I got the same problem with the transmission control! Thanks for sharing , excellent explanation of what is going on with my system

Awesome video!! Thanks for sharing your diagnostic procedure for the TCC. Thank you.

I just wish all manufactures would allow TCC lockup control with a scan tool. Many of the newer vehicles do not have any solenoid testing.

👋 My son has a 2000 Cadillac Deville and throws P0741 & P1860 codes. P1860 says TCC PWM Solenoid Circuit Electrical Any advice is greatly appreciated!!! BY the way the car has only 57K miles

How do you check to see if a PCS pressure control solenoid is bad?

[@ThePracticalMechanic]

The pressure control solenoids are more difficult to test because the pintle hump isn’t visible on most vehicles. The TCM operates the pcs solenoid with a duty cycle keeping the valve open slightly all of the time. Sometimes you have to disconnect the TCM and manually power the solenoid briefly and check the scope pattern.
