Since the search feature isn't working I was wondering if anyone could recommend a tranny cooler to use. I am looking at the B&M 19,000lbs, but was wondering if anyone had any experience with it or others. I believe I have seen in the past people mentioning that they have used the Hayden coolers. Any advantages of one over the other? Thanks...

 

Im not understanding why everyone is buying a tranny cooler? Is it really nessesary for normal driving? Is a tranny cooler an attachment to the radiator for more cooling or is it something else? hmmm

 

I dont have a tranny cooler but i have done some reseach (when the search function worked ). The Hayden 404 tranny cooler is the biggest Hayden cooler you can fit.

Because whaen you are running some serious ponnies the auto tranny needs help colling off so that you don't blow it up.

Hayden 404 is what I am running with around 300 ponies and it does the job.

 

Thanks for your input everyone. I think some people used the B&M or Permacool coolers, but not sure.

 

So if i have a stock engine i don't need one right?

 

Not needed but always good. The Maxima's down fall is the tranny (auto) and the front brakes.
and for the money it is worth it.

 

So i'm i have a weak tranny in my max, hmm, learning stuff everyday about this car. how long should i expect it to last?

 

no telling. There have been some people with little mods that it has died by 20k and others that have SC plus NOS and no problems. I think it depends on your driving habits and hmmmmmmm........LUCK.

 

Get the 130-70264 B&M Tranny cooler from Jegs. It is better than the Hayden 404 for one reason, it does not have an OPEN FIN design. Look at the Hayden cooler, it is basically a pipe with fins attached to it, yea it works, but design flaw in my opinion. B&M is closed, better cooling and less chance of breakage and leaking.

$50 from Jegs.com

boosting rocks my tranny temp to 200F from 2nd - 3rd - 4th @ 10psi....but tranny cooler cools it down to 180 right after that. recommanded operating temp is 80 - 170 F.

 

Its also better because it has a built in bypass for when the fluid is cold, it can detect the viscosity of the fluid so its much better for cold climates.

 

I use a B&M Cooler (70266* SuperCooler 28,000 GVW 11"x8"x1-1/2") (Probably is overkill, but i am kind of a Tim Allen type Arugh-Huh-huh-HUH) which is the biggest cooler they make... It fits perfectly if you mount it vertically infront. I would HIGHLY suggest you get the installation kit as well, as you will find the special straight-through style zipties very helpful for mounting the cooler to the Radiator. The stacked type coolers seem to be much more efficient compared to the same sized "pipe and Fin" type.
I autox with this car and I have defiantly felt a significant improvement to the amount of tranny slippage as the car gets hotter.

If you want any more info just email me.

 

This is what I've got. It's a great cooler - no matter what I do to the engine, I won't need to upgrade to a bigger size. And a great deal for $49 (plus shipping). I got mine from Jegs as well.

 

If you intend on leaving the car stock. Is the built-in tranny cooler enough?

 

I guess if you are in a part of the country with mild summers and you'll never be racing it. It's just an added prevention to extend the life of your tranny then. I'm hard on my car and I take it to the track sometimes. Cheap mod and can't hurt. Be sure to add extra ATF though to accomodate the extra capacity of the cooler if you get one.

 

it really depends on your driving habit.....you can still break your tranny if you torque brake and launch at every stop light.

for normal driving and stock car, the radiator will be enough.

 

Which installation kit did you use, if any? The only one I see is the Perma-Cool Maxi-Cool Transmission Installation Kit, will this kit work with the B&M?

 

Yes I used the PERMA-COOL installation kit, unfortunatly the only things that i used out of the kit were the Straight zipties and the mounting foam, as the fittings did not fit. I still would recommend getting it as you will be very hard pressed to figure out any other way to mount it cleanly to the AC condenser (the AC "radiator" if that gives you a better visual) and just pick up the fittings from a hardware store...I think i paid like 5 bucks for all the fittings needed. Get the 90 degree elbow fittings, as that will make your hose routing much cleaner as well.

 

Any writeups for this mod? I'd like to see how hard it is to install before I spring for this. Thanks in advance

 

it's in the 5th gen How-to stickie thread.

 

where did you put the cooler (fluid flow wise)? between the tranny and radiator OR between radiator and tranny ??

 

Mine is between the Radiator and tranny. I believe every install that I have seen has it mounted like that.

 

wouldn't it be better to lose heat before going into the radiator, thus also, keeping the water temp from rising? which in turn cools the whole engine.

 

Forget about the water temp the tranny cooler in the rad is a very small portion of the overall rad cooling effect.

We want to cool the transmission fluid. In the stock configuration it is warmed up in the radiator in cooler weather because the radiator is hotter than the trans fluid. When the trans fluid gets hotter it is then cooled in the radiator because the trans fluid is hotter than the coolant.

What I do is bypass the radiator cooler in the summer (just use the B&M) and connect it back in for the winter. (Cuz its cold here) The last thing I want to do in the summer is add heat to my trans fluid.

 

It's recommemnded to mount the aftermarket cooler in front of the engine radiator. As far as routing the tranny lines: Tranny out -> stock tranny cooler -> aftermarket cooler -> Tranny In.

The reason to put the cooler after the built-in tranny radiator is because the engine radiator itself will partially heat the fluid back up (When the engine itself is hot - the radiator is very hot. Stock tranny cooler is part of that radiator). There's a number of racing sites that say this.

Hope this helps.

 

When you mounted the cooler you said that you mounted it vertically. Is that so the hot fluid would go into the top fitting and the cooler fluid come out of the bottom fitting?

Also thanks again everyone for the input!!

 

Exactly

 

Would a tranny cooler work best with a automatic? Or It doesn't matter with either a mannual or auto?

 

There is no pump in a manual trans so you cannot have a cooler.

 

okay.....thanx.

 

I wonder why you can get a tranny cooler with a manual in some vehicles, but not all?
