One way of tacking this task. First find the line number of the match on "Transaction ID" then pass through the original file looking for the lines before, equal, and after the the match.

Code:
mylogfilename="/path/mybiglogfilename"

TAB="`echo \0011`"      # Tab character
mytransaction_id="000000000000000"
cat -n "${mylogfilename}" | grep "${mytransaction_id}" | awk '{print $1,$2}'| while read mylineno mydata
do
      mylineno_before=`expr ${mylineno} - 1`
      mylineno_after=`expr ${mylineno} + 1`
      sed -n "${mylineno_before},${mylineno_after} p" ${mylogfilename}
done

uulog

uulog(1)						      General Commands Manual							  uulog(1)

NAME

       uulog - Displays UUCP log files

SYNOPSIS

       /usr/lib/uucp/uulog -f system [-number]

       uulog

       uulog systems [-number]

       uulog -s system [-number]

       uulog -x  [systems]

       The uulog command displays the contents of a log file of uucico or uuxqt activities.

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       uulog:  XCU5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

OPTIONS

       [Tru64  UNIX]  Performs a tail -f on the file transfer log for the specified system, displaying the end of the log file.  Use the Interrupt
       key sequence to leave the file and return to the prompt.  Prints information about copy requests involving the specific system.	If no sys-
       tem is specified, information is displayed for all systems.

	      Note:  System  name  can contain only ASCII characters.  [Tru64 UNIX]  Displays the uuxqt log file for the specified systems.  If no
	      systems are specified, information is displayed for all systems.	[Tru64 UNIX]  Displays the last lines of the log file.	The number
	      of  lines  is determined by the number argument.	(To display the lines, the uulog command issues a tail for the specified number of
	      lines.)

DESCRIPTION

       Individual log files are created for each remote system with which the local system communicates using the uucp, uusend, uuto, or uux  com-
       mands.

       Use  the  uulog	command to display a summary of uucp, uusend, uuto, and uux command requests by a system or systems. All of these transac-
       tions are logged in files under the /usr/spool/uucp/.Log/ directory.  The files are named daemon_name/system, where the daemon_name  direc-
       tory is named for the daemon involved and the system file is named for the remote system the daemon is contacting.

       The  uucp and uuto commands call the uucico daemon.  The uucico activities are logged in the system file in the /usr/spool/uucp/.Log/uucico
       directory.

       The uux and uusend commands call the uuxqt daemon.  The uuxqt activities are logged in the /usr/spool/uucp/.Log/uuxqt/system file.

       You can examine these individual log files by issuing the uulog command directly.  However, you can also have  these  temporary	log  files
       appended  to  a	primary  log  file that you can then examine.  This is called compacting the log files and is handled by uudemon.cleanu, a
       shell script in /usr/lib/uucp.

NOTES

       The uulog utility is marked LEGACY in XCU Issue 5.

EXAMPLES

       To display the uucico log file for system hera, enter: uulog -s hera [Tru64 UNIX]  To display the uuxqt log file, enter:  uulog	-x  [Tru64
       UNIX]  To  display  the	last forty lines of the file transfer log for system zeus, enter: uulog -f zeus -40 To display the uucico log file
       for systems pluto and venus, enter: uulog pluto venus [Tru64 UNIX]  To display the uuxqt log file for systems pluto and venus, enter: uulog
       -x pluto venus

FILES

       Contains log files.  Public directory.
