Default Transmission Clank

So I noticed something that is odd but what I always figured to be normal. I got to thinking and wondered if anyone has similar experience? My 2002 only has 27k miles so I'm hoping it's nothing out of the ordinary. I understand that the transmission will make some noise in shifting but I'm noticed a pretty solid "clank" when I shift especially from Park to Drive or Park to Reverse. Just wondering if other drivers have a similar experience? I remember my last car had a sort of "ratchet" sound in shifting and I've grown accustomed to this "clank" now, but just wondering of others have the same clank? If not normal, what should I look into? Also before it's recommended, I know it's not the brake caliper clips as the "clank" occurs before actual vehicle movement. Thanks in advance.

My guess would be the transmission mount.

Hey,,

do you use the foot brake? when stopping/parking

i find my transmission makes a clunk when i dont press the foot brake before i let go of the actual brake, which stops the car on a gear and when shifting out it makes a sound.. Specially on a slope it can louder then normal. My GX does same.. its best to use the parking/foot/hand brake, dont let it roll back and stop on the gear.. let me know if that seems to be the issue

The motor and trans mounts are very soft on these cars.
I had a trans clunk on my SC400 and replacing the mount solved the problem.

hmm i have heard of the engine mount issue but not the transmission mount and i wouldnt be surprised if the mounts are bad anyways lol, all rubber mounts, bushings crap out really fast on this car... But ya the feeling i get is if i park on a slight slope, and not use the foot brake.. the car slightly moves back and stop on the gear.. Now when i try to shift out, its very slightly harder and thats when i hear a clunk type sound... it feels more in the transmission itself then outside... but stopping the car on footbrake solves that for me.. Its why i was wondering if ShawnOk experiences that..
