I have an 2002 grand caravan sport and I have a tranny leak but further back after it, it looks like a hose line. The fluid smells like antifreeze but not sure. Anyone knows if there a line connected

Sounds as if your heater core is leaking or you have a leak in the heater fluid hoses. need to check the hoses by the fire wall to see if you see any liquid staining. Also check the floor board inside to see if there is any moisture there. But for all accounts it sounds like a heater core or hose leaking problem.

Since the Caravan is front wheel drive, there would be no transmission lines running to the rear of the vehicle. This reduces the possibilities to either a fuel leak, or a brake line. If you smell the fluid you should be able to tell immediately if it were gasoline. This would be a dangerous thing. Fuel leaks must be isolated and repaired quickly to avoid risk of fire. If it were brake fluid, and the leak were stead, you should, if you inspect the brake master cylinder reservoir, a lower level of fluid than normal, possibly even a total loss of fluid in the rear chamber. If so, then the brake line to the rear has probably ruptured from age/corrosion. It must be repaired or replaced.

Does the radiator fluid look milky? If so, you may have a blown head gasket.

inspect your heater core

The horrible smell is antifreeze leaking from the heater core. This is the more serious of two leaks. You might be able to fix it with some stop leak. You can also tighten the power steering hoses.

It sounds like you have a couple of issues here, so lets start with the transmission one first. What it sounds like is that you have a busted hose, and the good news is that it is not expensive to repair. You will need to get under the vehicle and find the hose or hoses that are leaking and cut a piece of each hose off so that you can take it to the parts store and get the correct hose to replace it or them. I would recommend getting new hose clamps as well to re-attach the hoses. It also seems that you have some type of radiator leak if your vehicle is running hotter than usual. The leak could be a slow one and that could be the reason that it went un-noticed. The reason that the heater is not working even though the cars engine is hot is that the water that is used to cool the engine is scalding hot and that hot water flows through your heater core and that is how heat can be selected and blow hot air out of the vents. If there is not enough water, then there will not be any heat. This is some thing that you will also want to address immediately as if the engine runs hot due to a lack of water/antifreeze then you will run a high risk of damaging or blowing the motor and that would not be good. My advice is that you locate the cooling system leak and fix it ASAP to avoid some costly damage. A lot of cooling system leaks are, the water pump, radiator cap or bad hoses, so make sure that you check them thoroughly. I hope that you have found this information helpful as that is my goal.

This sounds like you may have a hole in your radiator. First pull your radiator cap off while the car is off look in there and see if there is any fluid in there. If not fill with antifreeze. Once you have done this wait a minute and see if it leaks out if so then there is a leak in the radiator. Next if this doesn't provide an answer look at your hoses you could have a leak in one of the hoses from the radiator to the engine.

The description you gave led to the water pump I guess. if its bad it will start leaking. Good luck

Radiators with plastic top and bottom tanks have a limited life and if they leak it is usually terminal and will probably need to be replaced. Any radiator shop can pressure test your system. Replacement is not a huge job but radiators have become relatively expensive.

check it out,sounds like a waterpump ,but it could be anything,you must be using 100% to withstand -30 celcius where are you alaska??
