Do transmission solenoids stop working at same time?

Question

My solenoid A,B,C, and D all have the same electrical problem issue. The transmission worked fine up to the point where I changed out the battery and alternator. After I changed out the alternator, I start getting codes about the solenoids. I don't really know much about transmissions so if anyone can help me out, would be great.

Answer 1

Was the alternator charging to much before you changed it? its possible to high voltage may have cause the issue. If the transmission is not shifting hard, and if you drain the transmission fluid there are no metal shavings inside you can just replace the valve body.

Its also possible its a wiring issue or bad ground. I would use a different OBD-II reader since I dont see p0753 in the service manual
