Tranny Temps With Stall Converter??
 

Im putting in my tranny temp gauge and a 3000 stall converter this weekend. So, since I don't know how hot my tranny is getting now, I won't know If its getting too hot after installing the converter. So what is the normal operating temp. stock and where should it be at with the stall. Also does anyone tow with a stall, just wondering how thats gonna go. It already has an stock external oil cooler on it, I'll probably put a bigger one one later also.

Thanks for any info

i can't really say what is normal or any before and after temps but on my truck with an external cooler and electric fans my tranny temps seldom get over 200deg's. i can hot lap it at the track and it takes quite a few runs before my temps get over 200deg's and when they do i take a short break and let it cool off.

towing can be hard with a converter. i figured out with my truck and my last truck that if the tranny is shifting up and down a lot just go ahead and put it into 3rd gear. it will stay locked up much more of the time and the temps will stay down.

my goal of keeing the temps under 200deg might be a bit extreme but i wouldn't let things get much over 200deg for very long.

I feel normal operating temp is between 160-180*. Anything after 200 is pushing it IMO. I would get the biggest/badest cooler you can get in there asap. Vince

Mine never have gotton over 175-180* and that was in 109* summer heat. Normal range is 150-160* even at the track. I have a big cooler and a 2800rpm stall.

2600rpm stall with a hugemongus tranny cooler. I see 160* tops. Sometimes it doesn't even see 100* like this morning when it was 35* outside.

My stock cooler with a 2600 stall saw tranny temps of 200* on a regular basis. No towing, no running at the track. Just daily driving.

I run a Trucool 40,000gvw cooler, its hard to see in the pics because the Radix heat exchanger is in front of it. It's almost the exact same size as the intercooler.

on the hwy, mine stay dead nuts on 140*.... when I beat on it and play a little they creep up to around 180*... never seen it over 190*, dont plan to LOL...

I don't race alot at the track, but I agree with all of this, especially the 3rd gear deal. If you do tow alot and have the ability to tune, I'd change your tow/haul settings to help you not shift up and down so much causing the unlocking/locking to happen too much.

I have a larger cooler, 2800stall and I drive back roads from/to home/work-so I have quiet a few stop and goes, converter locking and unlocking alot. About 45 minutes of never getting up to 60mph. By the end of that 45 minutes I am usually at 200*.

I have noticed, it takes a lot of highway driving to bring temps down to normal, normal being around 160+, once it makes it to 200*. If I drive in DC all day I will see 225* eventually.

I guess I need a bigger cooler... and I have a stock converter :(
these readings are off the stock gauge in the dash (denali cluster):
I've never gotten over 200*
it will easily get to 200* in the summer driving home in stop and go traffic
driving on the highway in cool weather will net ~185*
driving on the highway in summer will net 200*

I'm running a stock thermostat for the engine, which I think has a lot to do with it. My cooler lines go from the tranny to the radiator to a B&M stacked plate cooler behind the grille.

I don't tow alot but I do a fair amount in the summer, Flat bed with my T-Bucket on it to car shows, so not too much weight, or my small popup camper. I probably tow 10-15 times a year. Anyone using a cooler with the fan mounted to it? That seems to be the way to go.

Thanks for all you advise guys.

after seeing where my temps were I contacted a friend at a local Yamaha dealer, he grabbed me a radiator fan off of a totaled R6. after mounting that to my cooler I have seen no changes with or without it, however keep in mind that I'm reading off a stock cluster, which if it's like the engine temp. it's in no way accurate.
