If you are only dropping the pan when you drain your A/T you are not doing it right. There are drain plugs on the torque converter and an access hole in the bottom of the bell housing portion to access them.

Drain the pan and also, turn the engine with a socket and ratchet at the harmonic balancer until one of the torque converter drain plugs is accessible through the bell housing access hole. Remove the drain plug and drain it as well.

By draining both the pan AND torque converter, you will drain 99% of the fluid from the entire a/t.

Carrameow,

I was not criticizing you or your method. I very much respect your thoroughness in car maintenance. I was only warning people that doing this to an a/t with burnt fluid may very well have some bad consequences.

You're doing your part to keep these great old machines on the road. Good job!

Have a great day,
