Clunking /rattle noise

**xenergyx** · 11-02-2014, 05:41 PM

Okay I had a lil trouble labeling this topic....I have an 02 trans am ws6 with a 4l60e trans I have just completed changing the fluid in it as well as changing the filter. After I was done I let it idle and warm up and than cycled each through the gears at idle each for a few mins and than took it for a test drive everything was fine. Later in the evening I took it out for a longer ride as I was waiting in a drive thru I heard a faint metallic clunking/rattling but its only really audible in the car in park and neutral. Does anyone know what this might be ?

Check your engine and transmission mounts.

I assume you checked the fluid level after the change? With the transmission up to temp, the engine running and and the car parked on a level surface, slowly cycle through each gear and then once back in park pull the dipstick to check the level.

Yes i checked the fluid after it was up to temp and cycle each gear for abt 2 mins....and the trans mount has been replaced once i did check it before i took the car off the stands it was still in good condition....any other ideas .....if its a cracked flexplate how can i inspect it without taking it out of the car?

Your best access to the flexplate is to pull the starter. You can then roll the engine over using a breaker bar and a socket on the balancer bolt. If it turns out you do need a flexplate, I have our stock one setting in my lower garage awaiting a new home.

Any chance you bumped the exhaust while working on the transmission and moved something?

I think it might be that catalytic converter on the pass side so i plan to take it off and check inside it after it cools down in an hour or so....and the only reason is cause i found a video where someone had the same sound...*crossing fingers*
