| Transmission Tick Flutter Noise at Highway Speed - 07 & 08 DTS
 This just in from General Motors:
"On some 2007-08 Cadillac DTS vehicles equipped with 4T80E MH1 transmission, a ticking/fluttering noise can be heard in the vehicle at highway speed.
The noise is generated by the modulation of the TCC solenoid. Movement within the solenoid excites the shift cable, resulting in a low level, high frequency noise that can be heard in the passenger compartment
To correct the condition, install a solid lead clamp mass damper to the cable. This has been shown to significantly reduce or eliminate the noise."
If you have this condition, you may want to print this out and bring it to your dealer. |
