I've got my trans temp sender in the port right above the shift linkage. I think this is where lots of people put them to avoid drilling the pan. Is anybody getting accurate temp readings with the sender in this location? Obviously it's not as good as in the pan, but is it good enough? I drove the car for the first time today since putting the gauge in and although it was barely above freezing outside, the trans temp barely went above 100*F. Sound right for stock converter?

 

yes, thats about right. I installed the sensor in the service port and notice it barley gets to 120 when its 20* out(i got an extra large trans cooler too). I installed min late summer and temps were around 165* and checked it with auto tap and it was the same temp.

 

Little off topic, biut what the the auto meter part number for the trans temp sending unit?

 

I have mine in the pressure test port and it reads almost the exact temp as datamaster reports.

Sending unit would depend on gauge. For a short sweep electric gauge most of the time the correct sender is part # 2258.

FWIW, I've got my sender in the service port, and I'm running a "Dope" style cooler setup, and I have to beat on the car hard as **** during the winter to get the temps above 100*.

I'm talking back-to-back-to-back WOT runs to make it even *think* about rising.

 

i have my sender inline with the exit port of the trans that goes to the radiator, in a t style fitting trans is alot hotter than 100 though you should think about putting it there, that is where the hottest reading will come, right after it exits the converter.

Which line exits the tranny and which one goes back in? I know one of the lines goes to the top just behind the radiator cap and the other goes to the bottom.

 

The line with the hose and spring clamp flows toward the trans.

 

if you are under the car the line that is towards the driverside near the trans. after the lines come down from the trans ans flattenout and follow the floor it is the driverside line. that is where i put my t block with sender

 

WOT isnt goin to cause more heat than stop and go traffic.

 

here is the best i can do, the gauges are bright but look just amazing, hope this helps

 

Which line is the output line as you look at the fittings on the side of the trans, the top or bottom fitting? My car is a conversion and I am not sure if I routed my lines the same way as GM did.

 

where did you find T? lowes, home depot maybe?

 

I think i got the t from menards, they didn't have 2 3/8's or 5/16's holes(i can't remember what the size of the lines are??) and a 1/4in for the sender. So i had to get a 1/4 all the way around T then get to conveters from 1/4 to 5/16or3/8(cannot remember again). The sender went in the 1/4 inside and the top of the t was for the trans line

 

i dont have a jack here at school but i am sure someone can use my directions and help you out by jacking up their car and finding out or you, maybe i can squize under there and see... if noone can findout for you

I bought my T at Ace Hardware, but anyone who has brass fittings should have one. I have a 1/8" NPT sender and in order to keep it from blocking the flow I bought a 1/4" T and a reducing bushing to go to 1/8". I am going to use 1/4" to 5/16" compression fittings to connect it to the lines, but I think that f-bodies use 3/8" line instead of 5/16" I will post pics when I assemble it.

Don`t worry about trying to squeeze under the car, I`m not in a rush, everythings stock so I don`t think I have to worry about overheating the trans..............at least until summer comes and I start hot lapping it at the dragstrip

 

Heres a couple pics of what I put together.
