4R70W Shift Solonoid Underpowered- Causes?
12 May 2024, 08:00
Hey yall. I'm troubleshooting my US Shift Quick 4 that controls my 4R70W as it is saying that my shift solonoid A (SSA) is underpowered. The manual said that it could possibly be because the circuit is open. Any thoughts on how to fix this? I believe the open solonoid is also the problem behind the mysterious parasitic draw on my battery. Also, would anyone know why my EPC is powered? Below are some pictures of Solonoid current and resistance readings. Any tips or advice is appreciated...
