Hello. I drive a Mitsubishi Spacegear (gas, 2003) and I have been having problem with its overdrive. When OD is on, I hear a loud clicking sound behind the glove box. No pattern at all, it's very random. Sometimes it's not there, sometimes the clicks are in short bursts, sometimes far and few in between and there are times that the clicks will be rapid and non-stop, to the point that the car will be confused and will keep on shifting gears. When this happens, I just turn the overdrive off.

Has anyone had the same problem with overdrive? May I ask for some advice/recommendations? Thanks in advance!
