Tomorrow morning I plan on getting the truck up to temp and checking fluid. Couldn't today as I was alone with a cranky 1.5yr old lol

Is it in the same gear when it happens? It's pretty common for the 4R70W to slip in first when the bands get bad, then for it to be fine in 2,3, and OD. You can get around that temporarily by manually applying first with the shifter.
Wait.... you do have a 4R70, right?

Hahaha 2100, my black truck did the same thing. I dropped the pan, drained torque converter, and refilled with new fluid. It's still going strong with the new owner.

Well as I'm deciding which amp I want to go with... today my truck decides to slip out of gear TWICE while driving (one time at a stop light trying to go when green and the other time stopped and trying to turn left in front of traffic) also twice today it took about 4 seconds to engage into Drive from park... time to switch focus and get this figured out

Also I read through your post I believe... and I have the 03 so it sounds like I wouldn't have the TC drain plug you had maybe do a pan drop and if it doesn't fix it then do a couple more pan drops to make sure I get the tc fluid changed out too.
Fingers crossed it's just really low and I just need to top it off lol... could I be so lucky?
Also worried the PO never changed it so it's probably 202,000 miles old
