The 904 in my dart has been causing me much grief the past couple months.

I swapped converters last spring and it seemed fine at first but after about a 50 mile cruise it was obvious something wasnt right.

Eventually we pulled to stop sign near the house and it stalled. I was able nurse it home but it stalled in the driveway and at that point would not go forward any longer.

I pulled and rebuilt the transmission. The band lining was gone, dragging and the high gear clutches were totally vaporized but everything else looked good so I assumed that was the problem but once I put it back together it still dies in gear.

It has a manual valve body with all new clutches/steels set to spec.

It will move in reverse but still doesnt seem right at all.

I'm wondering if the transmission locking up may have ruined the new converter. I think the stator goes between the turbines so maybe it smoked the stator?

The converter did feel weird when going on - like it was super stiff to turn and usually they spin easily.

I'll be pulling the transmission again this weekend and curious if the gurus have any tips for anything I should check while its out again before reinstalling with another new converter?
