Is it engine oil or transmission fluid. If engine oil I would say rear main seal and if its transmission fluid I would say the seal around the input shaft
It's engine oil. It's not coming from the black plug to access the converter bolts. Man I'm scared to death it the bed plate. It just had the truck studs done 2 weeks ago!!!
Sounds like time to pull the tranny and find the issue. Could always remove the plug use a mirror and light and see if you can spot the issue. Or just keep driving it'll eventually fix it's self :hehe:
Check cam and crank sensors. Also check the top side of the engine behind turbo. The oil will travel on these things and make you think it is a bed plate or rear main.
