SOURCE: after 45 minutes of driving my transmission changes rough

These transmissions were known for having PCS(Pressure Control Solenoid) problems with the higher miles I would agree on a complete trans flush and filter change.The Pressure control solenoid sarts to hangup causing high pressure when not commanded which will cause hard shifts.

SOURCE: 2003 chevy impala ls starts then stalls

I have replaced the radiator in my 2003 Chevrolet Impala LS. The car started running hot and shut down. Took it to a radiator shop and found a crack in the radiator. I have replaced 2 thermostats in the car already. I noticed water running from under my car today and it seems it was coming back out of the overflow. I am stumped as to what is going on with this car.

Why does my car have trouble switching gears?


P0730 is your problem code for incorrect gear ratio, this is usually due to a bad clutch pack in the transmission, meaning it needs rebuilt or get a remanufactured one.

Car wont start seems to be a security code that has prevented the car from starting whats youe dignosis its a 2003 chevy impala


Call a Chevy dealership, ask for service department. Tell them about it and ask what you have to do to get the code. Also if it is n9ot a code then they may be able to help you out by giving you some suggestions, other than bringing it in to them.

My 97 Saturn SL2 won't go past 30 mph. Even with


I guess my first question would be - are you saying it is slipping in 3rd gear ? If you push the gas pedal to the floor it should downshift into a lower gear.
If it is slipping, or not upshifting into 3rd gear, I'm afraid chances are the transmission is toast.
You can take it to a couple of shops for estimates but they will probably want to pull the pan and take a look inside.

"2003 Chevy Impala won't start". Car would not


The alternator is not charging,or the battery wont take a charge.If all accessories work fine when its running after you've boosted it,its likely the battery.

My drivers heated seat is not working in my 2003 chevy impala and it also shifts hard.


1.)heated seat is usually the heating elements under the seat cover.
2.)shifting is likely a pc solenoid and valve body.CODE associated with this is a p1811.If your vehicle has high miles or there is alot of debris in the pan of the trans,then I would suggest a reman trans.

I have 58 chevy apache and have a turbo 400 transmission. It does 60 mph at 3000 rpm's. I would like to change the entire rear end so that it goes 60 mph at approx 2200 rpm. I now have a 350 engine in...


I don't think you can get a rear end that high sped, the best I've ever seen is a 3.2 something . I had that with a 305 and my engine revved higher than 2200 with that. I think you would be better off with a 700R4 transmission from the early-mid 80's. It should bolt on and the overdrive works off an electric/vaccuum switch mounted on the firewall. Hope this helps.

Have a chevy impala 2000 with 3800 in it. the tranny has been shifting hard off the stop. If you gradually depress gas pedal then there is no problem with shifting in any gears, but when yor at a stop, and...


You seem to be on the right track. You should replace the PWM solinoid also, that is the most likly cause for the conern. Make sure the valves move good also, high milage may end up needing a valve body due to sticking valves.
Make sure to check your mounts also, that could be the banging you feel.
Also there should be a code in the pcm if it is banging as hard as you say, p1811 is the most common, but that usally has a shudder also.
