Coolant leaked into tranny

[DFully]

I ordered a radiator for my 06 4.6L but immediately after I installed it a small leak started to happen. I have a warranty on the radiator so I took it out and put the old one that had a crack in the top but i fixed that temporarily with epoxy but after I installed the old one I drove it a couple blocks when I started heading back, the tranny was whining pretty bad. I’m guessing the tranny cooler lines got loosened during the ordeal and coolant was able to make its way into the tranny. I only drove about 400 yards but on a slight up hill, so my question is do you think it’ll be alright if I drain the fluid and change it along with a filter it should be okay? Or has the damage already been done? I parked it and am waiting for the new radiator before I try to do anything with it. I was just hoping to get an idea of what i should expect when i do start. Thanks for taking the time to read and any advice would be appreciated..

Coolant contamination is a death sentence for automatic transmission. You can try a fluid and filter and it might help 50/50 chance but the unit will prematurely fail at sometime without warning. Good luck.

First try to flush it with trans flushing machihe.
Of coarse oil filter should be replaced for sure

It is hard to believe for 400 yards to destroy your transmission.but anyways you need to flush all the contamination out and refill with fresh ford transmission liquid

In a FordTechMakuloco video he mentions that flushing the 6R60/6R80 transmissions need to be done with the transmission at operating temperature. This is due to them having a valve that will not allow fluid to be sent to the cooler until operating temperature is reached. Flushing when the temperature is lower just recirculates new fluid back out without it ever going inside the transmission. In your case you don't want to warm up the transmission and cause further damage. A pan drop at most will get a 60% fluid change which isn't good either. You might want to consider towing it to a transmission shop and have them get the contaminated fluid out. Or at least call one to see if they can flush out all the contaminated fluid.

With a mity-vac tool, take a sample of the trans fluid from the fill port. Coolant contamination should be obvious.

Sorry I’ve been busy but I just got my new radiator and am about to install it but I’m not too familiar with a mity-vac tool? What is that and where would i be likely to find one? I really don’t want to take any chances and i figure it’d be smart to check before I hook up the tranny lines to the oil cooler so I don’t contaminate it with any coolant tainted tranny oil if that is the case. Fingers crossed it’s not, but luck hasn’t been something that I’ve been too familiar with lately. Thanks for taking the time to hear me out and any advice is appreciated
