I think I know the answer but I just thought I'd double check. When installing the temp sender, it need to go in the line that comes OUT of the transmission, right? So it get's the hotest reading? I assumed this was right cause I don't think knowing the temp of the fluid going back into the trans. would be as important.

 

yes, the "out" line, if you want to measure how hot your tranny is.

 

Actually I would like to have 2 gauges so you can check how effective the cooler is, otherwise you have no idea.

 

It would be best to tap it into your tranny temp - so you will be monitoring the fluid inside the tranny and plus you dont need to ground the sender if you tap it into the pan.

however, to avoid extra work, I tapped it into the exit line.

 

or you can just have one gauge and connect two senders thru a switch so you can obtain both readings by using the switch. save a space for another gauge.

 

Thanks everyone.

According to the FSM, operating temps should be between 122-176 degrees. I'm curious to see just how much the tranny temp fluctuates the causes for the chamges. So as long as it's in that range I won't worry about 2 gauges. Although, I do have 2 more spots to fill in my DIN panel. Then I could put a oil temp in the last one and it'd be full. Decisions, decisions.

 

my area is 92F today and my tranny temp is 180 something on freeway and near 200F in local. If it is 60F outside, my tranny temp on freeway will be around 120 - 130F. outside temp affects your tranny temp a lot. btw, I have a re-cal'ed vb and tranny cooler.

 

Looks like I'll be tapping the pan. I don't know what I was thinking, but the sender is a little different than what I pictured in my head. It makes sense now that I see it, though.
