Transmission Fluid leak. How difficult is it to fix myself?

I just inherited my Mom's truck. A 2005 Tacoma. I recently took it to get an oil change and the mechanic took a picture of a leak. He explained that it is leaking transmission fluid.

I am pretty low on funds since I am disabled and am currently surviving on savings until my disability insurance goes through. I use the truck to go to my doctor's appointments which are an hour away and the next one is 3 weeks from now. I would like to fix this myself so that I don't have to spend the little money I have left on labor. I have a jackstand and some basic tools. Is this something I could tackle myself even though I am not that mechanically inclined or would this task be best left to a professional? I consider doing an oil change myself to be somewhat easy... just messy if not super careful. Might this be as easy as buying a new gasket? if so, will it be difficult to install a new one with just basic tools? Does the leak point to a bigger issue which I am not seeing? Any help will be appreciated, thank you.

 

That looks more like a rear main seal leak on the engine, very unlikely that the front transmission seal is leaking.

Doesn't look like it's leaking too bad yet.

Either way to fix it the transmission would have to come out.

 

Pop the little black plastic piece off and see how much oil comes out.
That will tell you how “bad” it is.

As Dm93 said, the Transmission has to come out.
So in terms of difficulty, I’d say it’s a 7 out of 10 if doing it in a garage with hand tools.
Maybe a bit more difficult if it’s a 4x4 and it is cold outside. Cold sucks. Transfer cases suck. Driveshafts suck.

 

If you have to ask…you’ll probably have to take it to a transmission shop

 

Doesn't look like trans fluid to me, looks like motor oil.

If you are capable of considering this repair to save $, you could change your own oil and save a bunch. Every time.

I say clean the area with degreaser, monitor the leak, and if your oil level on the dipstick doesn't move, don't fret over it.

 

motor oil is gold clear or black, slippery, and doesn’t clean.

Trans fluid is red, thin, and cleans

each smell different

that pic shows clear gold fluid

5ATs are known to leak from the rear not front.
