My 2001 Silverado 5.3l 4×4 has 189,000 miles. Last week while driving at low speed there was a terrible metal clanking sound. I was not personally there to witness the sound but it stopped doing it and seemed to be running fine. A few days later I was in a parking lot and I stepped on the gas and the truck would not move. It acted as though the parking brake was on. I could tell the engine was under load but something was preventing it from moving. It eventually lurched forward and started moving. It continued lurching for about 50 feet and then all was fine again. I checked the fluid and it was right where it should be. I drove home and went about my normal routine for a few more days until yesterday. I (thankfully) only about 1000 feet from my driveway going up a hill and suddenly the truck just stopped. The engine revs but the truck wouldn’t move. I backed down the hill and was able to get part way up the street to my driveway but It wouldn’t go any further. I tried putting it in and out of 4 wheel drive to no avail. Finally I shut of the engine and turned it back on. Now it moves! That was short lived. It only moves for about 30 seconds or so after being restarted and then stops.
So, what could be the issue? Why would it work for a short time after starting the engine?
Need a replacement transmission? Quality transmissions are hard to find. Free estimate to your email.Here’s the thing, it could be, and most likely is, a case of a set of bad clutches and band, or it could also be a case of a torque converter with a bad set of hiccups. I honestly think it’s the first.
To explain, when your Silverado is revving to get into gear, a whole series of things happens in the transmission from the torque converter setting up the right flow through the valve body and gearing and then to the clutches/bands, the final stop before the tranny engages (like a manual transmission’s clutch plate/friction plate linkage).
I think that one set of clutches is definitely on the way out and the bands that work with it are also pretty sketchy, too. (They’d have have to since they have probably been working together since you put the truck on the road under your ownership.)
I don’t have any reason to think you have done any major work on the transmission because if you had had the work done, then I think it would have been in your complete description of the problem.
Of course, you can’t rule out the torque converter angle simply because a hiccuping torque converter may act just as you describe.
Have your technician take a look at the transmission to see what else may be involved. I think you’ll find that one or more of the problems I described is affecting the transmission. And, since the transmission will be open so you can have it diagnosed, have the technician obtain a rebuilt transmission, if you plan to keep the pickup on the road. I know it will cost about $3,200 with labor and all. But, once you have spent it, you’ll have a pickup that’s ready to do another 200,000. And, you won’t have to spend all the money that a new pickup requires (take a look, they’re not cheap!!).
Seriously, do have the rebuilt dropped in as I think it’s your best — and only — logical choice.
Let me know what happens, please, as I really do want to know.
It sounds like an excellent deal. Good luck and thanks for the followup.
