When I got home, I checked the coolant level and it was very low - hardly any in the reservoir. So, I took it back to the dealer the next day to get more coolant added. It has not fluctuated at all since it was brought up to the "cold fill" line - so that is good.

Last night when I was filling up with fuel, I checked my transmission fluid. I had been driving for 45 minutes before this, so all the fluids were at their warm operating temperature. The transmission fluid was reading in the (C)old hash marks - no fluid was on the (H)ot marks.

The radiator has provision for transmission cooling/heating, so when I got home I checked my receipt for the radiator replacement. It simply said (1) Radiator and (3) Gallons of Coolant. No transmission fluid was added to replace the transmission fluid that was lost during the radiator swap.

Has anyone else had this issue? Is this how Ford tells the techs to do it?

How many quarts of transmission fluid should I purchase to be able to fill this thing up? I was thinking 2 quarts should cover it. And does anyone know the exact part#/name of the transmission fluid that I need to get from Ford? ]]> 6.4L Power Stroke Engine and Drivetrain thw420 http://www.thedieselstop.com/forums/f35/radiator-replaced-coolant-level-trans-fluid-low-242523/ 5R110 Auto reliability http://www.thedieselstop.com/forums/f35/5r110-auto-reliability-242502/ Thu, 19 Nov 2009 04:28:19 GMT How are you guys liking the new trans?? This may be the same model # trans but from what i understand it has been revamped for the new 6.4.
I have been reading that is handles a fair amount 4-500hp w/o any problems so far.

I'm thinking about a motor and trans swap and i'd like the extra gear of the 5R110. PCS has a stand alone controller for this trans and destroked has adapters, therefore I was considering it.
Motor wise, the mechanics @ the dealership told me to stick w/ the 7.3 so I might rebuild or drop in a cummins. Either way I'd love to use the 5R110 if it has become a solid tranny.

Thanks in advance!

First of all, this is my first personal diesel engine and I’m no expert. So hopefully the great members of this forum will add their expertise if I’m not painting the correct picture. Saying that, I didn’t buy a F350 for its city MPG, I bought it to pull and it does that without breaking a sweat. I do love the truck, but it is the first vehicle I’ve owned, that I haven’t known down to the last bolt and if it wasn’t for the chance of voiding the warranty (and the wife won’t let me!), I’d have it running with a tuner the way I wanted it to run.

Posted on this forum October 29th
I have had three flashes. I had a second flash done in the spring (May?) and did like the shifting better, and my in town mileage went down. On Oct 20th I brought my truck in for a stuck front calliper and they said that the engine took a new update, wife picked up the truck so I didn't get to talk to the Service Tech. I notice that the truck is shifting earlier and not smooth, but the in town mileage is up about 2 MPG. I'm leaving on a 1000 plus mile trip tomorrow and when I get back I will have a better idea, because I took the same trip last month and had kept the data. I don't know what version of update was done, but I hope I'm going to like this one, the last one Regened too much, bad turbo lag, ran with higher boost, but the shifting was smoother and the MPG was down.

Well I’m back from my trip and went back to the Dealer because they didn’t correct anything and to get the paper work, so I could let you folks know what flash I got.

I asked the Service Manager for the paper work and it didn’t have any information which version of the update was done. He said that it just took a new update because they hooked up the laptop only because I complained about the last Flash in May and couldn’t tell me any more about it. My lack of people skill got the best of him I think.

The new flash is noticeable, when not in Tow Mode, it shifts up at 40 mph and 50 mph but it is not smooth, this I think is why I’m getting better MPG in city driving. Also the Regens are less frequent (Except when I burn B5, see below), but last longer. Yesterday I towed my 12000 pound trailer to storage and in tow mode it shifts smooth but any sooner, so I’m thinking that the shift pattern is the same.

I travelled 1638 miles not towing and I’d say that most of that was 80% highway with the cruise control at 65-70 mph. I used a total of 116.17 gallons (US) measured brim to brim. This averages out to 14 mpg (US) this trip, the trip a month ago I got 16 MPG and the same trip a year ago I averaged 17 MPG.

For my first leg of the trip I had fuelled up with 25 gal (US) BioDiesel (B5). There was a lot of stop and go road construction and a detour because of an accident. 30 Miles into the trip I had a Regen which I account for not having a Regen since the re-flash. And had two other Regens till my next fill up (Which I said to myself here we go, but could it be the B5?). All Regens lasted around 15 minutes. At 328 miles I filled the truck with 23 gals of fuel regular diesel fuel. After that the Regens didn’t happen as frequent, I say on average just over 400 highway miles where as before it would happen every 200 miles or less with the same driving. Once on this trip I drove 300 miles straight, highway, one Regen, Ford Cetane Additive, and got 16 mpg at 70 MPH, my best for the trip.

