My uncle and I put in a new radiator the.other day, now I am having transmission issues could they be connected? My D light is blinking and tranny not shifting well. I'm about to check fluid in a minute.

Depends on what model year you have..
My TL-S for example does not have ATF Lines going into the radiator.. While I believe the 1999 model did have and I am not sure about 00-03 base models.

Its the 2003 TL. Automatic transmission

Only the 99 TL had the ATF warmer

Also I did check the fluid and it was WAY over full. I haven't added any fluid. I had a drain and fill done on tranny in september but I would think it would have shown signs of an issue way before now if they had put too much in it then. I read a little online and I seen some people say something about the tranny's temp gauge... I don't know a lot about cars but I assume I should learn cuz this car has given me nothing but problems. Lol

Start with draining the fluid....Obviously.

Pull all of it out. A little over 3 quarts should come out and then refill to the center of the line, make sure you drive the car a little before checking the fluid and it is on an even surface when checking the dip stick.

You should have a little fluid left over when done and dispose of extra fluid properly.

Yep. Whether it be this car or the next, its always good to know how to diagnose and/or fix your own problems. It'll save you thousands of dollars and countless hours of waiting on mechanics to figure things out for you.
