It's an Automatic Transmission and I can't figure it out what's the problem on tester I Only have Auxiliary water pump on insta/inpa.
I have checked and replaced all Vacuum lines for leaks.
These symptoms I only Have when the engine gets hot, at the first key is acting normally.
What I guess is the torque converter so I'm uploading this video to be sure in finding the problem so What do you think?
