4l60e Transmission Issues Troubleshooting And Solutions
If you're suffering from 4L60E transmission troubles, you're far from isolated. In this post, we'll take an in-depth look at the 4L60E transmission, and the most common issues that are associated with it. We will discuss some of the indicators and what it could mean for the transmission. For more information and specifications on the used 4L60E transmission.
Before we dive into the 4L60E transmission problems you could have, it's important to know the mechanism of transmission. This part can be skipped and we'll get straight into the transmission issues. Let's continue.

A BRIEF HISTORY OF 4L60E TRANSMISSION
The 4L60E transmission is one of the most popular and well-known on the US car market in the present.
It was manufactured by GM (General Motors) and first appeared in 1992. The product was then able to enter the marketplace over the course of two years. Numerous upgrades followed, with different levels of importance. One of the most significant was the launch in the year 1996 of a bell that bolts onto the house (phased in between 1996 and 1998).
It first came into commercial use in 1993-94 on cars like the Chevrolet Suburban and Cadillac Fleetwood.
It was a successor to the 4L60. The prior transmission was called the TH700R4 (Turbo-Hydromatic 700R4) and had been launched in 1982. In the year 1990, GM altered its designations, and so the 700R4 was changed to "4L60".
This stood for:
4 forward gears
Longitudinal applications (rear wheel-drive)
The transmission can safely haul up to 6,000 pounds of car with it having a gross vehicle weight (GVW) of 6000 pounds
The 4L60 and other transmissions in its generation, was operated by the hydraulic system. This means that a sequence of valve pressures caused the transmission shift gears.
GM have made the switch to electronic shifting control using the 4L60E (Electronic shifting control). Keep scrolling to find out more about electronic shifting, and the numerous benefits it brings.
The 4L60E four-speed transmission is 4 speeds (meaning it has 4 gears). It has 4 gear ratios: 3.06, 1.63, 1:1 and 0.70 (overdrive). Reverse's gear ratio is of 2.29.
It weighs in at 146 lbs without transmission fluid, and 162 lbs with it. GM states that the factory transmission fluid will last for the entire life of the item.
How does the 4L60E TRANSMISSION WORK?
On the roads of many countries, 4L60E transmission isn't a uncommon sight. In 2015, around 34% of the cars worldwide were equipped with one. This is particularly the case in the US in the US, where the auto transmission is very popular.
For a quick overview of how a simple 4L60E transmission is used, if you're not familiar with it, watch this video. Please note that this isn't a specific 4L60E however it can give you a good general overview of how transmissions work. This is an example of the 6-speed transmission, whereas the 4L60E has the 4-speed.
It is the first transmission to utilize electronic shift control. This makes the 4L60E distinct. The 4L60E was controlled hydraulically.
This Wikipedia page provides an exhaustive history of automated transmissions' development through the years, beginning in 1904 and extending to 1923, depending upon the perspective you have.
Why is Electronic Shifting better?
There are very few drawbacks when comparing electronically-controlled transmissions to those controlled by hydraulics or mechanically.
ELECTRONICALLY-CONTROLLED TRANSMISSIONS PROS:
These are the benefits:
Quality of shifting improved.
Shifting is faster
Times for shifting which are more precise
It allows for manual control when necessary.
Fewer mechanical/hydraulic parts and less mechanical and hydraulic components.
Better fuel economy.
More smooth engine performance
Better car control.
Increased life-span of the transmission and its parts along with the driveshaft and engine.
Some might argue that electronically-controlled transmissions can be harder to fix. This is due to the fact that most of the work is done within the ECU, the Engine Control Unit. If there is a problem within the ECU it will require a specialist automotive electrician to get that repaired. This isn't something that most people can fix at home.
