After working on it for the past week. I replaced the rear seal and oil pan gasket and oil pump. I went ahead and ordered some tracer dye. I think me overfilling it my not have been the problem. I’m starting to think it’s the front input shaft seal on the transmission. I know for certain now that nothing above the oil pan is leaking. I went ahead and checked the level of automatic transmission fluid and it is dry that’s with the motor running. If it is the fluid is super dirty. But.. I have a knock that sounds like a rod knock at the rear of the motor when idling I’m gonna pull the oil pan off and check the rear connecting rod bearings but might be a dumb question could a torque converter failure cause a knock. I’ll know more when I get the dye. There is oil pressure for certain not sure how much because it has a dummy guage on it. But I went ahead and replaced the oil pump but it was doing it before hand. I did check the the clearance between the rod cap and the journals of the crank with a feeler guage while the pan was off and they where still within spec.
Well this dang transmission leak is really pissing me off. I put a new seal in it. Pulled the pan cleaned it put everything back together and still leaking.. Gonna have to pull it again. I guess I’m gonna replace the pump and torque converter next. It’s not as bad as it was. When I pulled it the bell housing was all busted up. That’s another thing I replaced. After running it awhile with new fluid it’s back to being dark brown metallic color. The transmission shifted fine I never had problems with it before.
