I was planning on changing the trans fluid/filter in the interceptor tomorrow and had read previously somewhere you could detach the "in" line to the trans cooler, start the car, and cycle through the gears to pump the entire system dry of ATF - just shut the car off as soon as the flow lessens or it spits a bit.

Read a friends Hayne's manual and it just suggests dropping the pan, swapping the filter/gasket, and replacing the 4-5 qts you drained that way.

Seeing as there's 12 qts in there total I like my method a bit more - I'm not going to cause the trans any harm by draining it this way am I? Just want to make sure before I start...

Thanks
