1999 Mercedes C280 Tranny Issues Still! Have Fixed and Replaced Items 3 Times HELP!!!

[Icucme4]

I have a 1999 Mercedes C280
I purchased the car well traded not knowing much about it but it is and was a huge step up. Same day I got it the battery died I left lights on for a few, jumped it to get going again. A week later had transmission fault codes and tranny felt like it was slipping wouldn't drive after it got hot.....
I have since replaced the TCM, The Entire Valve Body, The Plug, - Each 3 Times and recently the wire harness from the tranny to the tcm.... I managed to get the car running anywhere from 3 days to 3-4 weeks longest this last time... But after an hour in traffic suddenly the tranny went again
I got codes
0753 - Shift Solonoid "A" Electrical
0758 - Shift Solonoid "B" Electrical
0763 - Shift Solonoid "C" Electrical
0745 - Torque Converter Clutch Circuit Electrical
0715 - Input/Turbine Speed Sensor "A" Electrical

I have replaced All common problems but when I replace TCM all is well and intermittently it goes out I can't tie it to anything specific most of the time I need to be driving for a while for it to happen. I strongly feel its electrical, A relay, bad ground.... I don't know how to test for this...... With that said I have an unrelated error code P0410 I believe it's for the secondary Air Pump... but whenever I fixed the transmission and this code would also intermittently pop up but easily clear out causing no issues.......
I need transmission Help I'm at a loss I never had fluid on the plug or in the TCM I don't know what's wrong please help!!!!!
I had the car at an independent shop at one time we thought we had it fixed this last time it lasted 2-3 weeks ran and drove like a dream and after a good hour and half of driving the transmission code P0700 popped up then the other codes came after I tried to clear them - What is causing the TCM to trip out????
