The 4L60E transmission is a very common transmission used in light and medium duty trucks. It is also often used in high performance vehicles. There are several common problems with this type of transmission, however, that can lead to serious issues if not addressed in a timely manner.
One common problem is known as 4L60E shudder. This occurs when the torque converter clutch slips when engaging or disengaging. This can cause the vehicle to jerk or lurch when accelerating or decelerating. If left unchecked, this issue can eventually damage the transmission itself.
Another common problem with the 4L60E transmission is known as hard shifting. This occurs when the gears refuse to engage smoothly, resulting in a harsh, jarring shift. This can be caused by low fluid levels, dirty fluid, or worn parts within the transmission. Hard shifting can also lead to premature wear on the gears themselves, ultimately causing even more damage down the road.
If you suspect that your 4L60E transmission may be having any of these issues, it's important to have it checked out by a qualified mechanic as soon as possible. Ignoring these problems will only make them worse and could eventually result in costly repairs or even complete failure of the transmission.
