93 lesabre wont kick down
 

Hello I have a 93 buick lesabre 3800 starts and runs fine but it just seems like its guttless and wont Kick into passing gear you can downshift on the colum and its ok so i dont think its nothing to do with the trans.Ihave changed the control moduel and adjusted but still acts the same it seemed to help a little. Also Talked to the garage about the fuel filter and they say my car doent have one(seems a little strange to me) but I cant find it anywhere either.I thought it may be a sensor but Im getting on service eng soon light.any suggestions would be a big help.....
