Hey i'm looking for some help on doing a transmission swap in a 2002 Chevy Silverado

 

Here are the specs of my truck:

-2002 Silverado automatic transmission

-4x4

-v6 4.3 engine

 

 

Could someone please let me know if I need to find a transmission with the exact year of (2002). Or will other years interchange with no modifications needed. I want to be able to simply swap them.

I am getting mixed feed back from the salvage yards around my area. Most of the are saying I have to get a 2002 transmission and others are saying other years will work just fine. Apparently GM changed the part number each year so it adds the confusion perhaps.

There is one salvage yard in my area that has a transmission from a 2004 and they are telling me it will work just fine. They said if anything the fly wheel might not work and they said they will provide the fly wheel with the transmission incase it doesn't fit the flywheel thats currently on my 2002 truck.

 

Thanks for any help someone can provide!

No expert, except at googling things, but it looks like gm specific tran model 24225957 was only for one year. The transmission is based on their std 4L60E transmission, so it might just need a different bell housing and torque converter set-up.

 

With that said, http://gmautomatictransmissions.com/transmission_applications.php suggests you could go all the way back to 95.

 

In any case, gm made some modifications over the years to some of the internals , especially around the valve body. You might want to consider doing these on the replacement tranny before installing. Not a rebuild, but would extend the life of what you put in.

Any 4l60e transmission from 99 through 2007 classic Will work .

 

It must be of the 99 nbs GMT800 truck or SUV.

 

All you'll have to do is change the neutral safety switch if the one you get is different.

 

Besides the switch everything will plug and play and bolts up as it should.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.

      This can be done.  It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness.   The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right     The problem with doing all of this?  You pretty much can't have any programming done to your truck that involves the cluster ever again.  The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with.  So it would be advised also to turn off over the air updates.   TLDR;  Should have bought an LT double cab?  You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.

      Yes.  The 2.7 Turbomax has Active Fuel Management.  It is NOT the same as the V8s.  Totally different system.     Here is an article from GM when the 2.7 came out explaining the cylinder deactivation and the valve lift system.  Starts at the section called "SCS Valvetrain":   New Turbocharged 2.7L 4-Cylinder Engine Powers Full-Size Trucks – TechLink         This is an internet myth going around.  It was alleged that some 5.3s had this mystical 8th digit of the VIN as an "E" which somehow meant it had a new one year only 5.3 that didn't have DFM.  The writer of said article and the person that made the claim conveniently can't count because they posted the VIN.  The 8th digit was a "D" which meant its still the 5.3 with DFM.  The 9th digit of the VIN was an "E" and the 9th digit isn't the engine code.  At all.
