I have a slight leak in the front end of my 2001 Ford Escape XLT 4x4 V6. It might be the front differential, I'm not sure. I'm not too familiar with transmissions. I slowly drips red fluid, which I'm assuming is ATF. Are there any products on the market that are safe to use and work well at stopping slight leaks like what I'm experiencing? If so, what do you suggest?
 
Start with a full flush of the ATF. Could simply be spent fluid not treating the seals with respect. A high-mileage ATF is an option.
 
I suggest finding the problem and replace the offending seal. From my experience, that has been the best way to go. It might take more time and cost more money, but it's the best long-term solution.

It depends on the reason for the leak.

If the ATF is old and dirty, you may have a very small particle of something between the seal and the shaft allowing a leak.

A run with Auto-Rx might save dropping the transmission and replacing the seal.

Also, draining and refilling with new ATF may do the job.

If the seal is sound but worn, some of the high-mileage ATFs contain additives that will "swell" the seal and buy you some additional miles. There are also additives that do the same thing.

Finally, if the seal is totally worn out, or torn, or damaged, you need to replace it. Nothing you can put in the ATF will fix a ruined seal.
