I own a 2007 GMC Sierra Crew Cab NBS 4x4 with a 5.3L with 28K on it. I'm interested in building/swapping the transmission for a built version better suited to frequent hauling/towing considerable weight and up to 500 ft/lbs torque. Bulletproof comes to mind. :) If I could do a modded 4L80E "affordably" and it not be a hack job, I'm game. Whenever my budget recovers from the transmission, I'll move to differentials and engine mods. I never race the truck or travel off-road beyond a boat ramp or to park near a trail. I plan to keep this truck for a very long time.

 

While mechanically inclined, I no longer have access to a lift (or a garage). I'm hoping someone might know of a reputable (and reasonable) shop to handle the transmission build/swap? I'm also looking to have a RC 3.5" suspension lift installed (both control arms, tie rods, u-joints). I'm in Western, MA (01085 zip) so I'm near Northern, CT and Hartford but willing to travel further for a talented group.

 

If anyone has recommendations for mods to build me a nice comfy bulletproof tow truck (short of suggesting I buy a 2500 or swap to a 6.0L e.t.c.) - I'd certainly love to hear from you. At this point, I'm fairly clueless with LS motors, GM transmissions e.t.c. Been busy racing Mazdas.. :)

 

New ported/polished heads, matching cam, intake manifold, headers/exhaust and ECU tune should put the 5.3 in the 480ft/lbs torque range without FI. Is that reasonable?

 

Thank you in advance!

dynamic transmissions in Branford is really good and well known. Cant give you an exact quote but it will be between $6-800 for the rebuild and comes with a dyno test for whatever hp you choose and 6 month warranty.

Hitec I believe it was called in East Longmeadow Ma. was a good transmission shop back a few years ago when I had to rebuild my 4l60e for my old s10 zr2. No way though they will do it for 6-800 dollars, not sure if you know the guy personally bird but not a chance are you going to get a rebuild done on even a 4l60e trans for that low, I think in 1998 mind you I paid well over 2500 for the rebuild and that was one of the cheaper quotes I received. I imagine it's only more expensive these days!

I was talking just to rebuild no parts included. You can get a rebuild kit rated for 800hp for about $700 and then a single disc stall for $800. That puts you right in the $2500 range for a full build.

      Trading 7.3 (Godzilla) for G.M.C gas

      By James Beyer · Posted

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.

      It has happened to me a few times. I carry a jumpstart-tire inflator with me.
