Regarding
Code:
ssh $trg grep  "'warning'  \$(ls /app/logs/*\$(date '+%Y').TFC-log|sort -r)"

You do not want to substitute any $-expression on the remote site by the calling site.
Then it is easier to use protective 'ticks' for the local site, so the remote side gets its contents unchanged. And have \' or " inside it that becomes ' or " on the remote side.
Code:
ssh $trg 'grep  "warning" $(ls /app/logs/*$(date "+%Y").TFC-log|sort -r)'

Or, assuming that ls -r does the same as sort -r,
Code:
ssh $trg 'grep  "warning" $(ls -r /app/logs/*$(date "+%Y").TFC-log)'

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
