Transmission rebuilt

I took my car to rebuild my transmission to transmission plus of Kissimmee , they estimate the work for $1250 including warranty labor and parts for 1 year, I decide to do it, I left my car . It took them 2weeks to kid it, I pay cash $1250 , I did not pay tax , because it was cash that's jesse the owner said, I went home, 2weeks latter I star having the same transmission problems, I took the car back. . And they told me ,they can do anything because they think is a electric problem. I lost $1250 . And my car is the same. Think twice before you take you car there.
