Most common Sherman tank in Soviet use was M4A2 76mm. In fact it was looking like M4A4 for it had 'wet stowage' (that is common for late Shermans)
2015 of these were sent to Russians - out of 2915 manufactured. (my data are slightly different from what you can find on Wikipedia)
It had 2 diesel engines...
"The Soviet Union's nickname for the M4 medium tank was Emcha because the open-topped figure 4 resembled the Cyrillic letter che or cha (Ч). The (diesel engined M4A2) "emchas" used by the Red Army were considered to be much less prone to burn and explode than Russian tanks.
A total of 4,102 M4A2 medium tanks were sent to the U.S.S.R. under Lend-Lease. Of these 2,007 were equipped with the 75 mm gun, and 2,095 carried the 76 mm gun."
