I was driving my 2018 Silverado (~75k miles), was driving at low speed merging onto highway, RPMs suddenly dropped to zero, got no acceleration from the throttle, pulled over, turned truck on and off then ran fine for another 50miles before it happened again at a red light, no lights on the dashboard appeared, I want to assume it’s the transmission but any idea what else it could be?

Not following the zero RPM's, did the engine die? Sounds electrical, bad ground, bad battery..... Any CEL's present?

RPMs gauge dropped to zero, complete zero, as if the engine just shut off yes, but everything electronic was still on (stereo/ dashboard), no CEL’s present, I cleaned the MAP sensor, maybe something electrical?

Take it to a parts store and have it scanned, not all failures turn the CEL on. you may need a scanner that records so you can see the data when it occurs. Trans codes may not turn the CEL on but are still stored

      Gas Prices

      By richard wysong · Posted

      Question for you Grumpy, why is diesel so much more than gasoline? Seems to me that it may be slightly a little less refined than gas and it doesn't have 10% alcohol which presumably lowers the price of gas

      Transmission Temperature Hitting 220s

      Thanks, so being a different beast altogether, anyone know what the "optimal" temp is for the 10L80/90 for proper shifting?

      How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.

      Gas Prices

      By Grumpy Bear · Posted

      Out and about yesterday on a long Saturday drive I passed a lot of Shell stations. My preferred, so I pay attention. Lot's of small town Illinois so not six stations in three blocks like the city.    Everyone of them over a radius of say 100 miles had regular at $4.19 but one which was the one closest to home at $4.15. However Premium pricing varied greatly between 85 cents over regular to $1.50 over. I'm not counting the price of the station with the lowest regular so the reference is the same for the remainder and all within the same brand. However the spread discrepancy holds across all brands.     @txab, any thoughts on that?

      Future GMC Jimmy

      What are your thoughts? The Chevy Blazer relaunch was an epic case of 'lunchbag letdown'. Jeep Wranglers and Ford Broncos stick out like a sore thumb.    The AI photos do not look like a 'retro version', but shrunken Tahoes. Get away from the 'futuristic look'. I've seen two concepts. One had rectangular headlight like a Rivian and the other way too big headlights (similar to a previous non-Wrangler SUV) should include dual round headlights like the early version.   If not this would look OK   At least it has GM styling (albeit the K2XX) A lot of the images floating around look like Bronco IIs or the current Bronco. Looking at the Broncos in my area (central Ontario, it seems to be a mix of 2 doors and 4 doors, 'mall rated' to ones that could go offroad.    I'm sure a AT4 and AT4X RPOs could be outfitted similar to a Rubicon if the braintrust understood the whole offroad scene. Crossing my fingers that if it does see the light that the front air dam/bumper doesn't extend below the center line of the tire...
