The Enduring Appeal of the TH350 Transmission

The Turbo-Hydramatic 350, commonly known as the TH350, is a 3-speed automatic transmission introduced by General Motors in 1969. It quickly became a staple in a vast array of GM vehicles, from muscle cars to trucks and SUVs, due to its robust design, compact size, and relatively light weight. Its simplicity made it a favorite among drag racers and custom builders, and its reliability cemented its place as one of the most successful automatic transmissions ever produced. Even today, the TH350 remains a highly sought-after unit for a wide variety of automotive projects, offering a fantastic balance of performance and affordability.

Why Choose a Rebuilt TH350?

While you might encounter offers to buy a used th350 transmission, opting for a professionally rebuilt unit from Spoon Parts USA provides significant advantages. A rebuilt transmission has been completely disassembled, cleaned, inspected, and had all worn or damaged components replaced with new or re-machined parts. This process restores the transmission to its original factory specifications, and often, even improves upon them with updated materials and techniques. This means you get a transmission that performs like new, often surpassing original factory durability, without the guesswork and potential headaches associated with uninspected, used components. Avoid the pitfalls of an unknown history; choose a meticulously rebuilt TH350 from Spoon Parts USA.

Key Features and Specifications of Our Rebuilt TH350 Transmissions

Our rebuilt TH350 transmissions are engineered for reliability and performance. Here’s what you can expect:

• Complete Disassembly and Inspection: Every unit is taken apart, and all components are thoroughly cleaned and inspected for wear and damage.
• New Friction Materials: All clutches and bands are replaced with high-quality, new friction materials for optimal shift quality and durability.
• New Gaskets and Seals: Comprehensive replacement of all gaskets, seals, and O-rings prevents leaks and ensures long-term integrity.
• Updated Bushings and Bearings: All critical bushings and bearings are replaced to reduce internal friction and enhance operational smoothness.

Core Components and Upgrades

During the rebuilding process, we pay close attention to critical components. This includes the direct drum, forward clutch drum, and intermediate sprag assembly. Depending on the intended application, we can also incorporate performance upgrades, such as heavy-duty clutches, Kevlar bands, and improved direct drums, to handle higher horsepower and torque demands. These enhancements ensure that your rebuilt TH350 not only meets but exceeds expectations, whether for a daily driver or a weekend warrior. We ensure our quality is on par with, if not superior to, options you might traditionally find from places like monstertransmission.com is blocked, always focusing on supreme durability and performance for our customers.

Applications and Fitment

The TH350 transmission was factory-installed in a wide variety of Chevrolet, Pontiac, Oldsmobile, and Buick vehicles from the late 1960s through the early 1980s. Popular applications include:

• Chevrolet Camaro, Chevelle, Nova, Impala, C/K Series Trucks
• Pontiac Firebird, GTO, LeMans, Grand Prix
• Oldsmobile Cutlass, 442, Ninety-Eight
• Buick Skylark, LeSabre, Riviera

Its adaptability also makes it a popular swap for many other classic cars and hot rods, often replacing Powerglides or earlier 3-speed automatics. Our team can help you verify fitment for your specific vehicle and engine combination. When you’re considering a new transmission, for example, a SportMonster Chevy TH350 – Transmission & Torque Converter, always double-check the case type (long or short tail shaft) and spline count for compatibility.

Installation Notes and Tips

While installing a TH350 can be straightforward for experienced mechanics, proper procedures are crucial for optimal performance and longevity:

• Fluid Type: Always use the correct type of automatic transmission fluid (ATF), typically Dexron III/Mercon for most TH350 applications.
• Cooler Lines: Ensure transmission cooler lines are clean and free of obstructions. Consider adding an auxiliary cooler for high-performance or heavy-duty applications.
• Adjustments: Proper vacuum modulator and throttle valve (TV) cable adjustments are critical for correct shift points and preventing premature wear.
• Flexplate Selection: Verify you have the correct flexplate for your engine and torque converter combination.
• Filler Tube and Dipstick: Always use the correct length filler tube and dipstick for accurate fluid level readings.

If you’re unsure about any aspect of installation, we recommend consulting a professional transmission shop. Our goal is for your rebuilt TH350 to provide flawless service, and proper installation is key.
