Operation Check

Solenoid Valves (Shift Solenoid Valves and TCC Solenoid Valve) Operation Check
Whenever shift solenoid valves and TCC (lock-up) solenoid valve are removed from transmission, verify their valve function physically before they are reinstalled.
1) Apply oiler (1) to solenoid valve (2) and give compression by hands and then check to be sure that transmission fluid from oiler (1) does not come out of holes (4) in solenoid valve (2) when battery (3) voltage is not conducted.





2) Under the same conditions as above, conduct battery (3) voltage and then make sure that fluid comes out with vigor.

NOTE:
^ If fluid does not come out with vigor in above Step 2), do not re-use that solenoid valve (2).
^ Figure shows shift solenoid valve (2) check. Check TCC solenoid valve also in the same way.
