The torque converter takes place of the clutch in an auto setup. But inside the trans there are bands and clutches, both. Bands are adjustable and if im not mistaken affect shift points and firmness. clutches inside the trans (most cases) are not adjustable and wear out thru time and hard use. Ford autos, AOD,AODE,C4 and even C6’s commonly fall out of adjustment. The trans will shift funny or not at all. I went thru this when i had a stock c4 behind my small block. Not that you were totally wrong, but i just wanted to clarify a little better.
