While the subject is up...is there any difference in the van chassis TC's, or are they all the same?

 

Just one point.
I talked to a guy about a used trany last night. He wanted 1500 for it and he says the truck had 90K on it. He was offering a 90 waranty.
I advised him that I could get one rebuilt for less. He says most of them are repaired not rebuilt. They are just fixed enought to last thru the warranty.
He would never buy one,

 

That's not necessarily true. The torque multiplication factor isn't directly related to stall speed.
Ford specified higher stall speeds because manglement was unfamiliar with diesels and liked higher stall speeds.

Torque converters only changed with the engines, not what chassis the transmission was installed in. In any year all 5.4L converters were the same, all 6.8L converters were the same, etc.

I'm sure a cheap shop would do that. A reputable rebuilder would do a good job.

 

Yea you would think, but that would explain some of the under $500 rebuild adds that I have seen. $500 is about the low end cost of a rebuild kit.

 

Just to bring this back up, been going back and forth. Warranty, well maybe. Meaning he wants till June, He wants me to leave it there so he can do it on his own time. Meaning i can't watch. He got back with me two days ago, My niece was in the hospital having skull surgery, so e-mails went back in forth. I wanted a price out the door no surprises. He hasn't got back yet. Oh and he wants to change rear main seal and fly wheel. I said no to the rear main seal, but fly wheel I guess. My seal doesn't leak and don't want to touch something there's no problem with. For guys wondering, it's going to cost me minium $500.oo just to tow it there and rent a trailer. He wants two days to do it. I said okay on the two days but I want to be there. Oh first price for this wannaty, $3300.oo , that changed to $3800.oo plus $250.oo for fly wheel and rear seal. I have know idea if tax is included, that's why I want a out the door price. Still waiting.

 

....and I knew as soon as I posted that I was going to regret leaving out details. I have to defend my statement.

The reasoning behind my comment of using a higher stall-speed torque converter and the inherent reduction of input torque (ESPECIALLY in the case of the E4OD and 4R100) to the transmission to make it live in such a harsh environment (read: non-gasser) has to do with the torque curve of the 7.3L engine. The highest flywheel torque numbers occur between 1800 and 2000 RPM and fall off SHARPLY. You know what a torque converter's job is and how it's done so no explanation of operation is required. By keeping the stall speed high in the factory build two things occur: The input torque to the transmission is limited because the engine is well beyond peak torque before maximum fluid coupling efficiency and as a byproduct shift feel is softened for NVH. By using a lower stall-speed converter, while more efficiently using the engine's torque to effectively get the input shaft spinning against a load, more destructive force is taken on by the transmission because the torque converter is actually more efficiently operating in the engine's peak torque range. Once the converter clutch is applied though, no torque multiplication occurs and all is equal. This is the reason I attribute my transmission's longevity behind ridiculous injectors.

On a different note:
Yes, torque (for realslowww). The turbine portion of the torque converter will impart HUGE amounts of torque to the transmission input shaft and not actually spin (horsepower). Stall speed. No horsepower required here. Now, once power-adders have been introduced to the equation all factory stall speeds are null.

 

I am not telling you what decision to make, but if I was looking at a "warranty charge" of $4000, I would be telling your big boy of transmissions that there is no way. I can only imagine you paid ~$7000 for a bulletproof transmission thinking it would out live you and/or the truck. Now you are looking to pay more than half of that and have to wait until June...

It almost sounds like he is trying to push you away from bringing the transmission back to him, simply based on what you have written here.

I would be looking for a HD4R100 if I were in your situation, but I make mistakes everyday.

 

I agree Sous, I've been on here all day looking at options. Let you all know when I do, Lets see how crazy I am, but believe me every buddy will here the out come.

 

Am I understanding correctly? You paid for a super-built HD transmission with an ironclad warranty, installed by the vendor, that failed within 60k miles and paid the typical 2X premium price for that privilege...but now your "warranty" is going to cost you $3k with about $500 transport/return costs, AND 90 days?

I gotta be missing something or mixing something up?

I realize you are withholding the name of the vendor for your own reasons and timing and will respect that, for you to decide if/when you want to reveal it.

Really hope this gets worked out in your favor soon!

 

 

Read ExPaCamper's post above your's. That's about the just of it right now. So know, with what I went threw to date, returning it to him once, and not getting it repaired the first time, well. Have an appointment the 21th of March, he got back with me Monday by e-mail. We will see how this goes, but I am still weighing in my options. I'll put it out there when this is settled. Thank you for asking,

Chet

 

How does this guy justify putting a guy out over a month over a trans he built that isn't up to par? I am beginning to think he had been doing this a little too long with a little bit of an ego. Hopefully once you are face to face, he will step up. Ford Reman HD for the win!! If I had to do it all over again, after my similar situation and then some, I would go with a Ford reman.

 

I went back and looked...Im SHOCKED that John Wood's transmission is having issues at 60K and that this is how you are being treated. Don't get me wrong, anything man made can/will fail but the customer service is what gets me...

 

At just about 200k here, I am watching transmission threads to decide what will be next.

I do have a JW valve body. Can that go into and be an improvement in the HD4R100? It is supposed to include the "shift kit" and have the proper passages milled/opened up.

Maybe that is the winning combination? Ford HD4R100 warranty and availability and JW longevity and performance mod. Won't be as tough as the fully built, but if you are towing a sled or extreme...

If you crate up your transmission, you can check uship for anyone heading to the shop for shipping rates and bids. I've done that with a car (not the crate part, smart alek! LOL).

I REALLY hope you get squared away soon!

 

Posting to subscribe mainly, but as an owner of a JW transmission, and historically a JW advocate, I'm more than a little disappointed in how this is being handled. I can tell you that my experiences have been nothing but good, but thankfully I haven't had any issues with my trans since it was installed many years ago. I'll be interested to hear how this works out, but if it continues along the same path it seems to be on, I won't be recommending him any longer, and I'll hope and pray that I never have any issues with my own transmission. Good luck, Chet.
