My 2000' Plymouth Voyager is acting up. The transmission shifts ok pretty much, but when it gets to 3rd gear (This is a base model with the 3 speed and has no overdrive) it sticks. Like when it hits 3rd and then i go to stop it stays in 3rd and causes my car to shudder and stall... I can put in neutral or turn the car off and back on and back into drive and its just fine untill i hit 3rd again.... Any ideas?
