To start, I have a 2002 2500hd 6.0 4l80e 4x4.

 

i can't shift down to 1 on the lever. I've been messing with it for over a week, still no luck.

so far I've changed the shift cable, shift control mechanism on the column, and the arm that attached to the trans.  None of these solved anything.

 

my next step is to change out the black box the arm attaches to on the trans, I believe it's called the safety neutral switch.  

Does anybody have any insight for me?

Is it a mechanical problem, in that you physically can't move the shift lever to "1" or is it when you move the shift lever to 1, it's not in 1?

 

And all the rest of the gears seem to work fine?

At the trans it can be shifted into 1, but not using the lever on the column.

the other gears are there, it's just not quite enough to catch 1 from the lever.

So if you can manually shift the lever on the transmission to 1, but the shift lever doesn't, then the problem would be before the transmission.

 

Maybe disconnect the shift cable at the steering wheel, and see if the shift lever can go into 1 properly.  If it does, then there's a problem with the shift cable (not adjusted correctly at the split point?), if it doesn't, then something is wrong with the shift lever/steering column.

Can't seem to get enough adjustment out of the cable to get it to snug up.

have replaced everything so far.

is this piece adjustable? The shift assembly mechanism??

My understanding is that the only spot that is adjustable is the midpoint of the shift cable, where the two halves of it join together.

 

Is that joint at either extreme (just barely connected or really close together)?

I know this is an old thread, but it's current to my issue. I am having a similar issue with a 2001 Silverado LT 1500.  I can either get 1st, or park. But not both. I have adjusted the "mid point" thread by thread. Am I doing something wrong or missing something? Have installed  new cables and new column shift mechanism.

I see this is old. But returning from a beer run I bwck into my spot no problem. I than go to put my 2003 gmc duramax into park and it won’t go. So like any well minded person I slam it down and slam it up lol. Now it won’t go into reverse.

My issue is not being able to shift from any drive gears to park and remove the key after shutting off the engine.  I was able to force the lever up and down until it went into park.  Worried if I got back in driving again it would lock up again.  Any thoughts about how to adjust or fix the problem?  Help !!

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

      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.
