When will i need new torque converter/stall

Recommended Posts

So I have heard that I should look into changing my torque converter or stall. Can someone help me better understand what that is and why I need to change it? Also, maybe some recommendations. They are telling me this because I just got the truck 2 weeks ago but hopefully by next month ill have Intake, Headers, E85 and a street tune. Can't justify a throttle body or intake manifold, change my mind? lol. But I am new to all of this and they are saying maybe a 3200 stall will be good? no clue. TIA!!! Also, can someone point me in the right direction for info on drive shafts and when I need one.

So it's not going out but the people you talked to told you.  You need to get a new converter for basic bolt-ons.

 

If that's true you need to talk to new people!!!!

 

 

I have all that plus a cam and heads and still use the stock converter.

You don't need a converter, specially for those mods. A 3000 to 3200 stall converter will wake the truck up a bit, still it's not needed.

What are your numbers with that setup? Did you need a new driveshaft? I heard they can blow if you go over 100?

I think it’s more in the 120 range but yes they do go out.  But with my tires I wouldn’t go 120.

 

No numbers because it was remote tuned for the cam.  Then I added headers intake and Wideband later and made the adjustments my self.  It runs good though,  my wife has a Scat Pack Charger with the 6.4.  I raced her to 70 the other day only Launching in 2wd and had her by a truck until we let out.  That’s with 33 mud tires and 22x12 rims.

The root cause of these transmission failures IS the made in mexico converter failing and putting metal in the pumps and it turns to a grenade.

Really? Problem is in the design, not where it's made.

try the ZL1 converter from the older 6 speed Camaro, its $350 for 2500 rpm stall, beefier component than the stock truck unit

Yep.  Grumpy got that right.  Mexico has nothing to do with it, rather GM's choice of converter design.  They can make them in the USA, still a design choice flaw.

Yes sir, 24242552

Thank you. And that's a straight forward swap in? No other parts needed? Does it have 6 mounting tabs? Flex plate drilled for all 6? 

 

I know, lots of questions...

Good to know. I have the TVS1900, pullied to 10psi. Looking to do a small cam, lifters, rocker trunnions, headers and a bigger cat back. Probably going to have to drop in a LT4 pump and injectors at that point.

      Hi, 
      I have a 1997 c1500 ext cab with the small block 350 and a 4L60e. I’m replacing my torque converter but I don’t know what the original stall on the converter is. Some people tell me it’s around 1400 and other people tell me it’s 1650. Does anyone know the stock stall number? And the bolt diameter too please.

      Patient - 2019 1500 LD, 5.3, 6 sp, 7200 miles old, Covid-19 negative.  Symptoms - 2-3 second shutter / shake / rumble, during light acceleration, 30-40 MPH and low RPM.  Happens while both in V4 mode and while in v8 (manual w/ transmission set to L5).  I thinks its the torque converter, but surfing the forum I see this issue mainly referenced to 2015+/- K2s and I'm not sure if they changed the trans in the final years.  I'd appreciate either a TSB # or a link to another posting were I could find the TSB.  I'd like to be able to take to my dealer and say "HERE....READ....FIX" (politely).  Many thanks!

      When traffic light turns green, I kicked the throttle pedal, finally, this time, I got the power that a 454 supposed to give me, I almost cried.

      =======
      Months ago, I posted several topic (2 or 3) about it stall and knock sound under the floor, while cruising on highway.
      Well, the "highway" include GGB (Golden Gate Bridge).?
      94' 454 stall while driving and knock sound under the cab
      94'454 stall again, after change fuel pump
       
      Take note that I am actually completely a newbie, new driver (2 years), new vehicle owner, and new to America.
      So maybe some thing in my topic is wrong, but I don't tend to misleading.
       
      Shattered catalyst
       
      After the GGB stall, I found its power is weaker than before, and sounds like the exhaust is blocked, and when drive next to a vehicle or wall, I can hear air bleeding sound.
      Then got MIL code 32, EGR, however I can't find any problem on EGR system. This 454 engine use Linear EGR system, the valve is controlled by ECM directly, no vacuum pipe. 
      I tried to remove air filter, to make it performs better, then find the blocked-exhaust sound become louder.
      Then one day the stall happened again, I found the knock sound sounds more like opening a soda can.
      So I visited a muffler stop, turns out the catalyst is shattered, quite big loss. ?
      Since I don't have enough money for a catalyst, and it may be shattered again, so I asked them to put a steel pipe instead as a temporary manner.
      After that, the compressed air sound is disappeared, the blocked-exhaust sound is lighter but still there, and the performance is better but still weak.
            So shattered catalyst blocked exhaust, caused air bleeding sound.
            And caused extremely high pressure in EGR system, too much exhaust injected into intake manifold when EGR is open, caused ECM think EGR have problem, light MIL and sending code 32.
       
