FAQ: 700R4 Transmission
What years was the 700R4 transmission used?
The 700R4 was primarily used from 1982 to 1993. In 1990, it was renamed the 4L60, but it was essentially the same transmission with some internal improvements.
Is the 700R4 a good transmission?
Yes, the 700R4 is generally considered a good transmission, especially when properly maintained. Early models had some reliability issues, but later versions and upgraded units are quite durable.
What is the difference between a 700R4 and a 4L60E?
The 700R4 (later 4L60) is hydraulically controlled, while the 4L60E is electronically controlled. This means the 4L60E requires a computer to manage its shifting, while the 700R4 relies on mechanical and hydraulic components.
So, there you have it – a comprehensive look at the cars that proudly sported the 700R4 transmission. It’s a testament to its versatility and impact on the automotive landscape. Whether you’re restoring a classic or considering a transmission swap, understanding the 700R4 is essential. Hopefully, this guide has shed some light on this iconic piece of automotive engineering. Happy wrenching!
Identifying a 700R4 Transmission: Key Features
Alright, let’s say you’re at a swap meet or junkyard, and you need to positively identify a 700R4. What do you look for? Don’t worry, I’ve got you covered. It’s not just about knowing the cars it came in; it’s about recognizing the transmission itself.
The Shape and Pan of the 700R4 Transmission
The 700R4 has a distinctive shape. The most telling feature is the square-shaped pan with a beveled corner. This is a dead giveaway. The TH350, for example, has a more rectangular pan. Remember this, and you’ll be ahead of the game.
The TV Cable: A Crucial Component of the 700R4 Transmission
The Throttle Valve (TV) cable is absolutely critical for the 700R4 to function correctly. It’s connected to the carburetor or throttle body and controls the transmission’s line pressure. Without a properly adjusted TV cable, you’re looking at a quick and expensive rebuild. Trust me on this one!
- Check the Cable: Ensure the TV cable is present and in good condition.
- Adjustment is Key: Proper adjustment is paramount. Don’t skip this step!
Important Note: The TV cable is NOT a kickdown cable. It’s responsible for line pressure and shift timing. Misunderstanding this can lead to serious transmission damage.
The Governor Cover: Another Identifying Mark of the 700R4 Transmission
Located on the side of the transmission, the governor cover is another way to identify a 700R4. It’s a round cover, typically held in place by a few bolts. While other transmissions have governor covers, the overall shape and location on the 700R4 are distinctive.
So, you’ve got a 700R4, and you’re thinking about boosting its performance? Excellent! The 700R4 has a lot of potential, but it can benefit from some upgrades, especially if you’re planning on running more power or putting it through some serious abuse.
A shift kit is one of the most common and effective upgrades for a 700R4. It modifies the valve body to provide firmer, quicker shifts. This not only improves performance but also helps to extend the transmission’s lifespan by reducing slippage.
The torque converter is another crucial component to consider upgrading. A higher stall speed torque converter allows the engine to rev higher before the transmission starts to engage, improving acceleration. However, it’s important to match the stall speed to your engine’s powerband and intended use.
If you’re building a high-performance 700R4, consider upgrading to hardened components. This includes things like hardened shafts, drums, and planetary gears. These parts are designed to withstand the increased stress of high horsepower and torque.
