The Turbo Hydra-Matic 700-R4 is a very strong GM transmission and was used extensively in the GM family of cars for over 10 years. The electrical connector for this solenoid is on the driver’s side of the transmission case. From 1982-1984, the TH700R4 came with a 27-spline input shaft.
What is the difference between a 700R4 and a th700?
The full “name” is TH700r4… some people refer to it a 700r4, etc…. so yes, they are the same.
Is the 700R4 transmission any good?
The 700R4, produced by General Motors/Hydramatic, is considered one of the best overdrive transmissions ever made. This transmission had a lower first gear ratio, which was good for performance at low vehicle speeds, while the 30% overdrive provided significant fuel economy improvement.
Will a 700R4 replace a TH350?
If your original TH350 came with a 6-inch tail shaft, you’ll have to cut the drive shaft by 3 inches. The 700R4’s drive shaft yoke is identical to the TH350’s, so your old yoke should work nicely with the new transmission.
What’s better 700R4 or 4L60E?
You can’t tell the difference between a 700R4 and a 4L60E by the oil pan as they are nearly the same. If it has a cable connection near the cooler lines on the passenger’s side, that’s a 700R4. The good news is that either way, you win.
How can you tell a Turbo 350 from a 700R4?
The shape of the oil pans is one way to differentiate between the TH350 and the 700R4. The TH350’s oil pan is shaped like a square with one of its corners cut off, while the 700R4’s oil pan is basically rectangular.
