I've noticed the last few sub 20 degree days that within the first 10 miles of starting out that if I punch hard on the gas in 3rd or 4th that the clutch is slipping (not during a shift). But after I've run long enough for the heater to make it toasty enough to open the windows, I cannot recreate the slipping...i.e. engine races up with a slow or very little acceleration (no cracks, I've heard all of the slow Scion comments! :twisted: :twisted: ) Anyone else? BTW, I have a stock clutch, CAI, headers, & EVO tail.

this is a common problem for the scions....

it does not happen when you shift, but rather half way up the RPMs...

i would take it to the daeler and tell them...

You shouldn't be putting your foot through the floor until the engine is warmed up. Keep it under 3k for the first couple of miles. If the clutch slipping until it warms up really bothers you, you can go with an aftermarket clutch that has a higher clamping pressure.

the clutch should not slip ever!!!
warm or cold, a yard deep into the throttle or crusing...

keeping it under 3k will not help, and is only your opinion.

going with an aftermarket clutch is an option, but why should you have to on a new car????

Yeah I agree a clutch shouldn't slip. However this is how scion made all of them. What good is it if they change it out with the same clutch. Scion is not going to put in an aftermarket clutch for free.

Besides its not good to rev up your engine until its at operating temp just the same as its not good to let it idle cold for 15 min. Its best to let it warm up 15-30 seconds and be easy on the throttle until its all up to temp.

Every car has its quirks. If you have to drag race your scion with a cold engine and not have the clutch slip then shell out some cash. Otherwise keep it easy a few miles and live with it.

I was considering the TRD clutch before I noticed this. Usually, I'm about 7-8 miles down the road driving around 35-45 MPH up to that point but to get onto US15 REQUIRES maximum power in order not to get killed with the two-way traffic travelling in excess of 70 MPH! People will speed up your a$$ :flame: just for pulling out within their field of view...thus the need to pull off in 3rd or 4th.

toyota's clucth design in these cars is bad the pressure plate is weak or malfuntioning , and my clutch slips under alot of conditions. i have intake , header , full exhaust , this must be whats causing it. but by no means should such small increases in power make a new clutch slip , the pressure plates must be faulty or of a crappy design

Mine does this too, I am not too worried though. Do you guys think that it may damage the clutch or tranny?

yes...

Eventually you scorch the flywheel (for a a real bad ride) and screwup the springs and then you just sit still one day with the engine racing.

too bad if i roll up with intake and header and exhaust theyre not gonna wann do my clutch , back to stock i guess.
