The engine / tranny pull has gone pretty well up until I got to these trans cooler lines on the passenger side of the Th350. How the heck am I supposed to get these bolts off? There’s no space to come in from any angles to screw out. What am I missing? I’m pretty close to just cutting these guys and buying new ones.
If your crossmember is a bolt in you can un bolt it and lower transmission enough to get a good angle on it , or remove trans mount temporarily to lower for access
Hmmmm. My TH400's lines are pretty easy to access and don't appear as buried as your 350. It appears the two lines have been crushed a bit on the bends already, so cutting them off and replacing anyway is probably advised. What is the pipe in the foreground right side of the pic - the exhaust? Perhaps once this is removed access will free up a little.
Eric P is right that if you remove the cross-member the trans will drop down nearly 5-6". You'll have to remove the cross-member when pulling the engine and trans, so it's all part of the process anyway.

I lowered my 78 350 to replace the transmission lines (as Eric describes) but do use flare nut wrenches...makes life easy.

Leave the lines connected at the tranny for now and disconnect the lines at the radiator. Pull the engine/tranny as an assembly, and the lines will come out with it.
When you do the re-install, attached the lines to the tranny once the tranny is mated to the engine and drop the whole thing in with the lines attached so you don't have to re-attach them once the tranny is in the chassis.

Crows foot flare nut of the right size will get that done. But I agree, new lines look to be needed at this point which will require the correct tool as well.
