New Cooler...How Cool is Too Cool??

Follow your lines and you'll see it.
Are you folks with aftermarket coolers removing these things?

My truck has no problems (never has) locking up the converter or shifting into O/D straight out of the garage, I don't care how cold it is.
This keeps coming up but I guess no one is reading my post...there is no aftermarket cooler that I have ever ever seen with any type of temperature by-pass built into it. The Derales don't I know because I talked to their tech guys when I was shopping for one. I can also tell you, again, that this one doesn't and it's a factory ford cooler. The stock one that came off my truck did not have one either. I can't imagne oen being built into the cooler itself either. It would have to be internal to the tranny or installed in the lines somewhere.
Since this is a factory cooler that actually came stock on some trucks, some thought must have been put into it, I would imagine. Truck is running just great on these cold mornings (yea...58 to me is cold

The transmissions that used only the coolers built into the radiator didn't have a bypass. The ones that had an external cooler have had the bypasses, at least on the ones that I have seen.
Here is a link to a great cooler with a bypass. They are not "built in". I have never seen one that was built in. That would be much more difficult to do.

There is absolutely not a bypass built into the transmission.

The cooler is from www.getfordparts.com Just call the number and order up. Great customer service and everything. One penny shy of a Benjamin on the price, minus shipping of course. When I ordered mine a few weeks ago, they had quite a few in stock. Part number is XC3Z7A095CA. Brackets come installed already on the cooler ready to go in. Absolutely zero mods or alterations are required to install this sucker on a pre-'04 F-150. This is a factory Ford part and was the actual cooler that came stock on the '99 F-250 that was the same body style as our F-150's. You'll just have to adapt and rig up your own lines.

I am also running a set-up similar to what's pictured above. If I remember correctly, the gentleman who's awesome truck is in that picture (Tim Skelton) says that the SD trans cooler has an internal bypass. The passages in the cooler progressively get smaller from bottom to top. This would cause the fluid to go through the larger passages if it wasn't warm enough yet to go through the smaller ones. This would allow the fluid to pass through the cooler quicker and make it's way back to the trans to be heated.

Has anyone tried Troyers transmission cooler? It sounds like a pretty good unit and should be for $240. It's money well spent in my opinion if it does the job. http://www.troyerperformance.com/cgi...gno=PPI-ATCKIT

I have been having some of these same questions. I still have my stock tranny cooler in place (2007 5.4 FX4) and installed a trans temp gauge in preperation for my S/C. I have been driving around all winter and rarely see it get about 130. I usually have to sit in traffic or do a lot of stop and go to get that. The temps around here have been 5-40 deg F, is this normal to see below 120 deg F temps this time of year. I attached my sensor the line going into the top of the radiator, was this the correct one?

Remember, the photo is not my truck as stated in the original post. Just easier to post that picture since I never took my grille out for decent pics.
I used (all -6 AN) two 90* fittings at the cooler, two straight fittings where I adapted the braided line to the existing hard line, then the appropriate size hard line to braided line adapters for the "in" and the "out". Used about 7 feet of braided line. I'll get a list of the exact part numbers for all the fittings I used, but it's pretty basic. I used all Earl's stuff too!!
