Trans Cooler

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.

Ride Safe!

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

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.

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.
