Yes you are right, never had a VB out. This is my first automatic all my other Mopars had 4 speeds. Anything special you have to do to drop the VB ?

Other than having lots of rags handy to wipe your arms off? Not really. Loosen and remove the two levers on top. Remove the three bolts at the front and rear of the VB and 4 around the accumulator (10 total). Lower the VB. Unless someone has removed it already, there'll be a large spring between the VB and accumulator piston.The trickiest thing is pulling it forward to free the park rod from the pawl at the rear of the trans and pushing it back in later. You might be able to just lower and rotate the VB out of the way while you remove the seal.

Being able to turn the driveline makes taking the park rod out a breeze.
Same putting it back in.
Once the VB is loose from the trans a light yank towards the front of the car and it should pop out.
The deal is, there is a stub on the end of the rod and it goes past the park lock and gets stuck until the park lever lines up with one of the cogs on a wheel.
This is looking at that assembly from the other side, so you can see what I mean.
The stub on the end of the park rod sticks through to this side, so to get it through there most of the time you have to turn the driveline back and forth a little to get that lock to line up with the cogs on that wheel.
