Hi All,
HELP!! I'm desperate !! ;o)
I have the Valve Body out of the Trans
and I'm ready to Test the Solenoid
If I can just figure out how to safely !! :eek:)
As far as I can figure out,
I need to power it up with 12 volts
with a 1amp fuse in the + line.
iF anyone knows for sure, I could really use the assistance ! ;o)
Here's a picture of it:

Hi All,
New member here.
I am pulling a P0707 code on my early 2003 Corolla.
I have read a lot of posts here on this code, but i haven't found a definitive one on testing the Solenoids.
I have read 12 volts straight off of a car battery,
9 volts off of one of the small, square 9v batteries and also,
12 volts with a headlight and fuse in line with the probes.

This all started, because I wanted to get to know my Corolla a little better and to be able to do my own maintenance as much as possible.
So,,, I changed my own Transmission Fluid.
Problem was I didn't read the instructions on the gasket/filter(screen) package
and I used RTV sealant which dissolved into my tranny fluid and as far as I can guess,
( unless caused by a different coincidental problem )
set off my CEL light.
Auto Zone says it's a P0770 Transmission Solenoid Code.

Has anyone Here Tested these Solenoids?
My worry is testing them without burning them out!
How does Toyota do it?

If I understand correctly, there are 4 solenoids in the bottom side of the Trans.
And One Overdrive locking Solenoid on the Top?

What is the correct procedure?

Thanks so much in advance for your help !!!

best,
Jonathan
