Freeze plugs between engine and transmission

[Natethegreat202]

Hey guys, currently doing an overhaul and dealing with lovely PO neglect. (98 TJ sport 4.0 ax15 98k miles) I’m getting ready to change freeze/expansion plugs, gonna do cooper so they don’t rust. I have my tranny pulled and out of the way. My question is how do I get to the plugs between the engine and transmission? It’s my understanding there is a freeze plug or two down there we can’t see. I have access to the ones on the side of the block and was gonna loosen the motor mounts and tilt the engine down to get to the one on the head. Do I have to remove the flywheel an all that To get to them? I’m assuming it’s necessary to replace them along with the others? Haven’t found a single write up or video about the freeze plugs that are hidden out of sight. My plug on the head started leaking so that’s why I’m doing them. Thanks y’all!!

1 freeze plug and 1 cam plug (lower right) between the motor and trans plus the 1 freeze plug on the head are on the back.

Thanks JKP! Awesome picture too I appreciate that. Do you happen to know if the cam plug is necessary to replace? Looks like I’ll have to remove my flywheel after all and I will probably just change both unless someone chimes in with some solid information saying otherwise.

The cam plug has oil on the other side, so unless it's rusted on the outside, it should be fine.

Awesome that’s what I figured. Thank you so much!
