Looking at all the posts about trans coolers for my 98 SB. Opened the Summit catalog to pick one out and noticed the "Automatic Trans Cooler and Filter, Heat Sink type" Has anyone had any experience with one of these. I was thinking of using it as a supplement to the original cooler mounted behind the radiator. With the limited space I have, it would be easier to mount a unit like that, then one with tubular fins and a fan.

Dean;

Jack (HogV8) recommended this cooler and he has a 2 speed; MOROSO makes a heat sink type oil cooler that can be mounted under your radiator so it gets lots of fresh air . It also has a built in changeable filter . SUMMIT RACING EQUIPMENT sells them . Part number is MOR-41200 .......Moroso 41200 cooler to me, and it has the replacable filter.

Another friend said that cooler could be mounted with 1 1/4" "P" straps to the frame crosstube just behind the radiator.

In hindsight, I wish I had purchased it for my 1 speed auto conversion. I asked for "the cooler on the new bikes" and got a rather large tube and fin cooler. Plenty large, but didn't know where to hang it till I saw LaMonts photo.

Hope this is helpful.

This is a B&M and the one I have used on several Boss Hoss's. The factory also uses this one.

Tranny cooler

I run the Moroso 'street rod' type filter (round with fins). It comes in different lengths, changeable 'magnetic' type of filter. I mounted it under the radiator and left the factory cooler on as well. No problem at 11,000 miles. Cheap insurance, it just needs air flow to work. If you run an air dam under the radiator, look for another mounting location.

All;

How about this one from Summit?

Brand: B&M
Product Line: B&M Hi-Tek SuperCoolers With Fans

Solid cooling power from B&M.

Keeping fluid temperatures down is a really great way to minimize wear and tear, and to prolong the life of expensive powertrain components. One of the best ways to give your engine and transmission that protection is with B&M's fan-equipped Hi-Tek SuperCoolers. These efficient coolers are built with B&M's favored fin-and-plate construction to handle tough cooling jobs; and they have built-in mounting brackets to make installation easier. On top of that, they're fitted with high-quality, 12-volt, high-flow fans that are controlled by a thermal switch that activates them automatically when fluid temperatures reach specified levels. These rugged coolers are pressure-tested to 200 psi and can be used on RVs, racecars, and high-performance street vehicles.

Jack ,

That's a great cooler if you can find a good place to mount it . Ty Cooper runs one of these on his big block and he has it mounted under the engine oil pan and he says it works excellent but hangs kinda low .

If you were to switch to the Oddessy PC 680 drycell battery , you would have plenty of room because this battery is about half the size of the stock battery and has no problem cranking the Boss . In fact this is what they put in all the new Boss's .

Jack;

I put in an Odyssey 925, with photo help from LaMont, so I should have as much room as his setup. Don't think their should be a lot of difference between my 97 frame and his, I hope!

As I do this install I'll snap lots of pics ( hopefully help on re-assembly) and launder soe thru someone to post for me.

Ride Safe!

Hawk,

One thing to remember, the transmission does need "some" temperature to operate at top efficiency. I believe Jim @ NESCO said the optimum operating temp for the trans is about 180 degrees. Below that temp you do not get good hook up due to fluids being to thick.

I think the cooler Adrian posted works for most single and 2 speeds. It is the stock cooler on the '03 and later bikes and I run a temp gauge in the trans case and have never seen the trans over 200. And that was in Sturgis, 90+ degree day, 2 up in Needles & Iron Mtn. Most of the heat issues on the tranmission was when the factory was mounting the coolers behind the radiators and drawing hot engine temps across them. I don't think heat has been an issue on the '03 and later bikes with this cooler.

This cooler mounts very nice on the front crossmember and stays out of the way. One other thought, I would not suggest a thermostat control on any cooler unless it is an auxillary cooler like Jack runs. The fluid needs to be flowing for the trans to work and cannot be resrticted or it is gonna build heat pretty fast. Doubt if a single cooler would than be able to 'catch up'. Just my thought.

The switch on my fan cooled trans. cooler is not really a thermostat controled switch in the sense that it restricts the flow of the trans . fluid until it reaches a certian temp . It is a electric switch in a in line fitting like the fitting used for the temp . gage and there is no restriction . The switch is set to turn the fan on at approx. 165 degrees fluid temp and off at approx 155 . As the fluid flows past the in line switch the switch detects the fluid temp. and turns on the fan . I'm sure the B+M fan cooled cooler works the same way .
