So, I recently started driving my dad's old 98 Chevy Silverado Z71, and I've noticed the speedometer is reading upwards of 20 mph faster than I'm actually going. He said that he accidentally pressed the 4 Lo switch one time without following the proper procedure and ever since then it has been off. Can the four low gear actually mess up the speedometer or is something else wrong? And how would I fix it?
Greetings all. Looking for some advice on why I might keep blowing speedometer transducers. I've gone through two replacements and although they work fine for about 30 minutes, they eventually just stop and the speedometer fails. Any idea what would cause the transducers' to keep failing? Rebuilt transmission with new speedometer plastic gear in transmission. I'm at a loss.
Hi, I recently pulled my t-case and replaced the housing on it due to the pump rub issue. After re-installing everything was fine for about 1 mile then the abs light came on and I got "service brakes " message and my speedo quit working, which also causes my trans to shift hard and erradictly . Long story short.... I've checked all the fuses , replaced the speed senor in the t-case (as far as I know this is the only one the truck has , it's a base work truck trim) and the wiring harness to the t -case and speed sensor, and no dice. The only codes that it is showing on the reader at the local Oreilly's is mass airflow and knock sensor. 4x4 still engages fine, the motor in the front axle works too. Btw, It's a 2003 2500hd 4x4 6.0 Silverado base work truck. If anyone has any info on this matter that could help I would sure appreciate it , thanks.
Has anyone else experienced any shifting issues on their 2019's? The big one I seem to get a hard shift point around 2-4k RPM coming off a stop under light gradual acceleration shifting from 1st to 2nd gear. It's fairly random but seems to be more common after the transmission heats up 150-160 degrees or more, though it'll happen cooler too. The other is when feathering the throttle in traffic the downshifting seems a little harder than it should be, not as hard as the upshift and it doesn't clunk like my old 16' but it's a feeling like driving over a small bump occasionally but it's happened enough while watching the RPM needle shift to think it's not just the coincidence of running over a little bump. Typically during low traffic speeds < 30mph.
All in all, the transmission is a vast improvement and is way smother compared to my clunky 2016 5.3L 6 speed Z71 which I traded in with 35k miles after valve sticking issues and a transmission rebuild replaced a fair bit of the transmission (torque converter, valve body, transmission pump).
I cant tell if i'm just sensitive to the transmission or if I have something worth pursuing, service department says to give it 1500/2000 miles while the truck is "learning" as mentioned in other threads, I currently have just shy of 1100. After that I dread the "normal behavior" discussion.
Overall it's a great truck, really smooth overall and a beast on the open road, in fact it's so smooth most of the time I think it might make the slow speed hiccups seem worse than they are. It's just a concern knowing that if it starts shifting issues at 500 miles, what's it gonna be doing at 20k miles etc..
Thanks everyone for reading! What's your experience?
