Is this Trans Slipping???
This is happening to me for 2 days because I've been towing a trailer with 4 quads and toomany stuff in the back with 4 passengers for 3 days.
What do I have to change and please dont tell me clutches because I have the red eagle clutches.
and can it be the converter doing this to my transmission?

Notice how it changes into third it doesnt do like that before it used to shift normal not it takes about a second to shift and forget about the park assist off and overspeed.

Contact Nelson Performance for 80e harnesses. Not sure of physical fitment (don't think that'll be a problem). Good luck!

Thats kph. 160kph=100mph
Ya these trucks transmissions were never designed for WOT 4th gear upshifts.
I remember that the valvebodies in the camaro/Firebird were different in the 4l60e's to allow them to safely perform WOT 3-4 upshifts.
there is a LOT more force on band when its applied at WOT into 4th than there is when its applied when shifting from 1st to 2nd gear. This due to the 1:1 up to .7:1 shift, compared to the 3.06:1 to 1.63.
I busted a 60e once doing a WOT 3-4 upshift. I only did it once and it busted the trans. And I am only talking about 200rwhp at the time.

Everything looked fine to me in the video. If you go from cruising in 2nd then go WOT right under your shift point, it is going to downshift and rev high quickly and then shift into second again. My nearly stock truck does the same thing. But, I guess there is something wrong since the tranny went out. You have bad luck with trannys. What broke this time?
