D5 to Reverse Audible Knock/Thud

I tried to search, but am not finding anything similar to what I'm experiencing. Shifting from D5 to Reverse, I'm hearing an audible knock. It's just a singular knock that sounds almost like a pop. Everything is operating as it should. All gears work just fine. Doesn't make the noise from neutral to reverse, or park to reverse. Flat surface, brake supressed.

Could this be a tranny or engine mount possibly?

How fast are you driving when you go from D5 to reverse?


Check for low tranny fluid also. That can cause a thump.

almost willing to bet it's the rear mount.
My other car has a bad front mount and when going from p to r it bangs.
so going the other way with your bang ,I would check the rear.
To check have someone look under the hood for excessive motor movement while your making the noise.
It will be easy to see if it's a bad mount.

Thanks for the input guys. I'm pretty sure it's a mount. Aren't the rear mounts a serious pain in the ass?

so for replacement mounts, do I go OEM or are there upgraded mounts that are more cost effective and better?

if I were you i'd go oem.. I replaced 2 of the 3 with oems and just have the rear one left to do.

OEM mounts will get rid of vibrations when u mod the oem mounts (fill them with polyurethane) or but aftermarket ones.

I've heard way too many problems also with the manufacturing of the aftermarket mounts and all that just made m,e say... to hell with it and stick with oem

Im running poly-filled OEM mounts and I love them. Yes, they do increase vibrations, but they decrease wheel hop, so Im happy.

And $600 for 2 mounts is friggin insane.

The front and side mount was the easiest for me. I think it took me about 4 hours with basic hand tools.

The side mount was laughable, it took maybe 30 minutes.

The front was a bit of a bitch. The mount bracket is hard to remove, and the bolts on the subframe were seized.

Its not nearly as bad as the rear mount though. I did the other 4 one day then went back for the rear. It took me nearly 6 hours because the damn thing wouldnt line back up.

You have to get underneath the car near the drivers side tire. You'll see them.
