Had some issues with my transmission. Would flash O/D light and Check Transmission lights when driving on the freeway. When cold, it would shift right. Once warm, the shift would delay between 3 and 4, and delay and then shift hard into reverse. OD worked properly. Diagnosed it and replaced the solonoid module and put clean fluid back in to the proper level.

Now, the trans shifts smooth and no delay for 3 and 4 or hard shifting into reverse. BUT, it still gives the check transmission light and flashed the OD light when driving on the freeway. I drive up a hill to work and it through the OD light once, but 99% of the time it only comes on when driving on the freeway. OD works. Tried pulling the codes but it was clean.

Anyone has any ideas as to why it still throwing this light at me? Trans seems to be shifting smoothly and properly.
