I will be installing my deep tranny pan, cooler and temp gauge soon. Where do you think I should put the sender? Weld in the pan, or tee off the cooler lines? It seems guys have different opinions about this. Some say put it on the out port while others put it in the pan.

w/ a deep pan you don't want to put it there it provides some cooling so you will get a low reading. you want to put it inline on the outbound line from your transmission as close as possible to the trasmission so you get the highest reading (closer to what is inthe tranny)

I thought about that but istn't that really the temp from the torque converter and much higher than the actual tranny temp? (assuming a wheeling situation when the torque converter is not locked up)

IMO it's all kinda relative. I installed two temp gauges and two senders. One sender after the trans, one after the radiator trans cooler. What I learned, is, what situtations causes trans temps to climb, and the stock cooler doesn't do very much, and the trans becomes a big heat sink. Once it gets hot the stock cooler takes forever to cool the trans. I installed a remote, fan powered cooler. When I see the temp at a certain point, I hit the switch. In less than 5 minutes the return fluid is 40* cooler. It still takes a while befor the "out" temp starts to drop.

For what it's worth

What kind of are you running this set up on? (pull rig or trail)

What kind of temps are you running?

If this is a newer GM auto, there is a plug on the driver's side, hidden behind the linkage. AutoMeter sender screws right in, and it works well enough for factory development gurus.:D

Agreed. Although my experience is Dodge/Chrysler.

There are 3 factory test ports on the passenger side of my 48RE (04 Ram CTD) and my 44RE (98 Durango)...

I'm using the rearmost port. There's a write up and pics in the "Trailer and Tow Rigs" forum. Temps have been verified accurate with infared heat gun.

Mines a DD, but I do a LOT of trails near Death Valley. Will probably never tow anything heavy. I wanted to know what situtations would cause trans temps to climb, and be able to do something about it when it did. Some situtations surprised me. Once trans GETS hot, it tends to STAY hot. Having the gauge shows when it starts to rise, having the remote, electric fan cooler lets me keep temp in the acceptable range. I rarely let temp exceed 200*

Does anyone know if there's already a spot to add the censor on a C-6? I've head the guage for a little while and haven't gotten around to installing it yet. I'd like to see about getting that in there but wasn't sure if I'd have to braze it in the pan or of there was somewhere else to install it.
