To all chevy impala owners, the problem with the impala transmissions are that they tend to get overworked due to axle parts disagreeing with the power from the engine which overworks the trans which is the biggest problem with powerful front wheel drive vehicles. i installed a transcooler which prolongs the right viscosity of your transmission fluid which boosts the transmission life considerably especially if you drive in the city or under rough conditions. Maximizing the cooling of your powertrain maximizes the life of your parts and minimizes your stress. Also for the ones that have been driving on it for so long and not tending to the problems of your trans you may have to have the pump in the transmission replaced which then is about 800+ depending on the shop . Another tip is to have your transmission fluid flushed every 50-75,000 miles as opposed to 100-150,000 miles, when transmissions are overworked they tarnish and burn the transmission fluid in which flushing the transmission is also a beautiful thing

i've did my homework on these cars and the tranny is a big problem. this is my second tranny and i noticed the hard shifting (it's been in about 6mths), so the only thing i could think of was drive it till it goes out then back to to the $1,000 odd dollars i had to spend and replace it again. well my check engine light came on today and i took it to advance auto parts they said o2 sensor. i removed the upper o2 sensor and drove back to advance (with o2 sensor out) because i thought they gave me the wrong one. guess what i noticed? i had a bad exhaust leak because the sensor was not in and my transmission shifted like a brand new car. which leads me to believe all these trannies are going out because of a faulty exhaust system. either the catalytic converter or the muffler's are faulty and not allowing the motor to breathe correctly. my next step is bypass the converter and see what happens. hopefully this will help out alot of people and Chevy company to regain peoples faith in them. if anyone get a chance remove the o2 sensor and let me know if shifting change for you.
