Transmission temps while towing

What do you think is the threshold for the transmission/torque converter temps before you stop and let it cool down? I personally don't like my TC to go above 210 and the transmission over 200. But I have never towed and just got a new TT

 

On level highway mine stays around 192. On hills it may hit 200. Steep hills kicking down to 3rd gear it momentarily climbs to 210. Never saw it higher then 215. But that was for just a second. I’m totally stock, I tow a light camper but get wind drag bad. I use ultra gauge

 

That's the transmission temps right? Not torque converter

 

Yes

 

I can watch pan temp and torque converter temps on my ultra gauge

 

I can too. When I towed my TT home Saturday, my temps didn't get above 175, but it was cool and on flat land without anything in it but a30lb propane tank and 15 gallons of water

 

Outside temps do have an impact on tranny temps. I was towing upper 80’s low 90 air temps

 

What truck and TT do you have? I have 2015 OR and jayco 195rb

 

Dry weight is 1948. It’s a intech flyer explore. Camper/toy hauler. 18 TRD sport

 

Here's mine

 

I love your trailer!

 

Thanks. It’s extremely versatile.

 

Very cool

 

I've got this printed out and stuck in the glovebox;
Watch both temps with a scanguage while towing, have had it up to 218 climbing passes.

 

Keeping transmission temps cool will greatly increase the life of your transmission !!!

I know this isn't applicable to a Toyota transmission but a competition built transmission like a TH350 that's in my Camaro .This Transmission has a transbrake and 4500 stall converter . Just engaging the transbrake for 10 seconds can see temps increase as much as 20° per second

 

Also monitoring Converter "out" temps can show an issue/ problem faster than pan temps . With converter temps you could see a temp spike of 20° after a hard pull with pan temps that trmp increase is much less noticeable

 

I did a heavy haul cross country and also did a long hill climb. Highest temp was 187F

 

Shoot, I have hit 195 (pan) on the beach in deep sand if I don't air down. I'm always watching trans temp. I know how important it is for the longevity of it

 

You might want to checkout pml covers for a deeper pan. I was fortunate enough to get one of their prototypes for half price as long as I gave them my feedback. I gained about 2.5 qrts of fluid.

Haven’t done any towing with it or hauled heavy loads. I saw about a ten degree drop in fluid temps in the pan. I still have the factory cooler.
