Yet another fun post about a 14-19 Silverado with trans issues, who would've guessed!? I now rely on your help wizards of the internet to potentially enlighten/suggest to me my options.
Specs;
2017 Chevy Silverado 1500 LTZ - Crew Cab Short Bed
5.3L engine with unfortunate AFM (lifters currently on their way out but lets save that for a future deal shall we? *cough* AFM/DOD Delete Kit recommendations welcome)
Hydramatic 6l80 Transmission
4 - wheel drive
82,****** miles
Up until (3) days ago the truck drove relatively normal, slightly rough idle and super occasional noticeable misfires. Also at speeds of 65-70ish I get some good shaking of the whole truck which I have not confirmed but attributed to needing alignment done,(tires were rotated about a thousand miles ago and that's when the vibrations occurred, had tires balanced but no such fix.) Anyways, no hard shifts, no overheating (trans temp 190 and under) nothing, until this last Friday I get a whirring noise suddenly I notice while driving. I drive approx. 100 miles total on Friday and the noise is accompanied with what feels like the most minor drop in acceleration but almost indistinguishable from a light misfire. Saturday morning I turn the truck on and the whirring noise occurs while truck is in park warming up. I go to put it in drive, get about 6 feet, and then the truck slips out of gear while in drive. I stop, turn the truck off, wait about 5 minutes, turn back on, put in reverse and successfully back up my driveway that previously traveled 6 feet. Again whirring noise occurs from underneath truck right at transmission bell housing while in park, so I shut off the truck get a buddy over and pull off the transmission pan.
Magnet is covered in metal shavings, quite a good amount in the transmission filter, nice chocolatey transmission fluid with just the slightest tint of (I used to be red.) Can post a picture tomorrow perhaps.
After much research I have learned it is the torque converters that goes out on these trucks and sends the shrapnel into the transmission gifting it the gift of early retirement. My warranty ended last month in November and a mechanic who seemed wise told me to get rid of this truck ASAP, and that when the transmission goes it is like a light switch, how right he was.
My question to you, wizards of the internet, is that what are the odds my transmission is completely toast right now as it stands? I am sure that metal shavings of this magnitude must mean some sort of damage at minimum, but considering other than that I have had no other direct transmission issue what are the odds the transmission has a few thousand more miles left in it?
If there is any chance I could even get another thousand miles out of it I would feel its worth getting a new torque converter and installing it in these hopes. Of course that comes with the fun of new exhaust gaskets as well plus like 2 trans flushes to clear out potential shavings etc but I am in quite the predicament as usual.
Also I understand that this is probably a very difficult thing to even answer as you dont know what the transmission gears look like etc, if there is any pics I can take or other info I can provide that might possibly help guide an answer that would be much appreciated. I thank you for the read and any and all answers that may be supplied.
