    I just got this truck less than a week ago but I think I might be detecting a light shudder in first gear during acceleration. Like around 15-20 mph and say 1,500ish RPM. It's not bad at all but at 52k miles maybe it's just due for a flush and new tyranny fluid.

    I'm tardy in getting the rig into get a rotate and balance and wanted to source the good minds here for some knowledge of any known issue before I ask them to specifically check it out.

    Side note, what's the best granny flood (tranny fluid) to run? Thanks!

    Ahhh autocorrect. You missed the "tyranny fluid" as well! :)

    Yes, about a 3" suspension lift.

    Could it be your driveshaft angle? I’d try a cheap carrier bearing drop.

    Doubt that could be the issue as leveling kits don't have the bearing drops

    UPDATE

    So I had the transmission serviced at the dealership about 2k miles ago and gave it a few months to see if it worked out the issues in the OP. Not so much, and I'd be curious to know what anyone might think the issue is. My plan is to take it back to the dealership and have them investigate the issue as I'm at about 54k miles and want this dealt with before the 60k power train warranty is up.

    Off the line, I still feel a shudder mid first gear under normal acceleration conditions, dry pavement, etc. It feels like the rear tires are breaking traction if I were hammering the pedal. Then, most shifts into second is harder than any other gear shift across the spectrum. It's not a bang, but it's 2x the buttery shift I feel across the rest of the tranny.

    Last, I was making a right hand turn in second gear yesterday and I decided to fully accelerate. It may have been due to a weak moment when I got cut off but that's a story for another time... When the truck shifted down into first during the turn, there was a quick slip and a sound similar to when the ABS engages. A crunch/grunt... Otherwise no changes since that happened.

    I'm thinking I have something wrong with the transmission and hope to hell the folks at Toyota find something and deal with it under warranty. A cursory DuckDuckGo search produced no real persistent issue across the fleet.

    Thank you, in advance!
