SOS URGENT! Installed new transmission and slipping????

[Hunz]

So I just installed a remanufactured transmission from a place out of Texas. I got it all back in and drove it down the road and now its slipping on and off?!? What did I do wrong, does it have something to do with the torque converter?

Ck Fluid level or could be problem with their rebuilt transmission.

Are there any trouble codes coming up? Did you verify the fluid level, and if so how? I believe there is an important step in aligning the torque converter, did you do that?
