i have this o6 ih ce300 with dt pre dpf with allison 1000/2000 series trans its leaking trans fluid out of the hole at the bottom of the i guess it would be bell housing or the adapter plate it came in few weeks ago it was down like 7 quarts so i ASSUMED it was the front pump seal it was dripping badly so pulled trans put new seal filled her up and took for a ride and still have a steady drip coming from the adapter hole could it be the front pump gasket? any ideas?

Here's the other thread on this. I'm the one that did this. However, from your description I don't think this is the same as yours.

29536478 Gasket
29540130 Gasket

These are the two numbers I have from 2016. You will also need some sealing washers and o rings when you put it back together.

Each bolt has a sealing washer. I'm not sure which o rings I replaced. Looking at the picture in my book, there a a couple of o rings on the front pump.

You probably should just call your Allison Dealer. The parts department should be able to help you.
