how to reduce trans temps

[01maroonz71]

i know i know, 38's with 3.73's doesnt help anything, but my mileage on the interstate....but how can i reduce the temps in my tranny, they're hitting 250 after driving for about 30minutes or so. i installed the sending unit in the pressure port, which i hear is a bit higher, but i want it to be under 200 for sure, so i don't cook the fluid. when i checked the leve, it was ok, but a weird thing is that when i replaced the radiator about 2 months ago, when i unhooked the trans lines, no fluid came out at all....is that normal????


thanks guyS!!!!

good info and chart here. http://www.tciauto.com/Products/Cooling/

these work good also for plumbing the cooler in colder climates for faster warm up of the oil. http://store.summitracing.com/egnsearch.asp?N=700+4294924500+115+4294843279

thanks for the leak sweetk30

Make sure your converter is locking up. If it doesn't, that will cause excessive heat.

I have two sending units on my tranny temp guage. One in the return line from the 28K B&M stack plate cooler, and one in the pressure port.

The unit in the return line will read under 100 degrees , while the unit in the pressure port will read 250+ on trips of 20-30 minutes at interstate speeds.

simple... ditch the radiator aspect of the system, just run it thru the biggest stacked plate you can find... garauntee it'll drop temps big time...

but you need the fluid to warm up to a certin temp or it will cause damage over time. as taking it out of the loop might solve the problem short term.

hmmm...interesting....maybe i just need to move the sending unit to the pan, that way im positive what the temp is. DPI, do you have two gauges??? do you know what your actual temp is????


and also...how can i make sure my converter is locking up???? is there any way for sure?

get into OD and lightly press the brakes. if your rpms go up, its working.

just enough to activate the brake switch. so your lights come on.

yeah but he lives in fl, warm up shouldent be a big deal.

where do you have the cooler routed? befor the rad or after?

 

[01maroonz71]

i don't have OD, just a th400... the cooler is after the rad. i bought the truck like that, but have no problem doing it a better way if there is one.

Look where he lives... Florida? I'd never consider running it thru the rad... It'd be stupid...

And I run that way in Jersey... Awesome temps in the summer, 180, and it does get to a 150ish temp in the winter, just takes awhile.. It's a chance I'll take for the cleaner install and low summer temps...

Btw, You should know I've certainly been involved in many of these discussions and know the "boiling off condensation" theory..
