Hortons and auto transmissions

[Archive]

Pondering the effects of the Horton fan clutch on a 24-valve '01 auto transmission truck. Now, we all know the Horton is big $$, but it also reduces warm-up time, adds a little HP, reduces noise, keeps the engine at a better operating temp.

But in a auto trans truck, the fan will not be rolling around full-time pulling air through that aux trans cooler, not to mention the intercooler. So crawling in traffic just short of Horton turn-on, what's cooling the transmission (not counting the fact that the '99 trans-on has a bigger pan)??? Maybe a non-issue since the trans is not under a serious load, but I'd like to keep this transmission as cool as possible all the time. Of course we could add an electric fan, after having just moved away from the engine driven one #ad
. So what say you guys? J.

P. S. Any opinions on Mag-Hytec vs. whomever on better transmission pans? Thanks... .

Good post NTENNA. Since some question my reasoning I'll state it explicitly:

The Horton and Auto Trans are essentially unchanged since the '94 model year; therefore, the 'undervalved' likely have good information on this topic also. Consequently, I'm moving this to "Product Forum", 'product' since it references a specific product, the Horton.

For the record, I've owned both 12V and 24V trucks, so I know what's specific and what isn't. I have no problem with the author putting this post in the 24V forum. On it's surface, it appears to be 24V specific. Many folks who don't have six+ years experience with Dodge Cummins trucks think some things are 24V specific that are actually general. That makes sense, I understand, no big deal.

We're (moderators) here to help facilitate -- don't take offense if we move your post! (NTENNA, this isn't directed at you personally, just trying to 'clear the air' so to speak with others who are getting stressed over moved threads).

Excellent thoughts... never considered that one when looking into a Horton. Finally think I can help someone else for a change, instead of badgering everyone here with questions all the time. Anyway, The Horton system includes an Air conditioner relay to enable the fan while its turned on. Therefore, a transmission temp gauge and a toggle switch connected in parallel would be a very simple way to control and monitor the transmission temp. If you really want to get fancy, or have the "know-how", put a Thermostat style relay on the transmission. This way you don't "need" a gauge or have to worry about monitoring it. Although, installing a manual switch still might come in handy.

Still wishin I could put my M3's mile deep paint job on the truck. Or maybe I should wish to swap its perfectly engineered automatic. Or maybe... . Ah heck, Just wish BMW would start makin a truck using the ISB!

I have had the Horton for about a year nd a Half. I have found myself always in the habit of watching the guages, so when I'm stuck in traffic, I just hit the switch. Temps come right back down. The same is with the engine temperature too.

If you have invested the money for the Horton Fan Clutch, then I would suggest you buy the guage. It is the best piece of equipment you'll buy.

NTENNA,
I've had the Horton on a 98. 5 24 valve with the automatic for probably over 2 years now.

I've got a MagHytec transmission pan and with a transmission temperature probe in it. Since I've had the transmission temperature gauge, I haven't seen the transmission temperature get over 150 degrees (bearing in mind I've only had the gauge for about 3 months). I haven't done any towing recently, so I don't know how the transmission temperature will do there. I agree with Wade that if you see the temperature going up, you just flip the fan on and it should definitely cool down with the amount of air the fan draws when on.

I have had the horton for about a year. In warm weather- stop and go the trans temp gets to about 175. Being it is also cooled by coolant, when running that warm (coolant) it is actually heating the trans a little bit (I think). The fan cools things (water temp) but I see it is slow to cool the trans- there is a delay in seeing it. It may be the sensor location. I have it mounted on the dipstick in the "genos" method. I also later put on a mag-tech pan. I do not think it is a big issue
