Thread: tranny temp gauge

Tweet

i was thinking about a temp gauge in my C-6 tranny. ive got a 4000 coan stahl and drive it on the street. is this something i should worry about? and if so where are these typically installed at on the tranny? and finally what temperature is a safe range for a tranny to run?

IMO, 4000 stall is a little high for the street. My understanding is the higher the stall the more heat generated.

Some of our experts will know more though.

I like guages because they can show signs of failure long before its dangerous or costly most of the time.
Be nice to have one in the rear end of a performance ride.
Its like a airplane the more you can see thru guages ,the more you know about whats happening on the ride.

I'm running a circle track converter with a 2500-2700 rpm stall. TCI told me it has a bit tighter clearances than their less expensive street brands and will be more efficient on the street. My car should cruise at 70 mph at about 2700rpm.

I have a trans temp gage located on the output line to the cooler. Sump or return line temps are OK too but may not be as responsive as the output fluid temps. Is that important? Maybe, maybe not. On expensive turbo gen sets we monitor supply and return temps with alarms on both. Of course it ain't too difficult to relocate the sender either.

I'm running a 2400 rpm stall behind the 462" Buick in my 32 roadster.

It does ok, but on long grades and running under 55 mph it will generate excess heat because it hasn't fully locked up.

It flash stalls about 2800-2850 rpm or so.

Denny that makes sense to me. Of course these older cars ain't got huge dash boards for lotso gages either.

thanks for the insight everyone, i was fairly certain 4000 is a bit high for the street. that is what is concerning me on my tranny temperature. just never crossed my mind of where to put the sending unit or how high temps should run on it. i will for sure get one in there soon!

Geez, Denny. There were fewer gauges on the first Mercury capsule.

Just to add to the conversation, my trans supplier recommends trying to hold the pan temperature to around 150*. He does that because the temp in the converter runs higher - and you can't measure the temp there. The 150* pan temp makes sure the converter temp is safe. BTW, he only builds 700R4 and 2004R transmissions.

I put a SPDT switch on my dash, and use a single gauge to display both water temp and trans temp.

For what it's worth . . .

Lookin good Denny.

Shoot you got room for more! I like gages and switches (and wires too for now)
