My new tranny is running too hot. Driving around town, the temp hangs right around 230*, but occassionally goes upward of 240*. The tranny is a Rossler T2 TH400. I have a B&M 24,000 GVW trans cooler on it. Apparently, thats not big enough. What cooler do you all recommend I use to bring the temp back down?

You could go to a bigger cooler 30000 gvw or even two but what stall are you running and is this temp just after a hard run or a stall up ? But those temp though a little high are not really that bad , Also where are you measuring at ?

I am running an ATI 8" 4000 stall converter. It goes up to 240 sitting in traffic, or moderately accellerating in traffic. I'm not sure where its measuring from.

Thats undestandable with a 4000 stall I would bet the temp is off the presure port or in the line feeding the cooler, I would not worry about it to much , CHECK OUR FAQ PAGE ABOUT TEMP ON OUR WEBSITE

if you're worried go with a tranny cooler with a fan... The b&m has a thermostat that initiates the fan at 170F so you have no worries... it's worth the money...

Can I buy just the fan and use it on the cooler that I have?

Several companies offer just the fan and that would drop you 10- 20 degrees on average from my experince

Do you sell a fan that would fit good on a 24000 cooler?

No unfortunatly we do not presently sell anything other that trans and converters but that will be changing soon

What rear end ratio are you running? I see that you are running an 8" converter. That converter is definitely creating a lot of heat. When you are driving around town what RPM are you driving at?

I've got 3.90's in the back. Around town, the rpm's are usually around 2000.

With and 8 inch 4000 stall and that gear you are going to generate alot of heat at lower speeds under stall. Remember energy is never lost only changed and the slipping of the stall at low speeds is actually turning the energy from the engine that is not being transfered to moving the car into heat. Sounds like you need a fan or additional cooler or both.

If you are driving around in 3rd try second and see if that helps with the trans temps. My concern is that your motor might run hotter using this method. You definitely need a big cooler with a fan and need to try to reduce the slippage in the converter. Vince

If you like visiting salvage yards :-), you might find a small fan off an import that will work nicely as a tranny cooler fan (~ $5). Also if I am not msitaken, some trucks had fans on their oil coolers that can fit your application. Then wire the thermostat to kick the fan on via a relay at a predefined temperature.

There is a reason most cars and trucks do not have trans temp gauges on the dash. The reason is because it will scare the crap out of you! It is not uncomon at all for the trans fluid to run 20 deg. hotter than the engine coolant. Your typical engine temp gauge goes to 260 deg., while your typical trans temp gauge goes to 300 deg.. I personally wouldn't bat an eye at 240 deg. trans temp.

While seeing *240 in traffic may not be of concern in traffic, that does not mean there should not be some way of increasing cooling capacity by utilization of a fan as an example...

The problem with high temps in suburban areas is we tend to forget how long that fluid has been in there and it becomes glazed in a short period of time. Which leads directly to premature failure of soft parts... seals, clutches, bands ... etc.........

Good Luck,

260* for engine temp seems high to me. I get worried if I see over 210*
The trans should really be kept cooler than 200* IMO. If mine gets over 165* I start paying close attention. Heat kills transmissions, period.
You may have to work harder with a 4000 stall to keep things cool, but it is worth it.
BTW, I run a 40K cooler.

when was the last time you changed your fluid? as the fluid breaks down over time it resists less and less heat

Its a brand new transmission with brand new fluid.
