This is what I get with Yace with a full set of tablebases:

1.Td1 Le6 2.Te1 Ld7 3.Tg1+ Kh6 4.Kg3 Kg7 5.Kf4+ Kf7 6.Te1 Kg6 7.Te3 Kf7 8.Kg3
Lc8 9.Kh4 Kg6
  ±  (1.28)   Tiefe: 31/50   01:15:18  1203546kN
1.Td1 Le6 2.Te1 Ld7 3.Tg1+ Kh6 4.Kg3 Kg7 5.Kf4+ Kf7 6.Ke4 Le6 7.Kd4
  ±  (1.29)   Tiefe: 32/51   01:39:17  1469856kN
1.Td1 Le6 2.Te1 Ld7 3.Tg1+ Kh6 4.Kg3 Kg7 5.Kf4+ Kf7 6.Ke4 Le6 7.Kd4
  ±  (1.29)   Tiefe: 32/51   01:48:42  1545246kN

So I don't think it has really found anything interesting.

I had a look at some somehow similar positions in Dwojetzki's endgame university
book, and I would be very surprised if your position were won.
