Abstract
A method and apparatus for flushing an automatic transmission cooling system. A sealed pressurized canister having an outlet and no inlet and a biodegradable soap solution thereinside is coupled to the cooling system, and a valve releases the soap within the canister through the cooling system. A tube within the canister extends from the canister's outlet into the soap solution, and after the soap is expelled from the canister, the canister is inverted and pressurized air from the canister purges the soap solution from the cooling system. A bag may be provided to catch the waste soap solution emerging from the cooling system.
Claims13
An apparatus for flushing an automatic transmission cooling system having a first port and a second port and including a fine metal weave therein through which hydraulic fluid flows, said apparatus comprising:
- (a) a disposable sealed pressurized canister having an outlet and no inlet, said canister having a soap solution therein and being internally pressurized substantially above atmospheric pressure;
- (b) coupling means including a hydraulic coupling adapted for sealingly connecting said outlet to the first port of the automatic transmission cooling system;
- and
- (c) valve means for selectively placing said coupling means in communication with the interior of said canister.
In combination:
- an automatic transmission cooling system having a first port and a second port and including a fine metal weave therein through which hydraulic fluid flows;
- and an apparatus for flushing said automatic transmission cooling system, said apparatus comprising:
- (a) a disposable sealed pressurized canister having an outlet and no inlet, said canister having a soap solution therein and being internally pressurized substantially above atmospheric pressure;
- (b) coupling means including a threaded hydraulic coupling for sealingly connecting said outlet to said first port;
- and
- (c) valve means for selectively placing said coupling means in communication with the interior of said canister.
