Yep it's not reading the TCU at all even after trying to erase the code it pops right back up.
maby the TCU crapped out, go steal Brandon's for a min :dunno:
I might have missed it but what year
Make sure the ignition is OFF!!
An easy way to test for power and ground is to pull the connector off the TCU (on your 1998 it is located on the transmission tunnel just above and toward you from the gas pedal). The connector has three fat pins on one side and two on the other, with smaller pins in between. Holding the connector so the three fat pins are on the right, probe the second pin from the right on the bottom row -- it should show battery voltage. Be careful, you don't want to short this pin to anything else!
Now set your meter to ohms and probe each of the three fat pins on the top row. Each should show about 13 ohms resistance -- if they show significantly more and all are the same, you have a bad ground. If only one or two shows excessive resistance, the individual solenoids are bad or have poor connections.
Bad connections can occur within the transmission, the connector at the transmission, the connector right next to the transmission oil dip stick, or in the wiring harness itself.
The approach I would take if it isn't a bad ground (all solenoids show high resistance) or lack of battery voltage is to probe the connector next to the transmission oil dipstick. If it shows the same excessive resistance then I would probe at the connector at the transmission.
Report back what you find and we will help you focus on the trouble spot.
id say the solenoid was stuck with the fluid looking like it did.. have you figured out how to test them? ill look and see if I can find. 97 right?
