harsh downshift when slowing fast

[cknies-3802]

the aod in my car has a very rough down shift when coming to a fast stop. seems like the converter is not releasing,the converter is a fresh rebuild. i checked the tv adjustment , engine idle, etc. is it possible the vss sensor could be bad.i think the vss is supposed to tell the computer the car is slowing down.how do you check the vss sensor? any ideas? thank you

The only time I experienced hard downshift while slowing was when my TV cable was set too aggressively. It was like I was downshifting a manual trans each gear while coasting down. With an auto typically you can coast from full cruising speed and really not feel a downshift as you approach a stop. This was not the case. I have since backed off on the TV adjustment and it is much better. I have a stock AOD with only a Lentech valve body (stock converter).

Hope you sort it out.
