1982 Oldsmobile Toronado with the TH325-4l. Computer deleted. Installing a vacuum switch to operate the lock up solnoid since the previous owner did not. The fluid was clean with no metal shavings or much friction material. Problem. It drives fine in first, second, and reverse. Slips in 3rd, and 4th. Won't engage or go anywhere in 3rd or 4th. Is this a torque converter problem because of the lock up? Could the clutch in the converter be toast from being constantly locked up and abused by the previous owner. Just bought the car and sorting things out. I understand there is no band adjustment possible on these so if it's a band then I'm gonna have to rebuild. Should I try the vacuum switch first and hope for the best? 3 wires on the square plug which one do I put the 12v switched power to? I will be rebuilding the transmission in the near future as it's not beyond my skill level. I'd just like to keep it going until I have time for a full rebuild. Also what is a good torque converter for replacement? Thank you.