So not to drag this on (sorry), here is my thoughts and I don’t know what I believe.
  • The re-flash changed the shift patterns in non-tow mode and I think this is the reason I’m getting better MPG in the city, defiantly shifts up sooner,Regens less, but I was getting better highway MPG before May. It changed the Regen cycle to be longer and that’s why it is Regening less? And I’m not sure but the DIC MPG doesn’t seem to be accurate anymore with the hand calculations, I’ll have to do a few more calculations.

Have the problems with the 6.0 been resolved in the 6.4? I don't like the thought of buying a truck from Government Motors and like the extra towing capacity but just don't want a repeat. Also - I can't justify the cost of a new truck so the new 6.7 coming out is not an option. Any comments appreciated.

My F350 Job3 was brought in May 2009 with 12,000 mile to have the radiator changed this is after I had brought it in 5 times over a year to get coolant added and finally told them that I know where to add coolant, and wanted to now know where it was going. I brought it in the next morning and it took less then a day to change out. Since then the coolant level has never been at the level it shows in the manual or at the marks that are embossed on the coolant reservoir. I put tape on the reservoir to mark the level to keep my eye on it; the coolant level hasn’t changed in six months. I brought my truck in for 3 things and a stuck front calliper on October 20 (Which is still sticking) and mention that the coolant levels was low since May, but the truck hasn’t lost any coolant because I check regularly when the truck is cold (70 degrees). They went ahead and did a pressure test and said that I had no leaks! But the coolant level before I left the Dealer was still below the embossed cool marks. I brought my truck back to the Dealer last week because none of the things were corrected. They checked the coolant level and didn’t add any, because the Service Manager said that if they add any more coolant it would blow out the top of the tank. If that was true, when I’m pulling a 12,000 pound trailer at 70 mph in 90 degree temperature why does my coolant level just reach the cold engine mark. Sorry about the length and rant, but I no longer have faith in my Dealer. Because of my lack of people skills, I always get hung up on the small stuff.

At the time it seemed to be coming from forward of the cab and was engine RPM related. I wanted to try and figure out where this noise was coming from before I took it back to the dealer so I could point them in the correct direction. I beleive I found the problem. The "clicking" sound is coming from the manual 4x4 transfer case. I can stop the clicking by pulling slightly back on the 4x4 manual shift lever while going down the road. After I release the lever the "clicking" sound returns. I don't have any experience with transfer cases but I know a clicking or buzzing sound from manual transmissions was usually caused by a bearing or a "bump" on the slider where the fork contacted it. Anyone know if the fork, slider is the set up used on these manual transfer cases? Also as I go down the road and put my hand on the 4x4 manual shift lever I can feel a high freq. buzz. Will one of you guys with manual 4x4 let me know if yours is the same?

I turn off the tcs and that usually but not always stops the problem from recurring. After a few minutes, perhaps as long as 10 to 15 minutes the ABS light goes out and all is fair until the next incident.

One thing to note I had the venturi T from the factory not a recall fix.

For those of you that had the radiator replaced, how long does it take? I am at 33,000 miles and mine has started leaking. :nono: So I am going to make the appointment to get it fixed.

Where mine is leaking is on the lower drivers side at the seam where the aluminum is crimped to the plastic end. I just noticed it on Friday when I was getting ready to leave as I just loaded the truck with parts to go on a job.

Other notes on the leak is after I noticed it I wiped it clean and then drove it home and after 6 hours of the truck sitting - everything still dry. This morning go out to look at it and crap a drip on the frame horn. My thinking is when the radaitor is hot it's not leaking cause it is hot and expanded. When it cools the leak opens up.

This morning was a little different than other regens. It went into regen very shortly after first morning start-up, probably 2 miles down the road, truck not near full operational temperature. Approx. 29 degrees outside.

I get on the expressway and look behind me and only saw a massive white cloud of smoke. By sheer luck, my brother is going to work only on the opposite side of the freeway and sees me. He calls me and asked if the engine just blew or if I lost a radiator hose.

Anyway, the smoke screen lasted about a mile and cleared right up and the regen continued as normal.

I've had all the latest flashes done. 37k miles, job 3.

This just is scaring the crap out of me.

Is the fact that it went into regen with a relatively cold engine and the cold outside temp. the cause for the excessive smoke?

Pretty darn embarrasing.
