Question about 2001 Lincoln Continental
P1774 - Link Gear Shift Module / TCM
This means the computer has detected a slippiage. First thing you can do is a transmission pressure test, it should be 62-81 psi while in park or drive and 110-120psi while in revese. If pressure is low the problem could be the pump, a external or internal leak, pressure regulator valve, or epc soenoid/circuit. Otherwise you could start by replacing the EPC solenoid and the pressure regulator valve. If that does not fix the problem you would probably want to bring the vehicle into a transmission shop to have them diagnose the problem.
The EPC solednoid is the most common cause of this from what I'm aware but the torque converter itself could be the problem also but you would want to have every other possible cause checked before replacing the converter since that is expensive and time consuming.
Hope this helps (remember to rate this).
