Last night my 2007 caliber R/T broke down. I was on the interstate when it started making a clinking noise, followed by whining. Shortly after that the RPM's began going wild and my car wouldn't accelerate. I slowed down and pulled over and then tried to put it in drive, to which it whined and wouldn't move. It then went in reverse perfectly fine with no noise. It's throwing two codes- p0746 and p0777 which appear to be two solenoids and a possible slipped belt? I'm assuming I'll need a new transmission? Or am I wrong and this is a problem that's a little less expensive to fix?

 

Difficult to diagnose over the Internet. I suggest you take it to the dealer or a transmission shop for a proper diagnosis.

 

From what I have read, I think they are disposable transmission, or at least they used to be.
