In the picture of the old Chrysler the top is off his power steering filter canister! He had it and the trans flushed and refilled Both with auto trans fluid at a trans shop!
I had to drain them and refill them plus the convertor LOL with 10 wt. non detergent oil the shop he took it to didn't know that! they also put in a new 8 volt battery and ran ground to the negative terminal when he tried to start it it would turn over backwards! It was taking him forever to start it till the engine went bang reversed rotation and ran!!! LOL Customers LOL
