200 4R getting too hot

I just got done reading this older post on the same thing

2004r's running hot ????

I have the level 3 BTO trans. I am having the same problem with it running way too hot. It takes it a good 10-15 minutes with the engine on(doesnt matter if I am idling or driving) for it to even warm up. But as soon as it starts getting warm, the temp climbs and does not come back down. In fear of messing something up, I have not tried to push it to see how hot it will get. I want to bite it in the butt before it gets to that point.

-BTO L3 200-4r
-5/16 steel braided cooling lines, brand new, no blockage.
-10x10x1 permacool oil cooler with 9" fan built in
-TV cable and all pressures have been measured and with in normal operating ranges.


The trans cooling lines do not go through the radiator. Should I have them routed through the radiator along with the cooler??

Does the more heavy duty trans normally run hotter?

Is the only way to solve this by putting in a deeper trans pan??

Ill take any and all input at this point...thanks

Yes, they should go through the Radiator to help warm the fluid to operating temp + water is 50 to 100 times more efficient at cooling than air.
A Heavy-Duty trans does not run hotter. A trans with a higher than stock stall converter will run hotter, the higher the stall/slip the more heat it generates.
A deep pan does increase fluid capacity and help cooling.
I've read several threads about cooling problems with BTO's trans, although I don't think BTO was the problem.
Found these a few days ago, good deal. >> http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWAX%3AIT
I also suggest you run a TH700R4 bottom feed filter with the 200R4 deep pan, Info here about 3/4 way down page. >> http://www.drwtransmission.com/thm_200-4r.htm
More Info about the filter stands that need to be milled/ground down to use the 700R4 filter. >> http://www.turbobuick.com/forums/tra...-deep-pan.html

Thanks for the info!!! and the links!!

I need to call them and ask what I can and can not do it because of the warranty.

Seriously considering the deep pan because my problem mimics the other post and that was the only thing that worked.

First I will reroute the coolant through my Rad asap because it wont hurt anything to do that.

I will post back once I have rerouted and tested.
