Diesel truck discussion

Brother has 7.8 gasser f350 dually; will tow 42k with goose neck.. why diesel which new requires DEF plus more upfront and need’s diesel mechanic?

 

Honestly, I don't know but it's much faster than the stock Garret because it comes up on boost pretty quick, yes I have a pyrometer and a boost gage. On a hard pull it will pressurize to 30 psi.

Interestingly, both my Kubota's are turbo charged as well but I never hear them, Must be the big mufflers kill the sound. The Banks stuff is not cheap but like anything, you get what you pay for.

I have his Trans Command on my E4OD as well and a B&M cast aluminum deep sump pan as well

 

That's the weak link. (E4OD)
Ford put a new one in every July for 3 years under warranty, then I removed the GN hitch and only towed a little single axle trailer....very carefully and rarely. Oh, and bought my F450 with a manual transmission.
Actually that was my 2001, not sure if it was the E4OD but my 97 a/t was about the same. This was with gauges for monitoring, Amzoil and auxiliary cooling.

 

They certainly weren't the best in stock form...the aftermarket builders can make them hold up pretty well though, even behind modded 'strokes

 

E4ohno!

 

The 97 that I sold to a friend put in a $6000 bullet proof in the line of about 6 transmissions. The heaviest towing he does is a decent sized Vermeer disc chipper and the motor was stock.
It's funny how Ford somehow fixed their transmission all of a sudden with the 6 liter.
How I would have loved to have the 10sp back then. It would have made the pretty "modest" 7.3 a great runner!

 

To be fair the 5r110 had a rough start with the snapring wearing a hole in the case.


Then when the 10 speed was introduced most customers didn’t understand and complained it shifted to much

you can’t win them all.

 

97throug atleast 99 maybe a bit further auto trany slash lube for rear main bearing on tranny , The bearing would grind its way out the backend of the tranny typically by about 125000 miles. don't knowif they ever corrected that. Wasn't anyway to correct the problem as stated by my custom tranny guys I use. they built race trannies for everything.

 

the c6 is not a bad transmission. I think it's comparable to the th400.
it's solid at least not great but not exactly weak. I wish it had a converter lockup in it but anyway..
The zf5 is a solid transmission as well. worst issue with that is the synchros wearing. I bring up the c6 and zf because both were available with the e4od back in the day.
I left the aod out because it was not for 3/4 tons and up.

 

Back to diesels being simple, they were. Initially. They were one of the last to get EPA'd to death. But when they did. Hold on. All that emissions crap to break.

Now this. The GM is the last one in half tons. Either they didn't make sense in general, or costs didn't make sense. Or maybe emissions cheating EPA hell? Maybe GM is putting them in everything while they can before the EPA squeezes the squeeze fire engines some more?

 

C4/C6 were good trans...but many of the other 3 speed autos were too...each brand had at least a good model or two....but I personally didn't like any of them...as far as how they put the power to the ground...very "slushy"

 

I know my truck has the c6, it's does the job and all but I have a zf5 ready to go in whenever I get around to it.
I think some of the slush comes from the vacuum modulator, trucks use a different one from autos.
When I bought mine I thought 2nd was gone from the trans. I could not tell at all, it wasn't until I put a real load on it did I actually feel 2nd kick in.
I'm told this is normal. It's weird going from 1st, quick 2nd, right into 3rd.

 

My 2000 f350 finally killed the stock 4r100 at 196k. Seems you either got a good one or a bad one from the factory.
New trans has a billet converter, GPZ clutches, and full trans go valve body and pump mods. Replaced the worthless factory trans cooler with a 26 row 6.0 cooler. My truck has simple mods. 6637 filter, 4" straight pipe turbo back, and Garret 38r turbo with either a 40hp tow tune or 100hp for every day driving. Hope the new trans lasts as long as the first one.

 

Are you sure it’s only 50%

 

Actually, my E4OD was professionally rebuilt by Fords SVO in Dearborn not long after I bought the truck in 97. It has all heavy duty clutches and actuators in it and it's never been an issue (gets the fluid changed every 2 years with the filter and the torque convertor drained.

Don't use Amzoil, snake oil. Just Dexron Mercon and a Motorcraft Filter. The 1-2 shift under full throttle is tight enough to light up the tires btw, not that I do it, but it will and it's limited slip.

I'd never have a Ford truck with a manual. Their hydraulic slave clutch sucks big time.

 

Buddy had that go out on his 2003 F250 7.3 turbo, a tad pricey to repair. Turbo went out on it also, got a kit for $10 fixed in my shop. worst part was getting that lastbolt/nut off one those how in xyz did they get in there in the first place things.

 

Curved Snap On metric box wrench. No issue at all (other than laying on the engine to reach it....lol

 

You forgot about renting the weasel to be able to turn the wrench.
