Pictures of the solenoid contacts:
BTW, the original solenoid on the transmission when I bought it was a 12 volt (the car should have been converted to 12 volt) RBM 1AR11-62 (completely out of order) and I replace it with a good used (according to the seller) 12 volt RBM AR10B62A.
As it seems that I need to purchase a new solenoid, I am thinking to buy one 1AR11-62.
Any difference between the 2 references above ?
