**Does a 700r4 Transmission Need a Computer?**

The 700r4 transmission, also known as the GM 700-R4 or 4L60, is a popular choice among automotive enthusiasts. However, there is often confusion regarding whether this transmission requires the use of a computer. In this article, we dive into this question and explore the role of a computer when using a 700r4 transmission.

**The Answer: No, a 700r4 transmission does not require a computer.**

Unlike more modern transmissions, the 700r4 was originally designed without electronic control systems. It is a mechanically controlled transmission that relies on hydraulic pressure and mechanical linkages for its operation. This makes it more straightforward to install and operate in vehicles that don’t have computer systems.
