YACT: Automatic Transmission Cooler (Poll added)

But it could only reheat the fluid to engine coolant temp, which is proper operating temp for ATF

jc, listen to me very carefully, the torque converter is responsible for 85% of the heat generated in the average automatic transmission, the transmission fluid inside the torque converter and the rest of the tranny is above the correct operating temp (190F to 230F), this hot fluid is thus cooled by the in-tank radiator cooler, it is not a question of how cold the fluid in the lines are, it is a question of the B.T.U. cooling efficiency of said cooler(s).

I think it's funny that people are taking this discussion so personally.

See the reason I'm concerned about the fluid being too cold is because I live in Michigan, where in the winter the temperature gets below freezing about 4 or 5 months out of the year. The transmission cooler I have to install that my dad bought isn't a tiny little cooler... when I saw it I noticed it was quite a bit larger than the B&M I use in my old car. I called a parts store to try and figure out what's it's rating is, and I couldn't get a BTU rating or anything from them, but the box says it's good for mid to full size vehicles towing up to 2500 lbs. (it's a Hayden part #403 as seen in this pdf document on page 53)

I guess I'll install it like the instructions say to and if it has a problem warming up in the winter I'll just tell him to drive it like he stole it to get it warmed up

The correct solution to the temperature problem is to install a thermostat bypass, like Roger said.

OR MAYBE JUST DONT LISTEN TO ME?

If your so worried about it, get an elec. solenoid, to run the stock one, then when it gets hot goo dual. Or get a thermostat controlled cooler like I have for my engine oil.

Or get your shorts in a knot because nobody listens to you and everybody hates you. :roll:

I agree with Roger's statement on this matter. The only time I have ever run a aftermarket cooler before a stock cooler is when there wasn't a stock cooler available. I.E. Custom Street Rod or a older Manual to Auto conversion.
