my 06 mustag gt has 57,000 miles 5 speed i hear a clunk after shifting gears am i letting off the clutch to fast? it does kinda jerk slightly .. i am new to driving this car but i was wondering what you guys think is causing the noise ? the driver or is there something wrong with the transmission? ............by the way the parts listed below were on my old mustang this mustang is stock besides flowmasters

Probably the 2 piece driveshaft. If that's the case, an aftermarket driveshaft should fix it.

Nuke

These 2 piece drive shafts (and the entire drive train, to be honest) are clunky to begin with. Add an operator that doesn't have the feel for this driveline and it doesn't help.

You may want to shoot a little grease into the spiders to see if that helps any.

LOL ironically, the sixxers have the better option since it's the one piece shaft.
Earlier ones though (05/06), were prone to failure at the joints.
Always something...

Mine does this if I let off the clutch too quickly or before giving it a bit of gas to hold the rpms steady. Try letting the clutch out a little more slowly or giving it a little gas as you're letting out. An aftermarket driveshaft might help a little, but yeah, as far as I know, you're fine

thanks guys haha yea i started lettin off the clutch slower and it went away. i usually let off as soon as it in gear but hell... i guess thats too much for this car..

It's the two piece driveshaft I thought something was wrong when I first got my gt a little over a year ago. Your fine. I need a solid driveshaft myself, I'll notice a quiet clunking sound when drivin slow.

You might also want to top off the fluid level in the differential.

And chech the driveshaft flange bolts for proper torque.
I had the excessive clunking and it was the driveshaft flange bolts.
Got the proper socket and some blue loctite and re-torqued them to specs.

You're not alone. I have the clunk too. Threw some aftermarket LCAs on and now it's extremely noticeable with the poly bushings...along with every other noise in the drivetrain and rear end. Sloppy drivetrain as others have said before, but love the car so it's worth living with.
