I have a 2003 ford mustang gt stick shift. clutch sliping

With out any other info. like ... did some one replace clutch and pressure plate??, if so ,did they put the correct side of disc plate to flywheel (there is a diff.), did they machine the flywheel surface???, did they replace pilot bush/bearing, throw bearing??? did the clutch get adjusted right (if adjustable) how many mill's before it burns up etc...etc...last i have to offer for >>>excessive clutch disc burning>>> i suggest you keep foot "off" clutch peddle until your going to shift learn how to drive a stick shift correctly , the little cars we have today only have a very small clutch disc in them and they don't tolerate much abuse before they burn up from "slipping" , good luck !!! <:0}

Sounds like the interlock is out of adjustment. There is a switch on the brake pedal lever which sends a signal to release the shifter by reading the brake light signal. Often this switch gets hit by the Drivers feet and has either moved or broken. Your shifter will act up if the Ignition switch rod has slipped out of adjustment or if the ignition switch has slipped on its mount on the steering column.

Sorry old son but your clutch sounds like it has gone to the big junk yard in the sky reserved for dead clutches . When a clutch starts to slip it will continue to do so until that is all it will do . solution a new clutch is required .

sound like u need a new belt. its slipping or a pulley is bad

Automatic or stick ?
If its an automatic, it could be something in the torque converter or transmission. The torque converter clutch could be stuck.

Sounds like the clutch could be going, or the transmission has been beaten on an is getting bad. Try a new clutch first.

if clutch not slipping, problem is in the shift linkage or cable could be damaged or need adjusting.

the transmission is fine its the springs in the preasure plate that have shrunk and the clutch needs to be replaced.
I hope this advice helps.
can u rate the advice please

you know some mustangs have an adjustment system on the clutch pedal, and might need adjustment, or if you install a rebuilt clutch instead of a new one some times they come unbalance and vibrate if you did just never again trust a rebuilt clutch kit
