Find a good trans shop now if it just started the shudder. My 2016 (same truck/trans as yours) did that for the first 60k of its life before coming apart.
I took the truck in with a couple thousand miles on it and told the dealer the TQ converter had an issue. Of course “cannot replicate” was the finding. Mine only did it under high load from a stop. Of course you can’t replicate that by driving an empty truck around the block…lol.
I’m all but certain the “shudder “ didn’t do any damage downstream until something finally came apart. Like I said, did it since new, never got appreciably worse, truck was horse whipped pretty hard in that 60k miles. Like bumper pull trailers in the 10-14k range flat peddled up n over the Cascades with 4-5000rpm grade braking comin down the other side.
Then one day it started acting up.
I never read about the issue much (company truck, didn’t care) but from a practical standpoint I’m 90% sure a new tq converter before it self destructed would have saved the trans without propagating more issues.
Hope this helps.
And the 4wd issue is likely unrelated (fortunately or unfortunately depending how you look at it).
Is your 02 an Alli or a 4L80? 100k miles maybe a bit more is a good/average lifespan for a 4L60/4L80.
The 1500 has a shudder/shake to it sitting at a light, but only sometimes. Shifting to neutral causes it to stop.
Transmission temperatures are pushing 190 just driving around, which is what's really bothering me. I never really paid attention before, but I can't remember it getting that hot, even towing.
The 02 is the Allison. 52,000 miles on it. Throwing P0700, P0843 and P0875 codes... All just say something amorphous about "low pressure" which is a "WELL DUH!" from me... It won't move!
Sorry to the OP for hijacking. I won't discuss further.
It’s all good. OP can get some real world opinions if anyone else who tows a 5ver with a half ton shows up. Guessing those folks are few and far between on a forum seemingly dedicated to recommending a dually for more than a full cart of groceries… lol.
Regarding your half ton, that’s the start of it. I bet if you hooked 10klbs to it and mashed the skinny pedal from a stop with no tire spin you’d feel it then as well.
I don’t have definitive data other than the same issue for 60k miles until she pooped the bed one day….not towing.
Regarding the Alli, unless mice chewed wires, likely a stuck valve from age/lack of use. 2400miles per year, average, assuming some years less or none as well is the definition of things going “bad” from not being used. Imo.
But there’s virtually no chance the trans is toast unless there’s more to the story.
Have you tried clearing the codes and see if maybe it was in limp mode and pulls its act together?
Sounds like you need a trusted intuitive Indy trans guy who isn’t trying to fund his coke habit or entire retirement off of just mkirsch! Lol. I know good shops are hard to come by.
