Bypass Feature

The T-TECH bypass feature allows new ATF to loop within the vehicle

when the exchange is complete and the piston is at the top of the

cylinder. This feature allows the operator to walk away (work on

something else, etc.) when the machine is running, without being

concerned about service completion. When the piston reaches the top

of the cylinder (old ATF has displaced all of the new ATF), the bypass

feature is automatically engaged. This causes the new fluid to be forced

into a loop through the vehicle and the

T-TECH unit. The bypass will

continue until stopped when the operator turns the vehicle OFF.

Replace Existing New ATF with Different

New ATF

Use this procedure to replace a new fluid type that is already in the

cylinder with another type of new fluid needed to perform a current

service (e.g. the cylinder is currently filled with DEXRON III but you need

to service a Chrysler that uses MOPAR+ fluid).

To accomplish this task, the piston will be pushed to the top of the

cylinder to force any existing new ATF into a clean storage container so the fluid can be reused. See Figure 61.

1. Set CONTROL VALVE to SERVICE VEHICLE.

2. Attach a service hose adapter to each service transfer hose.

3. Insert one service hose adapter into a clean container to save the fluid that is to be removed from the

cylinder.

4. Insert your air nozzle into the open end of the other service hose adapter.

5. Apply air pressure (air pressure should be above 10 psi but should not exceed 20 psi on the system

pressure gauge).

6. The machine will sense the pressure and the piston should begin to rise. As the piston nears the top of the

cylinder, ease back on the air pressure.

7. When the piston reaches the top of the cylinder,

hold the air nozzle and service hose adapter in a

waste container with the service adapter pointing

away from any personnel. Pressurized air and

possibly some ATF will be expelled out of the end

of the service hose adapter when the air is

released and the line hose is removed.

8. Release the air pressure and remove the nozzle

from the service hose adapter.

9. Refill the cylinder with new ATF fluid of the type

required to perform the service according to FILL

CYLINDER FUNCTION. Make sure to fill the

cylinder until the cylinder is completely full of ATF

to avoid any air pockets under the piston.
