are designed to fit the specific thread pattern of the GM Turbo transmission pans.
The GM Turbo 400 transmission pan is a popular choice for many car enthusiasts, as it offers a strong and durable option for those looking to improve the performance of their vehicle. The transmission pan is responsible for holding the transmission fluid, which lubricates and cools the transmission components.
By using a GM Turbo 400 transmission pan with the correct number of bolts, you can ensure that the pan is securely attached to the transmission, preventing leaks and potential damage. Leaks can not only result in a loss of fluid but also lead to contamination of the fluid, which can cause damage to the transmission.
It is important to note that when installing a transmission pan, it is crucial to follow the correct torque specifications for the bolts. Over-tightening the bolts can strip the threads or damage the pan, while under-tightening can lead to leaks. It is recommended to refer to a repair manual or seek professional assistance to ensure proper installation.
In addition to the bolts and washers included in the kit, it is also important to use the correct gasket when installing the GM Turbo 400 transmission pan. The gasket creates a seal between the pan and the transmission, preventing leaks and ensuring the proper function of the transmission system.

The bolt kit is made from zinc-plated steel
The bolt kit for the GM Turbo 400 transmission pan is made from zinc-plated steel. This type of steel offers superior corrosion resistance, ensuring that the bolts remain sturdy and intact for the long term. The zinc plating provides a protective barrier that shields the steel from the elements, inhibiting oxidation and rust formation.
Zinc-plated steel is an ideal material for the bolt kit due to its durability and resistance to wear and tear. The plating process involves coating the steel bolts with a thin layer of zinc, which not only enhances corrosion protection but also improves the bolt's overall strength and fatigue resistance. This makes the bolts less susceptible to breakage or failure over time.
The zinc-plated steel bolts in the kit are designed to meet the specific requirements of the GM Turbo 400 transmission pan. They are manufactured with precision, ensuring that they fit securely and effectively fasten the transmission pan in place. The bolts are engineered to withstand the vibrations and stresses associated with the operation of the transmission, providing a reliable and long-lasting solution.
In addition to the zinc-plated steel bolts, the kit also includes zinc-plated washers. These washers are designed to distribute the load and pressure evenly, reducing the risk of damage to the transmission pan and ensuring a secure fit. The washers, like the bolts, benefit from the corrosion-resistant properties of the zinc plating, further enhancing the overall durability of the assembly.
The use of zinc-plated steel in the bolt kit reflects the attention to detail and quality that goes into the GM Turbo 400 transmission pan assembly. This choice of material ensures that the bolts can withstand the demanding conditions they are subjected to, providing peace of mind and confidence in the performance and longevity of the transmission system.

The bolt kit is also available in black aluminium
The GM Turbo 400 transmission pan bolt kit typically includes 13 bolts and 13 washers. These kits are usually made from zinc-plated steel, but there are alternatives available.
One such alternative is the Assault Racing Products A8492PBK GM Chevy Turbo 400 Black Aluminum Transmission Pan Kit. This kit is made from black cast aluminum and includes a gasket, bolts, and washers. The bolts and washers are metric, and the gasket is made of rubber. This kit is a good choice for those seeking an alternative to the standard zinc-plated option, and it is available for purchase online.
It is important to note that some reviewers have noted that the thread fit of the bolts in this kit is too loose, and the bolts may not be long enough for some applications. Additionally, some holes may require modification before installation, as they may be covered with casting flash. Despite these potential issues, the Assault Racing Products kit has received positive reviews for its well-made parts and ease of installation.
The bolt kit is also available in black aluminum, offering an aesthetically pleasing and durable option for those seeking an alternative to the standard zinc-plated bolts. This option provides a unique look while maintaining the functionality and performance of the transmission pan.

The bolts are tightened to stop leaks
The GM Turbo 400 transmission pan bolt kit typically includes 13 bolts and 13 washers. The bolts need to be tightened to prevent leaks, and it is important to exercise caution during this process. Firstly, it is recommended to install all the bolts that go through the crossmember to the frame without tightening them, allowing for the alignment of the crossmember-to-transmission-mount bolts. Once all the fasteners are in place, tighten the crossmember bolts first, followed by the bolts to the transmission rear mount.
During the installation process, it is crucial to spin the torque converter to ensure it is not binding. Install the bolts individually, but refrain from fully tightening them until all bolts are in place. If there is insufficient clearance or the torque converter is too tight against the flexplate, stop the process immediately. Additionally, when tightening the bolts, it is advised to slowly tighten them evenly while pulling the transmission towards the engine. Reaching in and spinning the torque converter during this step ensures that it does not bind in the engine's crankshaft.
It is important to note that the torque converter may cause issues. Before installing and tightening the torque converter bolts, test fit the new converter to the back of the crankshaft to ensure the hub is fully seated. Some flexplates may not have the required bolt pattern for the new converter, and high-performance converters may necessitate larger-diameter bolts. Therefore, it is beneficial to verify if the flexplate holes require enlargement before proceeding.
Furthermore, some aftermarket torque converters require custom hardware, and it is recommended to use grade-8 material for these components. Soft nuts and bolts can loosen and lead to significant problems. When tightening the transmission cooling lines, it is important to hold the fittings with a second wrench to prevent them from moving. Additionally, ensure that the transmission fittings do not turn when tightening the cooling lines.
To summarise, when tightening the bolts in a GM Turbo 400 transmission, it is important to follow specific procedures to prevent leaks. This includes properly installing and tightening bolts, addressing torque converter issues, and ensuring the correct use of hardware and tools to avoid potential problems.

The bolts are not long enough, according to one reviewer
The GM Turbo 400 transmission pan is typically accompanied by a 13-piece bolt kit. While the bolt kit is designed for the GM Turbo 400 transmission pan, one reviewer has commented that the bolts are not long enough.
It is important to note that the length of the bolts in a transmission pan bolt kit can vary depending on the specific application and the manufacturer. In this case, the reviewer may have a different model or version of the GM Turbo 400 transmission pan, which requires longer bolts for proper installation.
To ensure the correct bolt length, it is recommended to refer to the manufacturer's instructions or specifications for the specific transmission pan model and its corresponding bolt kit. Each manufacturer will design their bolt kits to meet the exact specifications of their transmission pans, ensuring a secure fit and optimal performance.
Additionally, when purchasing a bolt kit, it is advisable to verify the thread pitch and diameter of the bolts to guarantee compatibility with the transmission pan. In some cases, as mentioned in the review, certain bolts may not have the correct thread pitch or diameter, leading to potential installation issues. Therefore, checking these specifications before purchase can help avoid such problems.
By considering the manufacturer's instructions and specifications, as well as verifying the thread pitch and diameter of the bolts, individuals can ensure they select the appropriate bolt kit with bolts of sufficient length for their GM Turbo 400 transmission pan.
