How do the transmission lines come apart at the radiator

Is it the power steering hose or a transmission line.Honda does not usually attach power steering lines to the radiator, but the transmission cooler lines are attached to the bottom of the radiator. If it is the transmission cooler line leaking, simply replace the line from the radiator to the transmission with 1/2 inch transmission line and some new clamps.May want to do both lines while you are making the repair.

Tranny cooler lines usually are about 1/2" outside diameter steel or reinforced rubber going to a separate chamber in radiator side or bottom. Always one in and one line out separated by about 10 inches apart. You can follow those lines back to the tranny.

they both should be different sizes to keep from this mix up

What type of engine is in this car. i can tell you this, the radiator removal on this car is not an easy one, let me see if engine size makes a difference.okay here we go,remove the negative cable from the jumper terminal or battery.
1) drain cooling system.
2) remove radiator upper cross member.
3) remove the upper and lower radiator hoses
4) remove the transmission hoses from cooler
5) remove oil lines from cooler if it has them,
6) remove connector from cooling fans and then remove fans.
7) remove the a/c condenser bolts located on the front of radiator.
8) remove fastener holding bracket for transmission cooler lines to left side of radiator. left side is driver side.all views are done from inside car.
9) lift a/c condenser upward to disconnect from radiator and then set back down on lower cross member. no need to open or discharge a/c system,
10) lift radiator up and out , careful not to damage lines or condenser.
I will enclose a few pictures to help you locate a few parts to remove.

Your trans cooler is located inside one of the radiator tanks and would be expensive to replace.
You can either replace the radiator with new or used or cut the lines and install an external cooler as is used for towing. If the cooler in the radiator is leaking, you need to flush the system to remove as much oil as possible or it will cause hoses to soften and fail. Also wise to change trans fluid as well.
Always use double clamps when running rubber lines for cooler so they don't slide apart under pressure.

Unfortunately you may not like the answer. The manuals cal for you to take the entire front end apart, including the bumper. I'll tell you, you will have to take the front end almost apart. Start by removing the battery, negative post first as this is necessary to the airbag sensors. Remove the battery and the tray. Next remove the electrical power distribution box and lay it aside. mark and remove the hood latch so you can line it back up on the install. Now there are several bolts to remove across the radiator shroud brace remove them and note the different lenghts so you can return them on re-installation. drain the radiator and remove the hoses top right and bottom left. If you have an automatic transmission you will need a special tool to remove the lines (found at your local parts stores). On the bottom of the vehicle you will need to have removed the protection shroud. once you have the lines and hoses disconnected you will need to remove the headlight assemblies by the bolts and not the adjustment rods. there you will find behind them a plug disconnect for your airbag sensors on the right and the left as well as two bolts on each side remaining in the shroud. remove the shroud by pulling up and to one side or the other while pulling out on the bumper at the top. after this there will be two brackets at the bottom to remove the radiator. The radiator will come out through the bottom of the car. To continue with removing the a/c radiator (condenser coil), using the same style tool for removing the transmission lines, disconnect the lines and remove it as well. Remember though to have the freon properly drained if the system is still charged as the intense pressure can cause injury when taking the lines apart. Installation is the reverse of the dis-assembly.

Remove the pressure cap. Place it aside for the new radiator.

Drain the coolant into a drain pan. The drain valve is located at the bottom of the radiator. Twist it counterclockwise until the fluid starts to drain. Close the valve when the coolant stops draining.

Locate the transmission lines at the bottom of the radiator. Ensure you mark both of the lines so you will know which one goes where. Unscrew these with a line wrench. Plug the line with a towel to prevent the transmission fluid from leaking out.

Unscrew the radiator hoses at the top and bottom of the radiator. The hoses are held on by hose clamps that can be loosened with a flat head screwdriver. Slide the hoses off the radiator with your fingers after the hose clamp is loosened.

Pry the overflow hose off with your fingers. The hose slides over a tube at the neck of the radiator.

Unscrew the mounting bolts at the base of the radiator. There will be one bolt on each side which can be unbolted with a socket wrench.

Unsnap any sensors connected to the radiator. They will have quick connect fittings that can be undone by separating the tabs and pulling apart.

Unscrew the fan shroud with a socket wrench. The fan shroud will slide off the top of the radiator. You can also remove the cooling fan as it is held onto the fan clutch by four small bolts. You will need a socket wrench to remove.

Lift the radiator out from the hood. You may need assistance as the radiator can be heavy and awkward to lift.

Removal

1. Drain engine cooling system as described. Disconnect upper radiator hose (8260) and lower radiator hose (8286) and radiator overflow hose (8075) from the radiator (8005). Disconnect the transmission oil cooler inlet and outlet lines from the radiator.
   

1. Remove cooling fan motor,fan blade (8600) and fan shroud (8146) assembly as described.
   

1. Remove radiator upper bracket retaining bolts and remove bracket. Lift radiator from vehicle.
   

Installation

1. Position the radiator into the vehicle. Install upper brackets and tighten bolts securely.
   

1. Connect the transmission oil cooler lines to the transmission oil cooler fittings.
   

1. Install cooling fan motor, fan blade and fan shroud assembly as described.
   

Engine Cooling Fan Motor, Fan Blade and Fan Shroud Assembly, Electrical Removal

1. Disconnect (pull apart) the male-female cooling fan motor wiring connector at the side of the fan shroud (8146). Remove the male terminal connector retaining clip from the fan shroud mounting tab.
   

1. Remove two fan shroud upper retaining bolts at the radiator tanks.
   

1. Lift cooling fan motor/fan blade (8600)/fan shroud assembly past radiator (8005), disengaging fan shroud from two lower retaining clips.
   

Installation

1. Follow removal procedure in reverse order.
   

1. Tighten fan shroud retaining bolts to 5.2-7.2 Nm (46-63 lb-in).
   
   

HOPE THIS HELPS.

It's likely rusted out transmission cooler lines. Only way to tell is to take a look under it. Might be able to see some of the line by opening the hood.
