There are two "areas" to be worked on: anatomic functionality (1) and
psycholinguistic processing (2).
(1) Stick your tongue out and try to vocalize as high as you do with your
tongue in your mouth ( assuming that's where you keep it when you
vocalize ). Can you go as far up? If you can't, try to practice with it out
until you're able to do it. That helps disengage the tongue-related muscles
from ALL and any vocal production you make. With it so relaxed, it's easier
for its tip to move independently from its back.
(2) Concerning that "r", it's basically American voiced /t/ as in atom, when
it's similar to the /d/ as in Adam. It may be easier for your nervous system
to "accept" keeping on "atttttttttttttttttttttttttom" rather than
"carrrrrrrrrrrrrrrrrrrrrrrrro amigo mio", as it already "knows" your /t/.
Best wishes,
Caio
