The same old question here, the transmission in my 2002 tl is not shifting from 1st to 2nd, but when I enge in the tronic shifting, it works fine! I noticed a hard shift between the 2nd and 3rd gear but i can go on shifting smoothly till the fifth. I checked the fluid and it was fine. The TCS light and engine light are now on. I was washing my car today and when i finished and started running the car i had this problem right away. Could it be an electrical problem because of some water getting under the hood and the transmission is still fine?

I just wanna calrify that I meant sequential shifting when I said "tronic"

you ckd the fluid at 15 minutes freeway drive warm? between the dots?
color and smell was good- red fluid- no burnt sugar smell? reallllly???? hmmmm

have you done any fluid change to see what the drain plug looks like?
its magnetic for a reason

SS/tronic mode uses a higher `line pressure`- it will force a weak shift to happen and
keep you going for a while longer

What codes are you getting- parts stores will scan for free (except Ca.)
those will help us

It is possible for a selenoid wiring to get wet or have bad connection somewhere
Have you ckd the battery cables? any crud at terminal end = crud inside cable causes all sorts of problems
Recent ziner reports of how cable looked good on the end- or a litle crud on end,,then cut open the cable to find is was eaten away inside!!

Negative/Ground cables are really important too
bad signal from any sensor due to voltage issues can trigger false codes and bad running

do you get any slipping at shifts? -rpm goes up but gear wont engage until you lift off the gas?
thats a real problem

Problem just started after washing the car? Always go to last work performed. Gotta be careful about getting water in the engine bay. Ask me how I know.

hey guys, thanks a lot for your replies and special thanks to 01tl4tl.

So, here is what I did. I restarted the computer by taking off the battery cables and taking off the navi and clock fuses. surprisingly , the transimssion worked fine after that. It was my mistake not to check the engine light codes before doing that. Anyway, the transmission fluid was contamindated, although I drove 10k since I changed it, I ended up changing it. There was also corrosion in the positive battery end, i took care of that as well. The transmission shifts super fine and better than before. I drove about 80 miles mostly on highways since I created this thread. I did 100 mph and it was rocking. I cannot feel anything wrong with the transmission. I am lost here S:
