Automatic Transmission Problems

[vash.t.s.]

I recently had to replace my radiator, ever since my car has been acting funny. My car will shift hard from 1st to 2nd, not really noticable in any other gears but since then i havent tried driving my car on the freeway. When i floor my car it accelerates really slow as well. Another odd thing when i turn on my car the O/D light will flicker for about 8 seconds. I dont know what to do. if anybody has any insight let me know. and another thing my idle is dangerously low below 500 after the car warms up.

When you replaced the raidiator, how much transmission fluid did you lose? Did you check after while the car is running and fill up the car to proper transmission fluid level?

not that much, but there might of been more in the radiator

your problem may be similar to his:

hopefully the old trans fluid isn't burnt/milkshake-looking...

recheck the connections that were in the way; unplug, clean, make sure they're a tight fit... then hopefully, u can run those trouble codes on that list i gave the other member... GL!
