I all I own a 1998 Police Crown Vic. I got it from the police department I volunteer with. I have a leak in the transmission line where I replaced the line with high pressure hose. I believe the township had already done that once. Well, I did not do a good job and need advice.

I have new transmission fluid, a bottle of lucas, and a new filter and Gasket but before I can do that I need to figure out what to do. Any suggestions would be very appreciated.

First of all, replace those clamps with true worm-screw clamps, which is what you usually get at a auto supplier. They take up more slack than the press-on. Replace the hose, clean the tube, and use 2 screw clamps per side, off-setting the screw heads by 180 degrees. In other words, put the clamps opposite of each other. This has stopped every leak I've run across. And don't tighten them to the point you cut hose. You can CRUSH THE TUBING.

Also, be sure you use enough hose to cover the tubing about 1 to 1 1/2 inches on each side.

You can see where the old hose sat looks like the hose needs to be about 3 inches longer. The other poster suggesting 2 clamps is sound advice, also make sure to clean the lines well. Rust and contaminants can prevent a proper seal.
Would suggest fixing the leaks then change the filter, Make sure to clean old gasket off well and use RTV sealant or equal to help seal the pan.

I bought a drain plug, and installed it near the middle of the trans. oil pan after removing the pan, etc. Now, when I go to replace the filter, I simply open the drain cock and drain out approx. 4 1/2 qts of fluid. Then, I can remove the pan easily, and without getting drenched with fluid. Of course, you won't be replacing ALL the fluid, but you don't really need to. It is just easy to do it this way, and it is all that is really necessary.

Also, when replacing the filter, it (the filter) comes with a rubber o-ring...usually red in color. So, when you remove the old filter, many times the o-ring does not come out. It is easy to miss the fact that there is an o-ring up in the opening. So, you either must remove it from the opening, or remove the new o-ring from the new filter. otherwise, you will be forcing a second o-ring up in the hole..not good!

when removing the pan, take note of the torq registered on a tork wrench. I just did mine the other day, and I saw that the torq, as I was removing the pan, was approx. 20-25 ft-lbs. and so, when I reinstalled the pan, I made the torq the same on each bolt.

also, if you have a neoprene (or something similar) gasget, you can reuse for years. The autoparts people give you a new gasket, but I doubt you will get one made out of neoprene. I have never used these. my cr. vic is a '98, and I have replaced the filter and 4 1/2 qts of fluid about four times since I bought it (@69,000 miles...it now has 163,000 miles)
