Have you chosen the right way to “rejuvenate” your transmission?

In the automotive service and maintenance industry, the transmission is known as the “brain” of the vehicle, and transmission fluid is its “lifeblood.” As mileage increases, the fluid deteriorates and contaminants accumulate. If not replaced in time, it can lead to rough shifting and increased fuel consumption at best, or complete transmission failure and costly repairs at worst.

What is A Transmission Fluid Changer?

A transmission fluid exchanger, also known as an automatic transmission fluid changer or ATF changer, is a specialized device used to change the transmission fluid in automobiles. It works by using pressure to inject new fluid into the transmission while simultaneously removing the old fluid, creating a cyclical replacement process to thoroughly change the transmission fluid.

Why use specialized equipment to change the oil?

Gravity oil change vs. circulating oil change: What are the differences?

Comparison Item

Gravity Drain Method

Flush Machine Method

Fluid Replacement Rate

Only 50%-60%

Up to 90% or more

Operation Method

Drain plug removal, fluid flows out naturally

Equipment pressurization, dynamic circulation

Time Required

Approximately 30 minutes

1-2 hours

Fluid Volume

About 4-6L

About 8-12L (30%-40% more)

Cost

Lower (approx. 500 yuan)

Higher (approx. 2-3 times more expensive)

Cleaning Effect

Significant old fluid residue, impurities not fully removed

Thorough cleaning of oil passages, cooler, and torque converter

Suitable Vehicles

Low mileage vehicles in good condition

High mileage vehicles, vehicles where optimal maintenance is desired

Simply put: gravity draining is like “emptying a cup”—no matter how thoroughly you pour it out, there’s always residue left at the bottom. Flush machine exchange is like “dialysis”—it filters all the blood and returns it to the body.

Why is the flush machine method more thorough?

Because large amounts of old fluid and metal debris are trapped inside the torque converter, oil cooler, and valve body oil passages—gravity draining simply cannot remove them. The flush machine uses pressure to inject new fluid into the system for circulation, “pushing” the old fluid out from every corner while carrying away contaminants and sludge.

ATF802/805 vs ATF702/705: Complete Analysis of Upgrades

AUTOOL has been deeply involved in the maintenance equipment industry for many years. Building on the widespread market recognition of its ATF702 and ATF705 models, it has launched two new intelligent transmission fluid changers, the ATF802 and ATF805, taking automatic fluid change technology to a new level! We have compiled a comparison table to help you choose the most suitable model for you!

From “Single Pump” to “Dual Pump”—Completely Eliminating Oil Mixing

ATF702/705: Single Pump Design

  1. New and old oils share the same pump and piping
  2. Cross-contamination between new and old oils may occur during oil changes
  3. Manual cleaning of piping is required after each oil change

ATF802/805: Dual Pump Design ✓

  1. New and old oil pumps operate independently, each performing its specific function
  2. New and old oil piping are completely separated, completely eliminating oil mixing
  3. Built-in self-flushing function for one-button cleaning

From “Manual Operation” to “Fully Automatic Intelligent”—Double the Efficiency

ATF702: Semi-Automatic

  1. Cleaning Fluid Dosing: Manual Operation
  2. Circulation Flushing: Manual Control
  3. New Oil Dosing: Manual
  4. Used Oil Recovery: Manual

ATF705/802/805: Fully Automatic Intelligent ✓

  1. Automatic Cleaning Fluid Dosing: The equipment automatically draws the cleaning fluid, requiring no manual intervention.
  2. Automatic Circulation Flushing: One-button start, the equipment automatically completes the entire flushing process.
  3. Automatic Equal Volume Exchange: High-precision sensors monitor in real time, with an error of <0.2kg.
  4. Automatic New Oil Dosing + Used Oil Recovery: Fully Automated Process

From “No Reminder” to “Smart Reminder”—Eliminate Negligence

ATF702/705: No Filter Replacement Reminder

  1. Filter usage status cannot be monitored
  2. Replacement relies entirely on technician experience or scheduled replacements
  3. Filter clogging may affect oil change results

ATF802/805: Filter Replacement Reminder ✓

  1. Built-in operating statistics function
  2. Automatic reminder when filter needs replacement
  3. Ensures optimal filtration results

Customer Value: Never worry about clogged filters causing incomplete oil changes again; the equipment is always in optimal condition!

Q2: Is a dual oil pump really better than a single oil pump?

Yes! With a single oil pump design, some mixing of new and old oil in the lines is unavoidable. Dual oil pumps keep new and old oil in completely separate circuits, eliminating mixing entirely for purer fluid exchange.

Q3: What’s the benefit of automatic cleaning fluid filling?

Traditional equipment requires technicians to manually pour cleaning fluid—it’s not only troublesome but also prone to spills. The ATF802/805 automatically draws cleaning fluid, precisely controlling the amount for a clean, efficient operation.

Q4: Is the filter replacement reminder important?

Very important! When the filter becomes clogged, filtration efficiency drops, and contaminants may re-enter the transmission. The ATF802/805’s smart reminder system ensures the filter always operates at peak performance.

Q5: What’s the purpose of the triple sight glass design?

The ATF805’s triple sight glasses include: an old oil sampling window and new/old oil circulation windows. Before the exchange, draw a small amount of old oil to show customers; during the process, easily compare the color difference between new and old oil. Visible results build customer trust!

Q6: Is a built-in printer really necessary?

For 4S shops and high-end specialized repair centers, absolutely! Printing exchange reports for customers provides proof of service quality and results—not only enhancing your professional image but also reducing potential disputes.

Conclusion

From the ATF702/705 to the ATF802/805, AUTOOL has completed a comprehensive upgrade from “semi-automatic” to “fully automatic intelligent” operation. Core features such as dual oil pumps, automatic cleaning, smart reminders, and data printing make transmission fluid exchange simpler, more precise, and more professional than ever before.

Every AUTOOL transmission fluid exchanger undergoes rigorous testing, ensuring stable quality and worry-free after-sales support.
