Intermittently when accelerating normally from a stop. Once rolling it doesnt happen. Has anyone experienced this? I had a torque converter & shift kit installed in the spring. August I had a cam & headers installed. This loud pop sound started a couple weeks ago. A local shop said it was the trans slipping & that every auto does it & its normal. Im worried. Any ideas?

Thanks

 

get ur rear end checked sounds like it may be that! Just go to a shop and they can tell you for sure, good luck!

 

Thanks. What do you think causes the popping sound?

 

Look at your transmission mount and torque arm bushing, check for any wear or tears...replace them if they are torn. Also, check you suspension in the rear, make sure everything is up to par.

 

Check your transmission mount and torque arm bushing, replace them if they are torn. Then check your rear end.

 

If the transmission mounts check out next stop is the rear end. Is it still stock, rebuilt ect?

 

this happens in both my buddies cars, when they get it over 3k it pops, it was the tranny mount. Its just a bushing on the outside fot he tranny that keeps the tranny from slamming against the body, so obviously when it is broken its banging the bejesus out of the car. .02

 

As you can see in my sig I have a converter. The rear is stock & only 19k on the car which has been driven with care always. I do not drive the car hard usually. The popping is intermittent but when it happens its always from a stop & after ANY type of acceleration. Usually I accelerate slowly. Sometimes it happens all day & sometimes not at all. Today it happened a couple times while driving then it didnt happen any more. I cannot find the exact conditions that makes it happen. It definitely sounds like its coming from the rear though.

 

If it's coming from your rear, it could be your diff.

 

Due to the fact that you have a stall now and a shift kit I'd say your stock torque arm (I'm assuming it's stock) is getting hit much harder now. That stock torque arm is a piece of crap. Lose it and get an aftermarket one. I got the BMR tranny mount (adjustable) and the popping went away and never came back. I would try that before digging into your differential...just my .02

 

Does the pop feel like its coming from the chassis? Like something hitting?

btw the message mailbox is full.

 

If it's coming from the rear of the car, check the lower control arm bolts. I had a pop and that's what it turned out to be. The bolts had looseened up a hair.

 

Ditto. Probably nothing mechanical unless it's in the rear end itself. Could be bushing issues on your trans/torque arm/lower control arms.
