Hello I have a 700R4 behind my 341 DeSoto hemi. I have the Bow Tie Overdrives TV cable kit and it is set as firm as it will go. When I am driving under light throttle(highway cruising), and idiling there is a gear drive noise coming from the tranny.
The line pressure is about 85 psi at idle. It is pretty annoying, and I was wondering if this is normal, or it is indicative of a problem. Could anyone shed some light on this problem?
