Working to change my truck to 4wd and I have to pull the trans to replace the tail housing anyways. Would it be worth it to go ahead and install the PPE clutches and shift kit into the trans while its apart. I bought the truck all stock with 100k miles on it and its holding great currently I am just not sure if its worth it to go ahead an build the trans while its already apart then put in a converter at a later time.

Thoughts?

when that stock converter comes apart and plugs up the internal filter, those new clutches you put in will be toast.

stock converter doesnt like high line pressure, more than stock HP, and WOT runs....

Ok thats what I figured but I wanted to check to see if it might be worth it to do it while it was apart. Thanks for the info.

OK - you've piqued my interest. I wouldn't think a stall converter would be a good idea in a heavy duty pickup. Just what converter would be a good replacement for the OEM unit when the trans is rebuilt?

I know what pique means. It's the rest of it I'm having trouble with. The middle just doesn't make sense, and the last part is too broad of a question to answer without much more information. That would be like asking, "what is the best turbo to replace the stock one?"

The op asked about replacing his stock converter and was told it should be replaced before it took out the trans. I was wondering what converter would be best to replace a stock converter for a truck used for towing? I have a Corvette with a stall converter and the stall is good for a performance car, but would I want a stall converter in a 2500HD used for towing? My gut feeling is no, a stall would not be the best choice for that application. So the question is, if I replace my stock converter when the trans is rebuilt, what would be a good choice for a replacement. Another stock converter or something stronger? The truck isn't raced and it's totally stock with the exception of DPF delete and EFI Live DSP 5 switch.

After my original post, I read further down and it looks like many here are primarily modifying trucks for performance and not towing often, if at all. Maybe a stall converter is best in those applications.

I didn't mean to sound stupid or elitist, just wondering what a good replacement converter would be if and when I need to rebuild my trans. I hadn't thought about replacing the converter when the trans was done but maybe I should think about it before the necessity arises.

Stall is a function of a torque converter. A converter without stall is a clutch. For a stock turbo truck that is very lightly modified, a stock LML converter is a good choice. If you want to build the transmission to hold more power, most builders will recommend a triple disc with a billet cover, and should be able to recommend a good converter to work with your setup. It also depends on what type of characteristics you prefer. I typically use Goerend converters in my builds, and I would probably suggest a C or a D for you depending on the impression I get from you after we talk.

I think ur misunderstanding the term (stall) when u say stall converter.. All converters have a certain amount of (Stall) and depends on ur application such as daily driving,drag racing,sled pulling u choose ur converter based off the best (stall)for what your wanting to achieve but it's not just the stall you have to think about when choosing one that best fits ur needs. When u say u have a stall coverter in ur vette that word (stall) has nothing to do with it. Stalls very in range from a stockish 1800 to over 3000 rpm's for certain applications. How well the converter couples/flash and then the stall u want can b a very wide spectrum that has a lot of varabiles and that's what josh is saying. It all depends on what u wana do n what set up ur truck has... The best way to understand what I'm saying as far as stall is to get in ur truck or vette n hold down the brake n push the accelerator slowly down n watch ur RPM,s. When u start pushing thru ur brakes that roughly what (stall) ur converter is. Not an exact science but u get the pic. Lol

I tow plenty and very often on a 600rwhp tune ;). I also run a converter that is tighter and couples better than a stock converter but that is due in part to the power I'm at, turbos I run, and general setup of the truck

Josh explained it very well. Him and Mike gave good suggestions on converter choice.

That is why its called "The Limo". ;)

I have nothing to add about converters except to say the ML converter I have was a great choice.

I have a Gorend Billet Stator converter, I'm not sure on the stall but i can foot brake it to 22-2300 before it pushes thru the brakes. It drives 100% like stock when driving normally. I don't tow often or heavy, but have towed with it. I occasionally pull a Kubota tractor with a brush hog on a 18 ft. steel flatbed that was originally used as a skid steer trailer. It did just fine with that. :thumb:
