Best Way To Cool Down Tranny?

[jro909]

i tow rarely but when i do its quite a bit, what is the best method of cooling down the tranny? i know leaving it idle is better then letting it cool down while off, i mean do you guys use park or nuetral?

[Nytemare]

Park and neutral is basically the same position. Park has a detente to stop the trans from rotating. But it is for all intensive purposes..."neutral". As long as the pump is running the fluid circulates and cools. It would be better to go for a leisurely drive though to get airflow over the trans cooler... that would be the quickest way.

i read on here to use neutral with the parking break lol? i normally just let it idle in park a minute or two before shutdown

[Nytemare]

As long as the fluid is cycling and not stagnant it will cool much faster.

 

Neutral, park, driving...you'll get arguments for all of them...as long as you let it cool somehow, that's the main thing here.

 

If your really having a heat problem...invest in a fined aluminum pan (higher capacity than stock if possible), and a larger trans cooler.

Best way to cool it down is to never let it get too hot. Do you have an auxiliary trans cooler of sufficient size?

[jro909]

i have the stock z85 tranny cooler

Install a larger aftermarket stacked plate cooler, if you're towing much

I agree... A cooler running trannie is a HAPPY one.... Get her to hot and she will die (their is only one way to bake transmission fluid and after you have done it. ITS TO LATE)... If your towing much get a bigger cooler and install it..... you will be MILES ahead.

 

I am quite the jerk about leaks (I HATE leaks). So I would metal pipe it and rubber hose isolated it at the trannie or bust.... But Rubber hose will not leak if it is the correct type Weather Head makes a multipurpose hose that works good for this H10106(3/8 replace the 6 with a 5 for 5/16) and Gates makes transmission hose also. You need a hose that can handle HEAT, pressure, and tranmission fluild. If their is already a rubber hose cut the crimp shell off the hose but DO not cut the pipe. This will leave you with a place to clamp the hose down with out the chance of the pressure pushing the hose and clamp off. Under the crimp shell their is one hose barb rib. Make sure you place the clamp on the metal pipe before the rib.

does anyone know if my 2006 1500 sierra comes with transmission cooler? or is it an option? and were can i find it?

[jrod332]

it would be in front of your radiator.

On top of an auxiliary cooler, Full synthetic fluid would also keep the tranny temps down in the first place. Both will keep your operating temps down.

If your going to look at another pan look at this pan from Derale. It holds more fluid and WILL drop your fluid temps. No maybe it will. The links are below. A stacked plate cooler will help also. The cooler your transmission the happier it will be and your wallet won't hurt as often. I have a 4l80E so my pan is a lil differnt but that pan and cooler combo is currently in my truck. I haul appox. 15K practically 4 days a week and sometimes more and my tranny doesn't get warmer then 180. Keep in mind that is in the middle of summer. Mostly 150-165 any other time. Just my opinion.

i just installed that B&M tranny cooler yesterday on my truck and it is a very nice cooler, i dont tow anything, but in the city it would regularly get to 160-180 and with bigger tires i figured it would be nice to have, i didnt have a factory cooler so basically the radiator was also heating up the fluid and not doing much to cool it down

[stlavsa]

Its def important to keep your tranny cool, but its also just as important to address why its overheating in the first place.

 

Tranny cooler is good, but how about getting a tune? servos? gears? things to let the tranny work less. The tranny is slipping and shifting frequently, which is why the heat is building up. Cooler can help get rid of the heat, which will keep some of the wear down, and definately help, BUT it seems to me that its still going to be slipping and shifting alot, and still wear prematurely.

tonight i was driving around as usual it was 22 degrees outside and i would normally see around 140-160 and it didnt even get over 100 so it is a big improvement
