Simple find and replace with AWK

I am trying to write a find and replace script with AWK and I can't seem to get it to work. I need it to find this exact string *P*: and replace the P with a T or just replcare the whole thing with *T*:.

this is what I have tried
Code:
awk 'BEGIN {gsub(/\*P*:/,"\*T*:"); print}' ${INFILE} > ${INFILE}.out

to replace exact string, you can try not using / /
Code:
awk '{gsub("*p*","")}1' file

Code:
awk '{gsub(/\*P\*:/,"\*T\*:"); print}' infile

Remove the BEGIN and escape the second * in the pattern and replacement too.

Does not work, just does nothing.

Get this message
awk: warning: escape sequence `\*' treated as plain `*'
and then is sits and does nothing.

Code:
l> awk '{gsub(/*P*:/,"*T*:"); print}' infile
lala *P*T*:lala

If you have nawk on your system try using that. Or try that one:
Code:
sed 's/\*P\*:/\*T\*:/g' infile
lala *T*:lala

If still nothing of this works on your box, post a snippet of your input.
