No coolant is suppose to be in transmission. How it got there is easy, you radiator has transmission lines running through the bottom of it. Your radiator has an internal leak into those trans lines. You'll probably find oily substance in coolant also.

Have a 2004 jeep grand cherokee and when i push on the gas peddle it makes a knocking noise and the heater seems to have gone out at the same time

Heater 'gone out' = low coolant. Knocking noise = internal engine damage? Maybe low coolant = internal engine damage.

My Jeep grand Cherokee 2.7 2003 mixes oil with water in the reservoir.

engine oil brown, or ATF oil, pink/red/maroon?
did you look in the rad neck , and then drain out some (by any means)
rad coolant to a jar
let it settle and LOOK, see that oil pool up.
and say, (engine oil or ATF to self?)
first check transmission oil (at dip, or drain it)

if it has has any signs of milkshake color, (cream) BINGO.
the 14psi coolant is pushing in to the transmission too.

try to understand. this:
trans cooler in rad, bottom can be breached.
when you start and engine the trans pump pushes AFT to the rad.
then when engine gets hot, the 12-14psi RAD pressure reverses this flow , coolant to trans.
why not pressure test the trans cooler next, or first.

I have a 2004 Jeep cherokee. My engine light came on today after i got gas. also i had trouble pulling off. felt like the transmission

Stop by a local parts store like Autozone, Advance, etc.. and have them do a FREE OBII scan (fault scan) They'll pull up all the faults that computer has stored and will give you an idea as to what triggered "eng light". Could be as simple as a loose gas cap.

Yes, in back of your engine block, there two freeze plugs, these plugs hold water or coolant in the block, to replace these freeze plugs, transmission will have to be remove, if your going to get this done, I would also have the rear main seal replace at the same time, should not cost you much labor to do this, due to if it starts to leak oil from there in the future, transmission will have to come out again, this will save you money and time down the road, hope this was very helpful.

Is it really the engine which starts running, or is it the hydraulic cooling fan which makes a lot of noise due to the high coolant temperature? Since the temperature drops down rapidly when you start driving, the problem seems to be with a restricted airflow from the cooling fan. Was the radiator changed lately?
Take care in not overheating this engine, because the heads can warp (coolant leak) and/or it can start dropping a valve seat.
