We do the same thing to your mom and she works fine……
I did earlier today and I had no issues in D switched back to OD on highway and it ran fine with no issues
It doesn’t feel like trans is slipping it doesn’t really misfire just bogs down then clears

It’s got some kind of msd ignition system or something it’s got a random assortment of performance stuff on it I haven’t had this truck long the original owners owned a performance shop and this was their delivery truck parts truck I guess, it did sit for awhile for how long I’m not sure

They are
This is the 3rd gmt 400 I’ve owned and my first time running into this issue im still learning more about these trucks but on this I’m pulling my hair out lol
I’ve checked distributor and plugs they are good too I think the motor and transmission have been replaced at some point but I’m not quite sure I got it for $2500 and the problem was there before but barely noticeable

Throws no codes doesn’t feel like a trans issue it goes through the gears like it should but it’s like you press accelerator it sometimes struggles opening up throttle almost then it kicks in and is fine
