CODE P1744

1997 Ford Taurus

Transmission problem
1997 Ford Taurus 6 cyl Two Wheel Drive Automatic 198k miles

1997 Ford Taurus GL 3.0 U engine / v6
The car has had a slight " miss" (not quite a jerk) running between 40-65 mph.
Sometimes, the car feels like it wants to cut out.
I can get around when driving less than 50 mph, but the car still feels like it's having trouble 'breathing' and there's a feeling of resistance - sorta like - it's running with the parking brake down (it's not, but there's a resistance that feels that way)


The Service Engine Soon (SES) code that came up is p1744. Torque converter clutch code of some sort.

Do I need to focus on replacing one or all of these things?

-- Torque Converter Clutch (TCC) solenoid
-- variable speed sensor
-- EGR backpressure sensor
-- Transmission Range Switch (TRS)



Optional Information:
Year : 1997
Make : Ford
Model: Taurus
Engine: v6 / 3.0 / Single Overhead / U engine
