Maybe, although I doubt they can get there.
Transnistria is a bit of a strange case. Stalin created an "Autonomous Soviet Socialist Republic" in western Ukraine.

Then he annexed the portion of the province of Moldavia between the Dniester (Nister) River and the Bug in the summer of 1940 when attention was focused on France. They created the Molavian Soviet Socialists Republic.
The Soviets exiled a large number of the Romanians living there, and brought in large numbers of ethnic

Which included some of the Moldavian Autonomous Soviet Socialist Republic, but not all. The pink region below when back to Ukraine.

This demonstrates that ethnicity and the desires of the local population mattered not at all to Stalin.
When the Soviet Union came apart, Russians, especially in the area on the other side of the Dniester/Nister River (Transnistria) seceded from Moldova. Then Moldova seceded from the USSR.
If Russia does not establish a ground link with Transnistria, the "republic" will be vulnerable to pressure from Ukraine. The Russians would like to establish a land bridge to Transnistria so they can move more troops into the region (Russia has around 1,400 "peacekeepers" in Transnistria), but I doubt they can get that far.
