Check Torque Converter Lock-Up Clutch Slip
It can be checked with a suitable diagnostic tool.
Road test the vehicle and check live data from input and output shaft speed sensors.
In fourth gear, converter clutch locked, the in and output speeds should be very similar, no more than 50 RPMs difference.
A common issue is a worn valve body causing hydraulic pressure loss.
The lock up solenoid is located on the valve body inside the transmission oil pan.
