As the title says. But it's not a firebird or camaro. Oddly enough though it is a 3rd gen. It's an 02 eclipse sypder with a 2.4. It's a commuter and something to drive while the ole TA is down. So I had to replace the radiator and now this is happening. When I bring the car to a stop it will almost do a little jump like it's switching gears more then once. On the radiator are the two hoses that cool the trans fluid just like our automatic cars. A very little trans fluid leaked out when I changed the radiator. Would low trans fluid cause this symptom or not? If not the what would? and the only reason I am coming here is because people at the 3rd gen eclipse site aren't responding. And yes I know an 02 eclipse spyder with a 4 cyl is a chick car but like I said its a commuter while the TA is down and gas prices are so ridiculously high.
