trans temp gauge sender / tranny line ques

[no1kicker]

I have a VDO 300 deg trans temp gauge that I'm going to install. I need a sender to hook up to where the tranny lines meet the cooler. Do any of these look good?

well depends on what tread/provision the manafold block you get has. I would get the 1/8. I also have a electric trans temp meter (Autometer), but no sender. I was going to getto fab a copper lined watter temp meter to work but too bulky.

Thanks for the input. I was going to try to get a 3 way adapter and put it between the tranny line and cooler. You wouldn't happen to know the thread size on the lines? :?
