Does your tranny have a jerk to it when you let off the throttle?

I looked at a 97 12 valve yesterday with a supposed HD transmission. But when you let off the throttle it has a slight jerk which the guy was saying since it's heavy duty, it's just the tranny "grabbing", he claims. Also he said it only has 20k miles on it but doesn't have any paperwork or service records, and doesn't even know who the tranny came from. He says the last guy put it in, and he works at a shop too. I'm not sure if he is blowing smoke up my or what...

mine has a slight clunk if i abruptly let off the pedal when locked in overdrive. i just had it rebuilt w transgo shift kit upgraded clutches and billet single TC. it did this before the rebuild also. i just use a lock up switch which makes it much smoother

mines the original trans from 96 and has had nothing but regular maintenance, no upgrades at all and it does it all the time.
