can i bench test duty solenoid c?

[rallyingrob]

now that i'm (semi) mobile, i have the 16 blink power light issue....but havent had time yet to run the code(s)

i have the original tranny apart in my shed and i am wondering if i can test it's duty solenoid c for condition?

(yes i am getting an occasional low-speed binding....)

the trans and rear gears in the car now are from a 110,000 mile 98 legacy 2.5 gt wagon....

Pull the codes first. The most common code is the one for duty solenoid "A" or error code 11.

cool
thanks earthworm!!!

Yes, you could rather crudely bench test the solenoid if you take it out. It should not pass pressure when not energised. With voltage applied the valve should open and pass pressure. You can blow on it but must accept the taste. Apply a current for only a short time, as there will be no fluid available which in normal operation forms a cooling medium.

HOWEVER, there will be the risk that the internals are contaminated with grit which may have caused the original problem, to have become only temporarily become dislodged, but to possibly again cause a problem through jamming the armature. It is a sealed unit but could be sluiced out with petrol or whatever.

Only you can decide as to whether the risk involved, is worth the doubtful economy of not replacing the solenoid to be on the safe side, as is normal practice. As you have been very well advised, run a test code as your first option.

You can ohm it out through the connector while still in the car. Details are in the 4eat manual in Lee's locker. I just did mine and found it open. Of course, if it's out of the car already, it's obviously a lot easier. Should be around 12.5 ohms. Here is a highlight:

Code 24 Duty Solenoid C
FWD Fuse & Dropping Resistor Location
1) CHECK SIGNAL VOLTAGE OUTPUT EMITTED FROM TCU.
a. Install spare fuse on FWD connector and set in FWD mode.
b. Turn ignition switch ON (with engine OFF).
c. Move selector lever to "D".
d. Measure voltage output emitted from TCU (with accelerator pedal released).
(Connector) & Terminal(s) Specified value
(B68) No.3 - No. 10 8-14V
e. Turn ignition switch OFF.
f. Remove spare fuse from FWD switch.
g. Turn ignition switch ON (with engine OFF).
h. Move selector lever to "D."
i. Measure voltage output emitted from TCU (with accelerator pedal fully depressed).
(Connector) & Terminal(s) Specified value
(B68) No. 3 - No. 10 0.5 V (max)
2) CHECK HARNESS BETWEEN TCU AND DUTY SOLENOID C.
a. Disconnect connector from TCU.
b. Disconnect connector from transmission.
c. Measure resistance between TCU connector and transmission connector.
(Connector) & Terminal(s) Specified value
(B68) No. 3 - (B14) No. 11 0 ohm
(B68) No. 3 - Body 1 M-ohm min.
(B68) No. 10 - (B14) No. 4 0 ohm
(B68) No. 10 - Body 1 M-ohm min.
3) CHECK DUTY SOLENOID C'S GROUND LINE.
a. Disconnect connector from transmission.
b. Measure resistance between transmission connector receptacle and transmission case.
(Connector) & Terminal(s) Specified value
(T2) No. 4 - Transmission 1 ohm max.
4) CHECK DUTY SOLENOID C.
a. Disconnect connector from transmission.
b. Measure resistance between transmission connector receptacle's terminals.
(Connector) & Terminal(s) Specified value
(T2) No. 11 - No.4 9-15 ohm

BTW- Thanks for having that manual in your locker Lee.

AHA !!!

lol
thanks everyone!!

i will pull codes and test that darn thing asap (likely not til thursday now )

.........dont ya just HATE it when u have to go into work?!?!
lol
