Which Torque Convertor To Get

Posted
  • Staff

After testing and conferring the consensus is my truck needs a new torque convertor.  The truck is used 95% of the time towing a 8,000+ pound 5th wheel and the transmission is basically stock.    Which brand is good and which type, stock or billet?  Should it be a single or triple disk?  High or low stall speed?  Any thing else you can think of.

    I highly recommend and use ONLY triple disc converters in every Cummins application. You MIGHT be able to talk me into running a single behind, say, a BONE STOCK 12 valve, but only because of the line

    That's 10 minutes from my house where I got a degree in construction management and where my wife retired from.   I had a BIG piece of cardboard over the dirt with a smaller piece of plywo

    Matter of fact thats what I did the last time. With idling I have been doing in this heat the 1200 miles a quart shrinks to 700 or 800.

I’m sure you will be happy with that set up,  If I was in a better position when mine went out couple weeks ago I would have gone this route. 

The Goerend pan is definitely a strong piece...instead of cooling fins it has a structural double 'X' across the pan from corner to corner and middle side to middle side on the bottom.  And in that part the aluminum is up to an inch thick which I imagine adds tremendous strength to the case and the transmission.

This is why I'm doing it.  1000 mile trip is a short one for me towing my 5er.  This spring was a 3000 mile trip and the past 2 years I did a couple of 7,000 mile trips.  I don't need any problems with the trans like I had with the VP44 in Riggins ID.

Jon says the Georend trans pan adds strength to the trans case which it needs after his mods are done.

I wonder if I could do input shaft myself.

You can if time and tools permit, in my case most likely the largest issue I have is dedicated time. Lack there of.

 

But depending on the miles you have on your trans, you pretty much are pulling the whole thing apart, if higher miles and never been freshened up, its one of those while your in there kind of things it spirals out of control easily. Not saying you have to go crazy and do everything top shelf. But a decent rebuild kit would not be a bad idea. 

 

One issue you will run into are the reference books are not always accurate for a inexperienced person like myself, there is no step by step guide, you kinda need to use the ATSG book, the FSM, and all help you can dig up for some of the stuff as it's not always accurate in the books.

My tranny is pretty fresh.  50k or less on it since I stuffed alot of money in it. I used to know what all is in it but I dont anymore. Most everything I couldnt afford.

I cheated put and didn't do a triple should have. :( since I did as much as I did

Yeah should not be too bad then internal wise, if you ever decide to do it I would share my mistakes.....I meant good ideas ???

Just to be clear, I do not make any mods during a build that weaken the case and make it necessary to have an aluminum pan. The design of the case, right from the factory, makes it beneficial to have some form of aluminum pan to add structure and stiffen the case.

Yes that is the way I understood it.... that a stronger internal build for greater towing capability and reliability makes sense for reinforcing the transmission housing as well. I am sorry Jon to have infered anything else 'Boss'. I stand corrected.:punish:.... Until Dripley starts his relentless pecking. LOL

No worries. I was just clarifying the reason that a good pan is beneficial. The need has always been there. :thumbup2:

Nice pallet, buid it yourself or is that a @JAG1 original?

If it hasn't been picked up yet make... sure you have good visibal shipping label...you don't want it to do a sight seeing tour all over all over the US. And  If me I'd use a magic marker on the wood. POC (point of contact)  your number.  And when you get tracking number, check on it daily

  

Ouch...just seeing that thing out of the truck makes me start sweating.  Memories...

Yes, it's been shipped and a copy of the bill of lading is tucked under the first strap and bar code labels are on each strap.

3X4 pallet I got for free from Escondido Volvo.  @JAG1 was busy building a house.

The next time I think about pulling a transmission on may back in the dirt somebody come by and slap me. :punish:

I'll be putting it in at a shop near here.

    If I know Daniel, he's got it insured for 50 grand :lol:

    Fine print, hidden in legal stuff.  If no declared value. Claims to be paid at 00.25 per 100 pounds of shipping wieght. 

    Then again is there really a difference of shipping to Portland Maine versus Portland oregon?  

     

    Ibmoble..everything will work out fine.  Your trans now in possession and control of America's finest.  Truck driver.
