Climbing on TECKY2 approximately 4;000 feet given climb unrestricted clearance to FL190 expedite through 7;000 feet. Aircraft given full power to approximately 3;500 feet VSI climb rate. Passing through 4;800 feet clearance cancelled to maintain 5;000 feet. Response to ATC was 'leveling 5;300 feet returning to 5;000 feet.' Our return to 5;000 feet was a bit slow and ATC prompted to return to 5;000 feet quickly.TCAS traffic was visible on and to west at 6;000 feet; but no TA or RA.  I don't recall exactly due to heavy radio traffic and MCP adjustments; but our course may have been approximately .5 miles west as magenta line randomly shifted during our turn on procedure possibly causing NorCal to cancel climb; but we were not notified of that.  NorCal then reissued the exact same clearance passing abeam traffic at 6;000 feet. Flight continued uneventfully.
On the TECKY2 Departure from SJC; I initiated a 30 degree right hand turn from MLPTS; but noticed I was tracking inside of the magenta line; so rolled out to approximately a 15 degree banked turn to match the magenta line and the white one minute airplane track line (as well as the flight director in LNAV). ATC issued a climb and requested we expedite through 7;000 feet. The Pilot Monitoring deleted the reduced climb thrust and we began to expedite the climb. About half-way through the turn the screen refreshed and the magenta line all of a sudden was well inside the turn. I returned to 30 degrees of bank. At approximately the same time ATC told us to level at 5;000 feet. When I looked at the altimeter we were passing 5;000 feet; so I initiated an immediate level-off; reaching approximately 5;400 feet. I then initiated a slow descent to 5;000 feet. After approximately a minute; we were once again given the climb with a request to expedite through 7;000 feet. We continued the SID and climbed normally.
While departing SJC on the TECKY2 Departure; the crew received an expedite climb clearance which was shortly followed by an immediate level-off clearance. There was TCAS traffic in the vicinity; but no TA was received.
