What's that Clunk?


DashingDaryl

Recommended Posts

My Mom's 1995 4.9 Deville has a clunk whenever the car shifts gears. The car's battery was giving us problem, but we got it resolved. I still haven't done the idle learn procedure on it and wonder if that isn't part of the problem

Do you think the hard shifts are due to the battery, the Idle Learn Procedure, or a bad transmission mount?

The car is 10 years old, and the mounts have never been changed.

I see there are two tranny mounts and one engine mount.

Do you think it's a Tranny mount? And DOES ANYONE HAVE ANY SECRETS/SUGGESTIONS ON HOW TO CHANGE THEM? Is it pretty straight forward?

Open the hood, perform the power brake maneuver (brakes applied firmly shift in D and R) and watch the engine. If it jumps more than 0.5" mount/mounts are bad. The mounts are more visible when the same procedure is preformed on a hoist.

So i got both of the tranny mounts from the dealer. I crawl under my car, and one of the mounts looks smaller. It's the right mount, (number 10 in the picture) and it looks like the "Legs" of the mount are significantly smaller on my car.

I run the part number through trademotion, and it says there is only 1 model for the right side mount for all 4.9 engines, so this must be the one.

Has anyone else ever had this problem?

Your Deville should have 2 dogbones, as does my 96 unless your year differs.

Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life.

A lot of OEM online parts places use a program that they rent from TradeMotion. It has a listing of all the parts for your car (or most of them) It is an electronic version of the Insurance Books they use to quote accident damage.

If you go to someplace like Autopartspeople.com you can look up the part you need, and view the illustration, if it has one.

another interesting places to go is www.acdelco.com which allows you to put in a ac delco part number and find out what vehicles the part will work for.

I think they are called torque strut mounts, as you rev the engine you will see them limit the engines movement, I am sure they do quite a bit under acceleration to stop engine movement. I am not 100% positive but I think they may sell replacement bushings for that mount, Mike

You assume correctly!

I don't know about replacing the bushings in the dog bone but when I replaced the dog bones on my w bodies before, they were only like $15 a strut. I can't imagine trying to replace the bushings in one of those just to save a few bucks.
