Good idea?...
As i am in a quandry now that i am havin a hard time finding the fittings that connect the trans lines into the radiator ,a thought occured to me and i am not sure if its good or not. Would there be a bad consequence if i simply elimated the trans fluid from circulating through the radiator?If i bypassed running trans fluid through the radiator would that affect anything such as computer ,engine functions, gauge temp,or engine temp?.the only negative i would think is that i would lose fluid capacity.I wonder if i could rectify that with a bigger trans cooler.I am not an expert, just a guy with a thought. please let me know your ideas Thanks

I have read in a few different articles that one of the reasons the builders pass the automatic trans fluid thru the radiator is that the transmission fluid works better when it is above 160. Running it thru the radiator makes sure the fluid doesn't get too cool......
*BUT*
..on the flip side, I know our resident retired transmission engineer disagrees with that theory.

running through the radiator is to cool the fluid, not heat it. that is why it is called a trans cooler.
if you want to eliminate the radiator cooler, you will need to install an aftermarket cooler in front of the radiator. otherwise you will cook your trans within 20 miles or so.

Correct me if I am wrong but I thought trans fluid temp should be 160 f and dosent the radiator run at 190-210 f ?2 there already is a trans cooler (stock of course).i understand it's a bit small but I'm sure I can purchase and retrofit a bigger one if necessary .

if you run 280 degree trans fluid through 190 degree engine coolant, it will still cool the trans.
that small unit under the radiator is the power steering cooler.
and on some vehicles, there is also a oil cooler.

Always keep the trans lines going through the bottom of the rad.

Why can't there be one single fluid used for everything? Just one single fluid change every couple months. Sounds so nice!

I'm not so sure about that. Although it would be more convenient, if a hose ruptures, you'd lose everything. Kinda like the serpentine belt. It snaps, no AC, alternator, power steering, no nothing.