      Fired chip in ICM (ignition control module )
      The last time it stalls, at a quiet place, I finally figured it out that it feels and sounds like wrong timing, and when press throttle pedal, it back fires, and the harder press the pedal, the louder the sound is, very loud. And when it back fires, I can feel shock on throttle pedal.
      I told this to my mechanic, he told me to replace the ICM. He said back to old days, he replaced many of it.  He suggested me to purchase new one, because it's cheap, even from ACDelco, and this thing usually break down for years parked vehicles, vehicles in junk yard usually parked for years.
      I opened the metal cover of old ICM, find one of chips is black, oil or something around it is dark brown, the metal cover supposed to be glued to the plastic shell, but the gap near the black chip is open, so it's clear that the chip was exploded.
      After I changed the module, 3K+ miles so far, including 2 round trip from San Jose to Yosemite, stall never happened, I think the stall problem is officially solved.
            So the broken ICM caused wrong timing, and stall.
            "Knock sound" is actually backfire, the exhaust is under floor, so I felt it's knock sound under floor.
            Back fire caused huge pressure burst in exhaust, then transferred to intake manifold and throttle body via EGR system, caused shock on throttle pedal. Thank god this didn't ignite the gas-air mixture, or my trouble gonna be bigger.?
       
      Wrong base timing
      That's NOT all folks!
      I found it still very weak, on I680, the climb at east of Fremont, it even can't maintain 60MPH!  WTF??
      At this time, what I have done on it:
          Fueling system:
              New Delphi fuel pump, capable of over 60PSI;
              New fuel filter, ACDelco;
              Fuel injector, tested and cleaned;
              Fuel pressure regulator, changed new spring, 30PSI;
          Air intake system:
              New air filter, ACDelco;
          Ignition system:
              Distributor cleaned;
              New ICM, ACdelco;
                  Full assembly of distributor and ICM from junk yard as spare part.
              New spark plugs, wires and ignition coil, ACDelco.
          Cylinder pressure: I forgot reading, but within normal range.
       
      I pulled out the distributor for cleaning and ICM change reason, but when I put it back, I tried to find the timing mark. However, only engine block have the mark, the distributor don't have mark from factory, only a mark made by the ex-owner's mechanic, and it turns out it's wrong.
      So I tried to do base timing. I borrowed ignition timing light from my mechanic. But I can't find the "timing connector". At that time, I thought cold start and idle is running at base timing. So you guess it, runs over 20 degree ******.
       
      Then one day, I read my shop manual carefully, find out cold idle is NOT base timing, and only when the "timing connector" disconnected, the engine runs at base timing.
      However I can't find the connector, then after some dig on internet, I finally find it: inside the cab, passenger side, by the side of the blower motor, a single pin connector, tan with single black stripe lead, that's it. It's a bit far from "adjacent to the distributor".?
      Then I borrowed the timing light again,  do the base timing, hit the road again, the result, on I680, maintain 70MPH easily, like I write at beginning of this topic, I almost cried!
      Just recently days, it  even reached over 90MPH when climbing! Yeah it's speeding too much, but you know the traffic flow on highway is a bit crazy after reopen, probably due to people lock in their home for too many days.
       
      =======================================================
       
      So That's all folks, I currently focus on renew my truck camper, including solar panel, painting, bathroom convention, jack system rebuilt, then maintenance on the 1996 Ford F250xl, 350 engine, and convert to dually, create a "FAKE F350". ?
       
      Then come back, I found the A/C compressor is dead, my mechanic suggested me to get one from junk yard, because most of them from car part shop are rebuild in China, you know what, even I am Chinese, I always avoid "China".?

      Golden Gate Bridge, what a perfect place to have your vehicle stalls on.  ??
      ========================
      This is not the 1st time it stalls, see:
      94' 454 stall while driving and knock sound under the cab
      ========================
      Before this fault down, I have changed the fuel pump (thanks to <riverbanks>), the original one is weak, I can easily block the fuel pipe with thumb, I think it is almost fail. Changed a new one, very strong, I can't block the fuel pipe with thumb.
      ========================
       
      Model= 1994 Chevy Suburban K2500 Silverado
      Engine= 454 TBI
      Transmission= AT
      Fault down des. :
          Location= Veterans Blvd. tunnel NB, Golden Gate Bridge(GGB) NB, Alexander Ave. NB, Calif.;
          Transfer case pos.=2H
          Coolant temp.= around 210(heated up), normal operation temp., enough;
          Engine Oil= normal pressure, enough, just changed (incl. filter);
          Trans. oil= enough, just changed(incl. filter);
          Fuel= enough, #87 from Chevron or Shell, I only fuel my vehicles in these 2 brand, I've burnout old fuel, now is new fuel in tank;
          Symptom= engine stall, hear knock sound from under the cab.
              Veterans Blvd. tunnel: attempt to shift to N then crank, crank no start, stop on drive way (no emergency stop area) shift to P, crank, start, shift to D(O/D Off), continue the road.
              GGB: multiple time of stall, after some times of stall, found the engine sounds like intake or exhaust jammed, and very weak power.
              Alexander Ave.: stall when down hill with O/D off, but back normal later.
              Inspection at break down site: Air cleaner is okay, filter is new, fuel pump relay contact is okay.
              Inspection at home : OBD scanner get DTC 54 and 32.
      =====
      Current status=sounds like intake or exhaust jammed, and power is weak; when drive next to a wall or something, can hear the sound like bleed pressure of a tire, this sound can't be heard when the vehicle is not moving.
       
      I gonna check ignition system, incl. distributor, coil, spark plugs and wires, to check if there are any bad contact, but I suspect bad contact can't cause this problem.
       
      I am afraid one more thing have broken while on GGB .??
