i have the B&M Supercooler Type #70264 19,000 GVW 11 x 7.5 x 0.75" $40...i don't know if that one really is recommendable...both Matt93GXE and i have/had this one and we both agreed that this one brings the tranny fluid temp below operating temp...as soon as the weather hits about 40 ish, the tranny began performing terribly...Matt can elaborate a little bit more since he began to have minor problems IIRC...i am swapping mine out this summer for a different one...

 

they are that cheap! wow, I am going to get one.

Guys, what is the best one?

 

I agree with that contention......the sticky is more of an FYI than anything else.....I'm trying to avoid the this-is-what-you-have-to-do-tone.....

I may put a small disclaimer in there for people who actually experience the winter season.

From what I've read, the 16,000GVW one should be fine for all except TX, FL, and CA people....

 

I understand the intentions and reasoning...I think the small disclaimer could suffice especially for those who experience cold weather...thanks..

 

I am a New England Maxima owner, and am about to install a tranny cooler for the upcoming summer. I was wondering if even having one on my car in the winter will cause the transmission to be really sluggish. I was planning on buying the 19k GVW one, but have seen the advice and will downgrade to the 16k one. Is this the best option? Thanx.

 

yes...get the 16k one....it will cool the fluid plenty enough for you...

 

Im getting a tranny cooler is the 16,000GVW not recommended for people in FL b/c it's to small im in Miami...please help
Thanks,
Larry

 

the 16,000 will still be more than enough for our cars no matter whether you live in Alaska or the Sahara..
They're rated at 16,000lb because they're designed to cool the fluid enough for a 16,000lb vehicle. NOT a Maxima with a 4500lb absolute max capacity.. (3200lb car + 1300 people & luggage)

IMO, anything over 12,000 is overkill, especially in places where it drops below 40 for any point int he winter. my car got steadily more and more sluggish in the winter and only began shifting correctly when the temp got back above 60. It wasn't my driving that caused my tranny to be about 2 weeks from failure, it was the damn oversized tranny cooler.


for those that add ANY tranny cooler, I highly recommend covering at least half of it with plastic or cardboard during the winter (you see it done on trucks and busses and stuff like that for the exact same reason)..

 

It's really important to switch over to synthetic ATF if you use a trans cooler in cold climates. It won't get as thick as conventional ATF, so the transmission will work properly even with cold fluid. It still won't shift into OD until the fluid temp reaches 122F. Another reasonable thing to do is put the cooler in the feed line from the transmission to the radiator, instead of the return line. This allows the heat exchanger in the radiator to warm up the fluid. You could even swap the lines at the transmission in spring and fall if you want.
I would not use synthetic ATF that is marked for "racing". Its viscosity is a little higher, and will only increase cold weather problems. With the 70255 cooler and Mobil 1 ATF, my transmission acted fine into the 30's.
