tranny problems?

P0740 tcc circ mal
P0753 shift solenoid A circuit electrical
P0758 shift solenoid B circuit electrical
P0785 shift timing malfunction
P1860 manufacturer control transmission

All of these codes come on immediately after turning on key. I'm thinking I have a bad ground. This is my 70 with a LS swap almost done just working on the kinks... I don't think that all of this stuff is wrong with my trans.... Any help would be greatly appreciated!!
