I did replace the front and rear seal and trans pan gasket. and my 4r70w is leaking again I think the leak is coming from above the pan, maybe
the top of the trans? Its hard to tell. do you guys have any ideas?
check where the tranny dipstick line connects. It should be put in with a new o-ring, but mine ended up leaking anyway since i couldn't force it in enough with the bracket bolted to the upper bellhousing. I ended up using high temp RTV
