Confused on Transmission Service

[mrmo]

6-7 quarts or liters will usually cover a average service. When I did my 2020 Gladiator transmission service, it took 6.5 quarts.

Thanks, i am going to start gathering parts

I disagree. The worst scenario for a transmission is frequent shifting and time spent out of lockup. Mountain driving, low speed commuting, and short trips

You aren't talking typical use, though - and I'd consider that borderline "severe use", especially the constant shifting/hunting of these in the mountains.
Lockup?
Think a bit - that's a newer thing, they didn't exist/were not common mid-80s and back, and yet they actually survived longer intervals, worse use.
These are far better engineered, superior materials and fluids.

People can do whatever, it's theirs, but the fear mongering that these will some how self-destruct if it's not done at under 50K typical use is just spreading fear without facts.

I'd love to remember the numbers I've worked on with far more miles, crap Type A and Type F fluid, no such thing as a lock up converter, only 3 speeds, how did we ever survive!
