I had the splash guard off because it is busted .. and taking it off has revealed a cyclical ''whirring/whining noise'' on deceleration only in third gear.
it pulses rapidly in PITCH, and it correlates to vehicle speed, slower speed = less swings in volume and pitch, faster = more volume and pitch
going up a gear stops the noise
going down a gear stops the noise
going to neutral stops the noise
the trans shifts fine between gears in manual mode and auto mode .. no hesitation or slow shifts
I assume it is NOT a solenoid.. but in the off chance anyone has heard this noise i thought id reach out and see what everyone says .. TY in advance.
