What is the difference between CVT, ATF, and ATF+4?
Automatic transmission fluid (ATF) is a type of transmission fluid utilized in vehicles with self-shifting or automatic transmissions. It is typically colored red or green to recognize it from motor oil and other fluids in the vehicle.
The fluid is optimized for the specific qualifications of a transmission, such as a valve operation, brake band friction, and the torque converter, as well as gear lubrication.
ATF is also utilized as a hydraulic fluid in some power-assisted steering systems, as grease in some 4WD transfer cases, and some modern manual transmissions.
Firstly, we require to understand what is ATF and CVT transmission systems. ATF stands for (Automatic Transmission Fluid). An automatic transmission, also named auto, self-shifting transmission, or AT, this system utilizes the fluid coupling in a position of a friction clutch, and performs gear shifts by hydraulically securing and unlocking a system of traveling gears.
These systems have a determined set of gear ranges, frequently with a parking pawl that secures the output shaft of the transmission to prevent the vehicle from rolling either ahead or behind. There are several collections of gear, Auto Transmission fluid is very essential in this system, to present a lot of grease cation and decrease as much fiction as possible when the vehicle is moving.
The ATF+4 fluid is formed of a Texaco-produced Extra High Viscosity Index (XHVI) Group 3 base oil plus an additive package produced by Lubrizol. This fluid exceeds and survives the previous ATF+3 fluid Material Standard and was first utilized in some Chrysler mini-van transmissions in November of 1999. This fluid is granted a “Fill for Life” fluid by Chrysler. Do not confuse this fluid with Toyota‘s Type T-IV, they are not interchangeable.
The ATF+4 Type MS-9602 Fluid Material Standard was acquired in 2003 (MS-6902 Change C) for the newly developed 6-speed transmissions. This fluid is compatible with the earlier ATF+, ATF+2, and ATF+3 fluids, but not compatible with Dexron fluids. This was Chrysler’s first “Lifetime” fluid with no fluid or filter adjustments needed under “Normal” driving conditions.
Difference Between CVT, ATF, and ATF+4:
ATF +4 is a synthetic fluid for finely-tuned transmissions, so if you use a non-synthetic ATF rather than ATF +4 in a car or truck that calls for it, you could break the transmission. You may use ATF +4 in most applications that call for older Dexron and Mercon fluids.
CVT and ATF:
Most souls don’t understand what is different between these 2 types of fluids for CVT and ATF transmission. What if they put the wrong fluid in their transmission system, it will a huge mistake.
In order not to put the wrong fluid, we require to know the 2 kinds of fluids first. They work differently in features.
The CVT stands for (Continuously Variable transmission), also recognized as a single-speed transmission, steeples transmission, or pulley transmission. Also, the CVT system doesn’t have a collection of gears to push the vehicle. So, the CVT can shift seamlessly through a continuous series of powerful gear ratios. The versatility of a CVT provides the input shaft to keep a steady angular velocity.
A belt-driven design was in the CVT system. There are 2 kinds of belts, a belt or a metal chain belt. The only thing that performs the variety for CVT fluid is that the fluid has to create more fiction rather than less fiction. It is because it’d run on a pulley system running by belts, it has to be grease cation with more fiction to prevent the belt from sliding on the pulley system.
