This evening, I replaced the trans filter with an OE filter, cleaned the magnets and put a bead of RTV silicone around the pan and refilled using KIA SPIII.
After replacing the fluid and buttoning everything together, I started the car and put my foot on the brake and shifted through the gears. Reverse seemed to shift abruptly and sort of banged into gear. Drive seems to be refusing to engage first gear (even if I select "L", but maybe engaging a higher gear (perhaps third gear). It was immediately obvious that there was a problem because the car wouldn't creep forward when releasing the brake. Starting off from a stop feel as if the parking brake is on, but the car rolls freely in neuitral, so I know the problem is within the trans. Also, I noticed a Check Engine Light which upon scanning, revealed a "P0755 Shift Solenoid B Malfunction" error code. I cleared the code to see if it would return. The code never returned, but the problem persists. I checked fluid level again and it seemed to be overfull (now that the tranny was warm), so I drained about a quart which seemed to put me at the low mark of the dipstick (still within acce[ptable range). The only thing I can think of that I did wrong is not waiting for the silicone to dry before adding fluid. I feel like it's unlikely that the silicone contaminated the fluid, but I suppose it's possible. Any ideas? I'm super sad. Just bought this car and love it to death. Now I feel like I broke it by trying to refresh fluids. The Internet seems to have a few causes for p0755 code, for example, bad solder joints on a ribbon cable inside the trans, but I feel like it would be unlikely that such a problem would be kicked off by changing fluid and filter.

I've only owned the car a few days.
Car was running perfectly prior to this problem.
Although the previous owner wasn't diligent about maintenance, the car seemed to run fine.
Thanks for any help.
