^
Residual solvent contamination can cause damage to friction bonding materials within the transmission (Clutches and Bands).
^
Lack of fluid heating and agitation prevents this method from completely removing contamination from lines, in-radiator coolers and auxiliary
coolers.
Aerosol Solvents should never be used for several reasons.
^
They do not provide the volume necessary to remove heavy contaminants.
^
They evaporate quickly and essentially leave contaminants in pockets, bends, or wherever they are as the solvent dries.
NOTE
YOU MUST IDENTIFY THE RETURN COOLER LINE TO START THE BACK FLUSHING PROCEDURE.
A quick way to identify the return cooler line (fluid coming out of the cooler and returning to the transmission) is to locate the return cooler line fitting
on the transmission case. Refer to the following lists:
Rear Wheel Drive
^
TORQSHIFT, 4R100, E40D, C6 - The REAR transmission case filling receives the return line.
^
4R70W, AODE, AOD - The TOP transmission case filling receives the return line.
^
A4LD, 4R44/55E, 5R55E, 5R55N, 5R55W, 5R55S
-
The TOP transmission case filling receives the return line.
Front Wheel Drive
^
CD4E - The REAR or Pump End transaxle case fitting receives the return line.
^
4F27E - The REAR or Cover End transaxle case fitting receives the return line.
^
AXOD, AXODE, AX4S, AX4N, 4F50N - The BOTTOM transaxle cooler line fitting receives the return line.
NOTE
IF AN IN-LINE FILTER HAS BEEN INSTALLED IN THE COOLER LINE, IT MUST BE REMOVED BEFORE FLUSHING THE COOLER
OR COOLER LINES.

Located on the "Turbo-Tank Heated Cooler Line Flusher" is a fluid transfer and purge valve. This valve can be used to purge the cooler and cooler lines
of contaminated fluid before starting the back flush procedure of the fluid cooling system (refer to step 5a of this Service Procedure or Equipment
instructions, supplied with the "Turbo-Tank Heated Cooler Line Flusher").
Flush Procedure
1.
Check and top off fluid level of the "Turbo-Tank Heated Cooler Line Flusher" tank with transmission fluid.
2.
Allow the fluid in the flusher 15-30 minutes to heat up to 140° F (60° C) before using.
3.
Install line adapters into the transmission cooler lines.
4.
Attach the flusher's blue line to the transmission return cooler line quick disconnect.
5.
Attach the flusher's red line to the transmission outlet cooler line quick disconnect.
a.
Follow equipment instructions, to purge cooler lines and cooler prior to starting flushing procedure (using factory installed purge valve and
clear hose on "Turbo-Tank Heated Cooler Line Flusher").
6.
Allow the cooling system to back-flush for 10-15 minutes, then flush the cooler in a forward/normal flow direction for an additional 10-15
minutes.
