Read File_2 and store the values in a hash. You can then copy File_1 inserting the new lines as required. For example

#!/usr/bin/perl
use strict;
use warnings;
#use Data::Dumper; 

open FINAL1,'<','File_2.txt' 
     or die "Can not open Input File_2 : $!";
my %max_trans = ();
while (<FINAL1>){
  next unless /\S/; # skip blanks
  chomp;
  my ($pin,$value) = split ',',$_;
  $max_trans{$pin} = $value;
}
close FINAL1;
#print Dumper \%max_trans;

open OUTFILE,'>','File_3.txt' 
     or die "Can not open Output File_3 : $!";
open IFILE,'<','File_1.txt' 
     or die "Can not open Input File_1 : $!";
my $pin_name;
while ( my $line4 = <IFILE>){
  print OUTFILE $line4;
  
  if ($line4 =~ m/\s*pin\s*\(([^)]+)/g){
     $pin_name = $1;
     $pin_name =~ s/"//g;
     print "$pin_name\n";
  }

  if ( $line4 =~ m/^\s*direction\s*:\s*output/g){
    if (exists $max_trans{$pin_name}){
      print OUTFILE "      max_transition : $max_trans{$pin_name};\n";
    }
  }    
  
}   
close IFILE;
close OUTFILE;
