Kia Optima 2001 6-cyliner Speed Sensor, Engine Light Problem
I have also a 2001 KIA OPTIMA with 6 CYLINDER ENGINE.
Same problem exist, it shoots into third gear while driving.
I find the most answers are in this problem is to replace BOTH, the INPUT SPEED SENSOR, AND ALSO THE OUTPUT SPEED SENSOR.
An easy way I usually find many parts for my KIA, is on Ebay auctions.
There is a lot of competition there, so you have a good chance to get a nice price, even if it has to be shipped from Korea. Most KIA dealers will charge more than what you would pay on Ebay. Also, the wait for the parts would be shorter if purchased thru Ebay than even from regular auto parts stores, that have branches thru USA and Canada. The little wait is worth saving the money, instead paying higher to a auto parts dealer.
