I've read other posts on how people have installed a temp gauge. I'm wondering which gives the most acurate reading, putting a T in the line coming out of the transmission, or removing the bolt just above the linkage on the drivers side and putting the sending unit there. I like the option of removing the bolt above the linkage, but read in a post that no oil will run out when removed. If no oil comes out of the hole, how will the sending unit work?

 

i put mine in the line coming out of the trans with a tee from harware store. the reason i put it there is this is the hottest the fluid in the trans could be.i also added a B&M aluminum pan that is finned and holds 3 xtra quarts of fluid. it takes a long time for the fluid too get warm now,with that xtra capacity means GOOD FOR TRANS ,IMO

 

I don't know exactly how tranny fluid flows in the transmission, but that bolt you're talking about removing is in the port that is used to check line pressure. I've got my electric tranny guage sensor mounted in there (threads in with no problem), and its temp readings were matched up exactly with the autotap temp readings when I scanned my tranny not long ago.

 

Thanks for the info guys. I really don't want to cut into the line unless I have to. I'll try removing the bolt and putting it there, autotap it and compare. If it's off I'll splice into the line.

 

you can use a tee fitting and some compression fittings from a hardware store. cut the line with a tubing cutter its no big deal really !

 

I agree, its not a big deal at all, I've used the compression fittings on other projects. You have to know me, I'm very **** about the way things look. I just thought it would look better in the side of the tranny.

 

T it into the line exiting the tranny. It is a lot more acurate and responds quicker to temperature changes.

I used to have my gauge hooked up through the hole in the side of the tranny just because it was easier to install. I always knew that it showed a temperature that was pretty accurate for trips and stuff, but after a run at the track it took a while for the gauge to rise.

When I got my new tranny put in, Dave at Rock-On T'ed the sending unit into the exit line off the tranny and it seems to be a lot more accurate. Shows about the same temps on the highway and stuff, but responds a lot quicker to temp changes. The time that I see this the most is when you brake stall the car. You can brake stall it and the gauge will actually start moving. So, you can get much quicker response than that. And I think that is important while racing at the track.
