Re: TH400 Removal(I need some tips and tricks)

The easiest is a 36" extension, a wobble socket, and a 1/2" impact gun.

Otherwise a box end wrench, 1/8 turn at a time, from the top.

Is it leaking from the front seal ?

This is the way. These bolts are a pain! I also have found it somewhat helpful to lift the trans tail housing up or pull it down to give you a little more access as the motor pivots a little on the engine mounts. To avoid this hell I usually pull and install the engine and trans as one connected unit. Good luck!

It's leaking from multiple points.

A ratcheting swivel wrench is another approach .
Especially if your have the frontend off.
