I don’t really have any dmg or nests in or around the fuse box. Under it either. And I’ve connected a Bluetooth OBDII reader and it gives me engine speed and vehicle speed.

Yeah, this ain’t it. It didn’t fix it. Idk if the vehicle speed wire may be broken? I have no speedometer right now and the odometer doesn’t increase, either.

I’ve seen the connectors for the vss mentioned in a video before and I checked to make sure. Mine are correct. I also tried 4-HI anyway just to see and it didn’t give me anything. I’m leaning toward bad pcm, but I mean, it could be a wire from the ecm to pcm has a break in it somewhere? I’m...

Well, to update this. I’ve found that if I accelerate really slow, like keep the rpm’s under 2400rpm at most, then 9 times out of 10, it will shift. Also, my speedometer doesn’t work. It was bouncing now nothing. But I’ve also realized my odometer isn’t updating, either. I know the vehicle speed...

That’s all well and good, but theirs just never shifts into 3rd, at all. Mine eventually does shift. So.. ?

I need to add that when I am driving and have it just in Drive, it stays in 2nd, but if I manually shift to 3rd (I know it doesn’t actually mean shift to 3rd, just tells it not to go past 3rd), the truck does a pull like you can feel it tried to do something, but doesn’t, just stays in second.

Well, changing mine didn’t do anything. I’m so tired of this. Wtf could be the problem? 😔

ACDelco GM Original Equipment 24215111 Automatic Transmission Manual Valve Position Pressure Switch or look up the pressure switch manifold I think it what RockAuto calls it.

I haven’t tried it yet, maybe this weekend, but have you tried changing the pressure switch manifold? It seems to go by a few names. Someone mentioned this in a Facebook group I joined recently for these transmissions and it seems to be a possible cause.

Well, it was acting better this weekend with a new MAF sensor then this morning it was the same old shit. I’m wondering if there’s something wrong with the ecm or tcm. Idk.

But it does shift…

Hence the supposedly, lol. But I don’t think it’s a transmission problem. It’s not that it can’t shift, it’s that it won’t. It’s not being told to shift when it should be. I may replace the MAF and see what happens. It’s disconnected right now and is actually acting better.

So I completely reflowed the solder for where the A2 and A3 pins are connected to the main board. A2 is engine speed and A3 is vehicle speed, I think. Took it for a drive and they’re working now. Seems both of them had micro cracked solder joints.

I used my scanner (BlueDriver for the curious) and it shows rpm and vehicle speeds being reported. So I’m guessing the problem is all in the gauge. I think I’m going to remove all the solder from where the connector pins are soldered to the board and redo them. Or at least the engine speed and...

Pretty sure I have, he said he replaced the filter and fluid (I haven’t yet, but the fluid is pretty clean and the trans was supposedly rebuilt before I bought it..), but I don’t get any codes. Edit: unplugged the MAF sensor and the truck behaved a lot better. Still didn’t seem to want to shift...
