Q: Automatic transmission

Hi! Im dealing with this some time now, so first of when i do kick down it goes to 5,5 or 6 rpm and boom check engine light is on and car stops changing gears and shakes, if i switch it off its fine again but engine light stays on for about a day or if i pull out all ecu wires then it does the same thing. If im now kick downing but pushing it hard it goes to 5 rpm and only sometimes switches to next gear if i take of leg from gas for a sec and push it again it goes into next gear and it works fine. mm about year ago w/s stopped working it switches on display but does not switch the automatic transmission anymore and when im driving about 60 km it does 1.3-1.5 rpm and it eats fuel... may be you could suggest anything.

Thank you in advance.
