Need some possibles of what鈥檚 wrong. I just bought and installed the Z tazer. After install I of course took her for a short drive to try out the mods (feels beyond amazing btw definitely recommend).
I parked and popped the hood to make sure everything was good and boom. Red fluid on hose directly connected to radiator and also on the split from hose connected to coolant reservoir.
Prior to this I had taken her to 3 mechanics and asked them to check trans/fluid because of hesitation/airy feel during acceleration ESPECIALLY when in eco mode. Which was why I bought the Z to bypass eco mode since I manually couldn鈥檛. Only one said they THINK i might have a trans issue but they couldn鈥檛 be sure and to just bring it by if it got worse. Other 2 acted like I was crazy.
Anyways now I see this and it was just confirmation I was right. And would definitely appreciate any feedback on possible solutions.

If it's red fluid it could be the transmission cooling lines that are connected to the transmission cooler (located in the front of the radiator). The fluid could also be engine coolant (antifreeze). Used fluid can look red after exposure to air. If you need to add antifreeze, check the Owner Manual to see if your 2013 uses OAT (Organic Additive Technology) or HOAT (Hybrid Organic Additive Technology) antifreeze. Do not mix the two types of antifreeze.

ECO mode vs MDS. ECO mode is just a light on the instrument panel that indicates you're driving in a manner that is economical on gas. MDS is where the engine changes from 8-cyl mode to 4-cyl mode. ECO and MDS operate independently from each other. The ECO mode light can be On/Off in either 4-cyl or 8-cyl mode.
You can turn the ECO mode light Off (disable it) using the Uconnect menus. Use the "+ More" button to scroll to the Display settings. Within the Display settings is the Fuel Saver Display settings. Here you can select On or Off. Select Off and you will not see the ECO mode light again.

To disable MDS you will need an engine tuner (e.g. DiabloSport) to change the settings in the PCM (powertrain control module). The Z-Tazer does not change any of the parameters in the PCM.

a Diablo is next on the list for sure. And thank you so much for the info.
I made an appointment with the dealership on Monday for the emission recall that hasn鈥檛 been taken care of so I鈥檒l squeeze a diagnostic for the leak when I drop it off.

I am thinking more of a radiator leak than transmission. Did the coolant level drop in the reservoir tank? You could have something as simple as a bad thermostat. Is the car overheating?

I hate seeing folks getting ripped off at the dealership. But if you are comfortable with them doing the diagnostic and the high price, get it all knocked out with one visit.
