Where should it be for the best reading. Side the the tranny in one of the ports or should it be in the pan?

 

It really doesn't matter IMO, just so long as it is not on the return line from the cooler (false reading). Now if you were installing a pressure gauge, then I would definately place it on the capped port on the driver's side of the trans.

 

Since the pressure tap is already there, use it. Putting it in the pan requires drilling a hole and then sealing off the fitting so it doesn't drip.

 

Well it is a th350 and the pan had a drain plug so i could get a adapter to make it work.

 

I'm in the process of installing a mechanical trans temp gauge, It looks like the pressure port on the side is to small for the bung that is included. Do I have to drill the pan or get an adaptor to put it in the side?

 

Well if it is a auto meter gauge and sending unit, The little skinny one will thread right in th eport on the drivers side in the middle on thw 4l60e
