tranny gauge temps???

[NC87GN]

Installed a B&M tranny gauge. Tranny is billet piece with a 9X11 convertor (true 3000) stall all from Bruce @ PTS. Also have a Maxicool tranny cooler, rated at 26000 for cooling efficiency. Running the cooler directly to the tranny bypassing the radiator. Also using some Dextron 5 with added slip additives. Question I have is what are some typical temps your seeing for those who run the temp gauges? I am seeing 120-130 highway temps and 135-140 city. Does this sound right? The gauge sender unit is tee'd off on the return line coming from the tranny cooler (basically measuring the fluid temps going to the tranny). Wondering if my sending unit is inaccurate?

Thanks

Trans Temps

Trans fluid manufactures generally say trans fluid should be 180 deg. I'd say your doing all right.

That is great!!!!

And very normal. Perfect I would say

That is great!!!!

And very normal. Perfect I would say. It will creep up under stall and city driving in summer but when locked will dive like a thermostat opening. Mike, That is awesome and yes correct. The whole time in testing it never got over 175 or so and we idle them after driving to get the hot pressures.
Again, awesome !!!!

How is it? You having fun driving it or what? Post back.

BTW..... WTF are anti slip additives. Man I dont know if I would do that.....

WTF are slip additives.. HEHEHE! Its probably just a selling gimmic. I picked 2 gallons up from the GM dealership down the road. Its called Dextron 5 which is a step up from the Dextron 3 that everyone uses.
Bruce, NICE CONVERTOR! I took the guy, who assmebled my tranny, for a drive today. Let him drive the car as I wanted him to make his own conclusion on the convertor. To make it short, you will be getting a phone call to build a convertor for his setup. He loves the spool-up of the 9X11. Difference is night and day from my POS stock convertor. Driveability is great around town. I am so happy I finally got the tranny right!

That is Great!!

It makes me smile to know you are ecstatic! That is great! Enjoy, Mike and if you need anything else do not hesitate to call or write. Super deal dude!!!

Wouldn't you normally want to measure the temp of the hot fluid coming OUT of the trans, rather than cooler fluid going INTO trans?

I'd think that fluid temp coming OUT would be a better, truer indication of what's going on inside trans.

after all, that's the normal setup with engine coolant.

Actually all these different temperatures all have a meaning. Monitoring the temp of the fluid going to the cooler is actually fluid leaving the converter. The converter, even when it's functioning properly, is the main source of heat energy in your fluid. If the converter is going away, you may see it here. The fluid leaving the cooler can give you an indication of your cooler's efficiency if compared to the inlet temp.

More importantly, this is the fluid that is entering the transmission's lubrication system; keeping the bearings, bushings & thrust washers happy. I monitor the fluid temperature of the oil in the pan. It's already been through the cooler and traversed the tranny lube circuit, picking up the heat of the transmission's bowels. It's also the temperature of the fluid being ingested back into the trans/converter too. That's what I'm most interested in.

Hey Greg-
That is what i am doing too. Sender in the pan. I run a N/L AC 9" 3500 stall convertor and a B&M 28000 cooler and temps i am seeing street VS racing are:
street cruising-125-150
racing on a 90 deg day-180 (180 in the water box), and 210 (210 after a run).
