77 Auto Trans modulator install/removal

[MH77280Z]

Hi Guys,

I am speechless where the modulator is located in the 77 280z. Mine is automatic. What is the best way to get this thing out?

Also, seems like this is a threaded modulator but on the other end of the modulator there is no way to tighten it? its all around all over!!!

The modulator is located on the driver side, about 1/2 way along the transmissions length, down low, just above the pan.

It is threaded and just unscrews from the transmission case.

That part I know. How do u get it out? The exposed end is all round and there is no way any socket wrench will work. Also when u put a new one is it just hand tight?

Maybe a strap wrench?

Yeah let me find a smaller one tomorrow. Problem is it is right next to the exhaust pipe and there is hardly any room.

Also, I think it does explain possibly some smoke i sometimes see in the exhaust at starting. The vacuum hose at the manifold has transmission oil. So the modulator is definitely gone.

There was a plate holding the rubber tube to the modulator. Once I took that off there was a decent clearance if not ideal. Placed a new modulator and my trans fluid somehow was at L, topped it off as well with a qrz. So far it is behaving better now at low and high rpm range in terms of shifting now.
