torque converter ATF

[asti84]

I just had my 84 300TD ATF changed. I gave my indy 7 quarts to replace the ATF. But his asst. gave me back three of the ATF bottles he did not use. It did not occur to me at that time but now I realized he may not have changed the ATF in the torque converter. Is this a correct assumption? I used to use up all 7 qts. every ATF change. Is there any harm if I change the ATF in the torque converter 30k from now (next ATF change) The car has orig tranny with 302k on it.

thanks a lot guys! nice change on the website. keep up the good work.
