( Manufacturer Part Number: THH350 ), ( Part Type: Leak Transmission Motor )
The TH350 Turbo 350 transmission is a legendary automotive component, renowned for its durability and reliability in various applications. This particular model, the TH350 General, is a direct descendant of the original TH350 transmission, engineered to provide optimal performance and longevity.
The TH350 General transmission features a three-speed automatic design, making it an excellent choice for a wide range of vehicles. Its robust construction, including a heavy-duty cast iron case, ensures that it can withstand the rigors of daily driving, towing, and high-performance applications.
One of the key attributes of the TH350 General transmission is its leak-resistant design. However, like any mechanical component, it can develop leaks over time due to wear and tear or damage. The transmission leaks you may encounter with this model are typically related to the seals and gaskets that keep the transmission fluid inside the casing.
Common leak points include the pan gasket, input shaft seal, and the transmission oil pump seal. These leaks can manifest as a puddle of transmission fluid on the ground, or you may notice a burning smell from the exhaust due to oil consumption.
When it comes to diagnosing and repairing leaks in the TH350 General transmission, it's essential to identify the source of the leak accurately. This may involve inspecting the transmission for signs of wear, checking for loose bolts or damaged seals, and performing a pressure test.
Replacing seals and gaskets is a relatively straightforward process, but it requires careful attention to detail to ensure a proper fit and avoid further leaks. In some cases, it may be necessary to replace entire components, such as the transmission pan or the oil pump, to address the leak.
In conclusion, while the TH350 General transmission is renowned for its reliability, it is not entirely leak-proof. Regular maintenance and prompt attention to any signs of leaks can help extend the life of the transmission and prevent costly repairs. Whether you're a DIY enthusiast or a professional mechanic, understanding the common leak points and repair procedures for the TH350 General transmission can help you keep your vehicle running smoothly for years to come.
Pros of buying a used TH350 transmission with a known leak:1. Cost: A used transmission with a known leak is often significantly cheaper than a rebuilt or new one.
2. Availability: Used transmissions are widely available, which can make it easier to find a suitable match for your vehicle.
3. Familiarity: The TH350 is a popular and well-known transmission, which means there is a wealth of information and resources available to help you diagnose and repair any issues.
Cons of buying a used TH350 transmission with a known leak:1. Repair Costs: While the upfront cost of a used transmission may be lower than that of a rebuilt or new one, repair costs can quickly add up. The leak may be a symptom of other underlying issues that need to be addressed.
2. Reliability: Used transmissions may not be as reliable as rebuilt or new ones. They may have wear and tear that can lead to further problems down the line.
3. Longevity: A used transmission may not last as long as a rebuilt or new one, especially if it has been poorly maintained or abused.
Recommendation:While a used TH350 transmission with a known leak can be a cost-effective option, it's important to weigh the pros and cons carefully. If you're mechanically inclined and have the time and resources to diagnose and repair any issues, a used transmission may be a good option. However, if you're not confident in your ability to do this, it may be wiser to invest in a rebuilt or new transmission to ensure reliability and longevity. Ultimately, the decision should be based on your budget, time, and comfort level with automotive repair.
The transmission work's fine behind the big block, comes with torque converter, yoke on tail shaft and shiftier. I'm playing with a 1963 impala ss with a big block 402 in it. This transmission came out of my car which I purchase a few months ago, it is in good working order when it was removed about a week ago to install a 4 speed manual transmission. No dip stick.
I looked on the internet to try and find some info on this transmission, all I can tell you they were used from 1969 to 1989.
