Frequently Asked Questions
Is a TH350C a good transmission?
Surprisingly, the transmission doesn't have too many issues, but there are some inherent design flaws when this transmission is used in high-performance applications. First on the list is the race that rests between the high-gear drum and the secondary drum.
What is a Turbo 350c transmission?
The th350 is a 3 speed transmission, the 350c is a 3 speed that uses a lock up converter. An overdrive and a lock up converter are two different things. An overdrive has a ratio that is lower (numerically) than 1:1, such as . 76:1...
What is the weakness of the 700R4?
Problems With the 700R4
Early 700R4 transmissions came with the less desirable 27-spline input shaft. Later units, those produced after 1984, featured 30-spline input shafts. In high-power applications the lower spline count can be more likely to break.
What vehicles came with a TH350C?
The HydraMatic 350 transmission was prevalent in nearly all GM, rear-wheel-drive cars and trucks through 1984. It was typically paired with Small Block V6 & V8 engines.
How do I know if I have a TH350C?
On the driver's side of the transmission, about halfway along the length of the main body of the transmission, the presence of a 4-prong connector means you have a TH350C (lockup).
What is a turbo 350c?
The th350 is a 3 speed transmission, the 350c is a 3 speed that uses a lock up converter. An overdrive and a lock up converter are two different things.
What is the difference between TH350 and TH350C?
The internals are exactly the same between a th350 and th350c. The only differences are the input shaft and pump cover and they are only different in length to accommodate the lock up converter.
What years did Chevy trucks have bad transmissions?
Transmission Problems
These transmission issues can be caused by failed shift solenoids or by issues with the software in the car's PCM. Model years particularly affected include 2002, 2012, and 2017. Chevrolet's even faced several recalls thanks to these problems.
Which GM transmission is strongest?
The 10L90E is by far the biggest and heaviest modern automatic transmission in GM history, but it's also the strongest and offers amazing performance and economy when matched with a Gen V LT engine. This is part of the newest technology in the performance world.
How do I tell if I have a TH350 or TH400?
Check the Connection. There's a cable that may be connected to the transmission's side and next to the location of the shifter linkage.
