2008 Scion tC Repair Question

2008 Scion tC problem accelerating
Engine Performance problem
2008 Scion tC 4 cyl Front Wheel Drive Manual 39000 miles
After i shift into gear i go to accelerate and the rpms will go to just about redline and the car will not accelerate with it. If i keep on pressing the gas while this is happening it will eventually catch up to itself and be fine. But if i release the gas while the rpms are increasing and then press it again when the rpms lower the car will accelerate fine. Please help me try and figure out what the problem is because i did bring it to a mechanic and they said it was the clutch but i dont see how.

Hi nicor5390,
Thank you for the donation.
If the clutch is failing, it would slip. During gradual acceleration, there is sufficient grip to get the required torque to move the vehicle.
Hard acceleration would result in slipping as the clutch is not able to get the requuired grip onto the flywheel to provide the torque necessary to move the vehicle. If the process is repeated for extended periods, the clutch would start to smell like something burning.
After vehicle is moving, depress the clutch and race the engine to 4000 rpm, quickly release the clutch in 4th gear. If the clutch takes a long time to catch, it is bad.
