Clicking Noise When Transmission In Drive 2000 Rx 300

[crownroyal53]

i am not sure what was that clicking noise coming directly from under transmission shift lever housing only when the lever is in drive position. When shift to neutral, noise stops. Although you can still hear the noise in reverse, d1 and d2.but not in neutral or park. it is worth noting that I have recently replaced those vacuum controlled switches from a/c evaporator housing about three switches total. Could someone give me some ideas if you have experienced such annoying clicking-like sound from under your transmission shift lever housing.

I wonder if the shift lockout solenoid is acting up....That is the only thing I can think of in that area.
