Hi Maybe ignition switch has been reported on Mitchell Tech Net although GM has not owned up.
Seems ignition does not power up module and PCM at same time and trans goes into limp mode. Next time stuck in second check pink wire on trans connector if no 12v then switch off and on if trans shifts then ign switch.
Hope this helps
Thanks for donate

I have 95 Chevy K1500 Silverado that my Tach, Speedo, Gear Position Indicator and Odometers would not work off and on. When this happened, the trans would start off in tall gear making it very hard to get the truck moving. Mat and his techs were able to troubleshoot to 2 different issues. My issues may be different than other trucks with the same symptoms but the Instrument Cluster needed repair and Ignition module needed replacement. Mat took the time to Troubleshoot this electrical issue and was very fair on his pricing.

I fixed this myself. It was my ignition switch it feeds power to the trans fuse in the run position and gauges. Posted this to help someone else.

Hi there,
Just this morning I believe I had a very similar thing happen. Everything died, engine reved but it was not moving to well. I stopped and turned the truck off then on and the guages came back but tranny was still not right. When I shifted the transmission into 2nd the speedo/tach/gear indicator all died again.

I have an appointment at the shop tonight.I will suggest they consider the ignition switch. Although not quite sure if it is the same.

Thanks.

There is a little white plastic box located behind the glove box. This unit controls the speedometer in the dash, that might be affecting shifting. Try going to the salvage yard to find a replacement part.

The tachometer and the speedometer stopped working on my truck, and the transmission does not shift, it starts and stays in 3rd. Gear. I was told to check the fuses and they were alright.

Could be a problem with the VSS (Vehicle Speed Sensor) if the PCM doesnt see the truck moving it wont let the trans operate properly

Scan for codes it may be torque converter or a bad clutch so best to have a trans guy give an opinion on this

These are the kinds of things that happen when you try to Frankenstein a computer controlled car. You create a whole set of new problems. You have an operating system for one thing and now you have something else. All I can advise you to do is find an old Turbo 400 and then you are going to have to custom make mountings and driveshaft.

Transmission problem
1991 Chevy Truck V8 Four Wheel Drive Automatic 105k miles

Rear end was recently replaced with new diff, ring and pinion. After rear end work was completed, transmission will not go into gear and go forward when placed into drive. Will work in reverse, and placing into first gear manually, but will barely want to move in drive. All fluid levels good, transmission was rebult about one year ago and has always worked properly prior to rear end change. Yoke seal at drive shaft was replaced also when leak was noticed while doing rear end work.
