It was classic case of "after the Lord Mayor's show" as the Daggers slipped to their seventh home league defeat of the season.
Hopes were high with Wayne Burnett's team going into the match iin good spirits after winning their previous two matches.
Another win here would have been a massive boost, with Tranmere down with the Daggers at the wrong end of the table.
Victory would have opened a nine point gap between the two and given the Daggers valuable breathing space. The setback means the pressure is still very much on.
The only consolation for the home side is the fact they were beaten by a wonder goal from Tranmere midfielder Max Power.
He lived up to his name in the 74th minute when he settled the issue with ferocious 25 yard shot after he took a crossfield pass with the Daggers stretched.
His finish had pace as well as power and gave Mark Cousins
It was one of very few worthwhile attempts in a sterile match the Daggers should have won on the balance of play.
They had more of the ball, but failed to make it count where it mattered most, in the opponent's area.
Despite dominating for good spells they never brought a save out of Tranmere keeper Fon Williams until the last minute when he went full length to hold a shot from Ayo Obileye.
Obileye also headed a good chance wide and Jamie Cureton
was just too high with a header. So anther game that should have been won was thrown away to the disappointment of the fans.
Dagenham & Redbridge:
Cousins, Batt, Obileye, Saah, Doe, Hemmings (Widdowson 61), Bingham, Labadie (Jakubiak 77), Chambers (Boucaud 61), Cureton, Agyemang.
O’Brien, Murphy, Porter, Yusuff.
