Transmission Temperature

[Skywagon]

I just got back from the Ford Truck Service Center in Salinas where they only work on Ford trucks. (same place as before, except now their "Transmission Scanner" is supposedly operable). I'll bet you all a dollar that they are going to say "Yes sir, that there transmission meets all the parameters and is well within OFFICIAL FORD VAN FACTORY SPECS. Thank you for wasting two days of your time and don't let the door hit you in the ass on the way out"
On the other hand, they might fix it; and if they do, I'll say "I'm sorry I doubted you" and I'll buy any of you a beer that thought I was being cynical!
I should know something tomorrow, and will keep you informed.
Cheers
Bill

Bill,

I picked up my SMB yesterday and they said they ran every test they could on the transmission and could not find any problems. They could see where it had leaked fluid but had no idea why? .

I think my next step is to install a secondary transmission cooler. I am ordering the smaller B&M Hi-Tek cooler. http://www.bmracing.com/PRODUCTS/Hi-Tek ... ameter-fan

I decided on the unit with the fan because this will allow additional cooling even while creeping along in low range where there isn't strong air flow through the grill.

That's a nice Cooler.. I have the non-fan version and want to get that one..
I may be wrong but I think there is an option to add a gauge that measures the actual fluid temp flowing also versus what the ford built in themo reads..

With the fan coming on at 175 degrees, I guess it might not matter unless you really want to know the real temps.

NRL,

Thanks, This looked like the best all around option. I will post pictures when finish the installation.

They "reprogrammed" the transmission today and test drove it and couldn't get the temp above 184 deg. There're no hills in Salinas so I don't know what good that did, but they're going to mess around with it again tomorrow and talk to somebody at FORD and I'll let you know.

P.S. I got on a website today that talked about trans temps in F-350 & F-450 off-road fire trucks in New Jersey. They said that for every 20 deg. above 175 the life of the fluid would be halved.
Starting at what they considered to be normal (and I do too), 175, the fluid was good for 100,000 miles. At 195 it was 50,000, 215 = 25,000 and above 240, nil. From what I can find researching, 250 is too hot, although I can't get an exact temp from Ford. I've seen a little over 240 so I think that's close.
I like the idea of a bigger oil cooler!!!!!!!

John after you get that mounted please report back on where it fit best. I also have been looking to add one.

Where can we find definitive numbers for what temps are allowable and what temps are bad ?

I don't think Ford is willing to do that, for fear it will come back to bite them.

FWIW, my trans temp alarm (on my X-monitor) is set to go off at 230 degrees F. It has never gone off, but I keep a close eye on it if I'm towing uphill.

Herb,

We watch ours also, and I think it typically is around 190 to 205.

Hmmmm,,, now maybe we keep a closer eye on it....
