KA24DE - idle problems

[ILuvJDM]

I replaced the radiator for my ka24de with a ka24e radiator which are the same except the transmission cooling line inlet and outlet on the rad (present on the ka24de not on the ka24e). My car is still (unfortunately) auto so I had to use a barb and connect the line because there was no inlet for it anymore. When I started the car to do the coolant flush I forgot to pug the maf in for the first run, car ran like shit and I plugged in the maf, fixed. Fast forward - the transmission line fell from the hanger, a hole was rubbed and I lost fluid and all grip from the clutch plates and had to fix the line and re-fil. Post transmission line hole the following is happening:

Car is idling LOW, like 500-600rpm and despite being totally stock is not keeping a steady idle.

Its auto and if i remove my foot from the brake it doesn't move

The clutch (I mean torque converter.. oops) is slipping in all gears but 3-4 and it sounds like I am driving stick for the first time. (tranny is blown i'm assuming but this could relate to the idle problem)

I've reset the ECU thinking the maf re-programmed itself when I left it unplugged and that had no help, fluid levels are good.
Help??
