so, does anybody have a way of doing it using the factory fittings?

 

Sent you a PM for the info as well.Thanks!!!!

 

I was thinking of using clamps as well. Somehow I have to fit 2 tru cools, 1 for tranny, 1 for engine oil.

 

PM returned

 

Bringing up an old thread to answer some questions in here about the additional external cold weather bypass, which is not needed as the trucool 40K has it's own internal bypass. Roger (AKlowriderZ71) was actually sharp enough to read the box that the trucool comes in and post a pic of it with some good info:



Here's the thread:

Hopefully this will educate some folks before they go and spend the time and money to istall the unneccesary external thermal bypass

 

After driving my truck in cooler weather I think the internal bypass is BS. Now that Im running a tighter converter than I ever have(2400) driving normal in 45* weather the trans temp barely rises off 100. Everything Ive read on the net leads me to believe this is too cool. Maybe for the looser converter guys this isnt a problem around town but get out on the highway with the tc locked up and watch the trans temps plummet.

 

My hose barb and clamp setup worked good till this week when it blew... A blown tranny line will stop u in about a mile. Ask me how i know.

 

Yea, that is too cool...we've been having the same weather here but I've been driving the Blazer. Gonna take the truck out for a ride tomorrow and see what happens. I have a Circle-D 258mm 2B 3K converter though which will generate more heat than your 2400 (11"?). Curious to see what my temp gauge has to say. I know that on the cold mornings, it didn't move at all, but I only do about 15 miles of driving on the days that I take my daughter to day care, and about 5-6 miles on the days that I just go straight to work. FWIW, when I ran my PermaCool 17K tube and fin cooler with my stock converter and trans, with no bypass, my trans temp gauge hardly ever moved above the 100* mark in the dead of winter, unless I drove the **** out of the truck and drove it for a long time. Wish that my scan tool displayed trans temps...need tuning software...eventually...

 

Don't trust your gauge. They aren't very accurate. After I read your post, I datalogged my own truck, and checked with one of my customers who monitors his F150 with an Edge. Temps today were 30*F. After being parked outside for 9 hours, it only took my truck 10 minutes to have the coolant temp at 195 and the trans temp at 125. Mixed city and highway driving tonight on my way home, my trans temp stayed between 125-130*F at all times. Traffic was heavy and slow(slick roads), so there wasn't any romping on it. My F150 customer is Roushcharged with a TruCool 40k, and he runs around 140 degrees.

With HPTuners showing 130*F, my cluster needle was barely off the 100 mark.



Torque converter lockup is allowed around 77*F.

 

Ill check it the next time Ive got EFI hooked up, but either way 130 is still too cool too. Seems ~150-200 is the sweet spot.
