I have 97 sierra with the 4l60e transmission. It runs great but for some reason it won't move far. As soon as I start it up I can put it in any gear and it will go like its supposed to. But about 10-15 seconds later it will slip out and not move at all in any gear warm or cold. I can then shut it off and start it back up and repeat this. It will spin the tires but only for 10 seconds. The fluid is at the correct level and I checked the pump by checking the fluid while off then starting and checking the fluid while its running and the level goes down like it should. Please someone help me!

You need a scanner to diagnose this problem as its a computer controlled electric transmission ,

 

You need to see the shift solenoid data when this happens , sorry

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

      True. My statement needs qualification. "For a shade tree mechanic, re-assembling the front engine to achieve a rough baseline timing of 0 degrees, as is approximated and indicated by common visual indicator mark alignment, measured with a human eye capable of 20/20 vision *with correction, I am reasonably confident that I have followed the outlined procedures/ prescribed methods for verifying baseline timing."   😉   In the end, the computer sets the timing, it's continuously variable based on sensor input, and the distributor only has a degree or two of physical adjustability intended for dialing in the final setting for cam ****** once everything is back together. But even that final value is acceptable within, I believe, +/- 3 degrees.   I thought my exhaust project was going to be a bear. To my surprise, the old clamps came right off last night, and I was able to unbolt all the hangers instead of having to muscle the rubber mounts. The old cat is ready to slip off the factory y-pipe. The rest is ready to come out with one or two cuts, and I've got a fresh blade waiting. I love living where rust isn't a thing.

      I work at a Chevrolet dealership & hear it all believe me.  Just reads like there's going to be a fist fight over filters.  Can't get enough, continue!!

      Tire psi

      I just can't think of the exact term GM uses for that higher gvw package without looking at the website but basically sort of a trailering package and I imagine it may also have been created to skirt around the licensing fee differences between a3/4 and 1 ton that apply in some states although ironically I believe in some states its the reverse that a 1 ton is the cheaper truck to license over a 3/4 ton. It makes no difference here in Alberta but oddly enough a 1 ton through my insurance company is a bit cheaper to insure over a 3/4 ton as its based on the insurance statistics they generate.    For sure when ever you do have the chance to weigh your truck and to be fair, try to have the fuel tank full or nearly so rather than give yourself a false sense of the truck being lighter by having an almost empty tank.    In my other comment I was mentioning stock sized tires and partly in case someone was reading this and thinking they could lower their pressure down to what your aftermarket tires are able to do with your empty truck as that is a vastly different picture in the leeway you have to play with for running minimum pressures while remaining safe. I will say also that its easy to see from reactions of truck owners that may have been more used to owning a half ton in the past or a car and be it on a forum like this or in person etc that they get so wrapped up in that placard pressure sticker that they can't get their head wrapped around the fact that an HD truck due to how much it can carry can also vary the tire pressures drastically lower than those pressures ( typically more so for the rear axle on stock sized tires ) when empty vs some car that isn't made to carry much so the tire pressures can't be lowered since it needs almost that much pressure just to carry the empty car.    If I ever do find myself in the states with this truck, I will only be too happy to switch it over to the US measuring system as then I will understand all the dash readings. The only thing that is off for me slightly with US measurements is US miles per gallon as I grew up with the Imperial gallon and to this day up here anyway speak in Imperial miles per gallon ( I don't do that on this forum though as that would confuse everyone for no good reason ).

      Tire psi

      By jgaudet99 · Posted

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol
