The 4L60E transmission is a popular automatic transmission used in many vehicles. It is known for its durability and smooth shifting. One common question that arises when working on or replacing this transmission is the number of bolts it has.
Understanding the Transmission
Before we delve into the number of bolts, let’s briefly understand the 4L60E transmission. It is a four-speed overdrive transmission that was introduced by General Motors in the early 1990s. It is commonly found in rear-wheel drive vehicles and is known for its reliability.
The Number of Bolts
The 4L60E transmission has a total of 16 bolts. These bolts are used to secure the transmission to the engine block and the transmission pan. The 16 bolts are evenly distributed around the transmission housing.
Transmission Pan Bolts
Out of the 16 bolts, 14 of them are used to secure the transmission pan. The transmission pan is located at the bottom of the transmission and houses the fluid. It needs to be removed in order to access the internal components of the transmission.
Engine Block Bolts
The remaining two bolts are used to secure the transmission to the engine block. These bolts are located at the back of the transmission, where it connects to the engine. They are usually larger in size compared to the transmission pan bolts.
Importance of Bolt Tightening
When working on the 4L60E transmission, it is crucial to ensure that the bolts are tightened properly. Over-tightening or under-tightening the bolts can lead to leaks or damage to the transmission. It is recommended to follow the manufacturer’s specifications for torque values and use a torque wrench for accurate tightening.
In conclusion, the 4L60E transmission has a total of 16 bolts. 14 of these bolts are used to secure the transmission pan, while the remaining two bolts are used to secure the transmission to the engine block. Proper tightening of these bolts is essential to ensure the transmission functions smoothly and without any leaks. When working on the 4L60E transmission, it is always advisable to consult the manufacturer’s guidelines and use the appropriate tools for the job.
