Product Description
B+Ms 70255, 70268 and 70264 SuperCooler low pressure drop coolers reduce the risk of lube system failure. A controlled amount of ATF is allowed to bypass the stacked plate core, passing through a self-regulating orifice which monitors resistance to flow. Controlled by viscosity, the thicker ATF is returned directly to lube through two bypass openings in the stacked plate core. As operating temperatures increase, more of the ATF flow is directed through the core. Resulting in a highly efficient cooling technology that combines improved protection against lube system failure with the required levels of optimal heat transfer.- The most efficient coolers by size and weight available!- Much better cooling that ordinary 'fine and tube' coolers.- Rigid stacked-plate design is resistant to damage from flying rocks or other debris.- Fits all cars and light trucks with automatic transmission.- Pressure tested to 200 PSI- Includes installation kit.- Black finish.

Heavy duty November 30, 2008
Most people oversize these things. This one is built to be out front of the radiator, where there is little protection. It doesn't have the flimsy fins, it's alot more sturdy. Buy some those pre-drilled brackets and mount it at least a few inches in front of the radiator, that lets some cool air mix with the hot air from the cooler before it hits the radiator. I never liked these zip tie mounts since all the hot air from the cooler will heat up the radiator, losing some of your effectiveness and allowing dirt to build up between them that is difficult to remove. It's easier to mount it in series with the radiator cooler. If you do this, have the hot fluid go to the supercooler first, then into the radiator. Otherwise, buy some extra hose, cleaner, and some plastic nipples so you can seperate the tranny cooler from the radiator. This is the most efficient way of doing the job, but you need to know which hose is the pressure hose and which is the return. A good product, buy it.

Easy to install, effective August 26, 2008
This cooler does what's expected of one, I guess... not much to say about it.

It comes with 2 sizes of brass NPT fittings to interface with your existing factory cooler, if equipped. Supposedly there is an orifice bypass which serves to prevent overcooling, I guess that's cool except if you live in Arizona where overcooling doesn't really happen and instead you'd rather have all the flow you can get.

In case anyone wants a reference of functionality, I have a 2001 S10 4x4 with 4.3L engine & 4L60E transmission. On 110 degree days at 75mph my transmission used to run 240F, now with this cooler it runs about 205-210F under those conditions.

Excellent equipment April 25, 2008
Comes with all the hardware needed to install.
Good quality part.
This is a bit higher degree of difficulty than an oil change or brake job because some fabrication is needed, but a capable home mechanic should have no problems.

B&M 70268 Supercooler Review May 12, 2007
2 out of 2 found this review helpful

The B&M supercooler is worth the extra bucks over a cheaper version. I have another Jeep with a cheaper cooler that works fine but isn't built nearly as solid as the B&M. This thing looks bullet proof. I like the plate design which allows for mounting using the plastic straps through the radiator or if you want to build a mounting bracket there are holds and supplied bolts to do that. I like the low-pressure drop design as well which allows cold fluid to by-pass the cooler so that the tranny fluid isn't over cooled in the winter months.

The install took about 2 hours but I'm very careful with what I cut and where I mount it. The 4 feet of transmission hose that comes with the cooler was enough for me but that is mostly due to the way I mounted it. Mounting it in a different location would require more hose so I recommend that before you take too much apart you consider the location. Transmission hose can be purchased for a few cents a foot at an auto parts store.

In conclusion, I am so far very happy with this cooler. Once we begin pulling a trailer this summer in the heat the full truth will be known.
