According to my electrical schematic, the tranmission in the 1997 has two
shift solenoids, one torque converter clutch solenoid, and one pressure
control solenoid, but the 1998 has three shift solenoids, one torque
converter clutch solenoid, and two pressure control solenoids.
It's been awhile since I've looked at one of these electrically, but I'm
curious how you even got the electrical connectors to plug in.
How many terminal holes do you have in the shift solenoid connector on the
harness and how many on the trans connector?
