Yea trans fluid was changed at time I got the truck I have since put 4k on it trans is all stock to and knock on wood still shifts good and don't slip

That's it I'm doing injectors soon any idea what the injector torque spec I see some say 60 and 89 inch lbs

Any small leaks in the intake system?

89 in-lbs sounds correct.

Check valve lash and have injectors tested to confirm size
