You don't want to engine break anything other than a diesel. Gas engines aren't built for it (not strong enough), and it generates way to much heat and stress. Thats what the brakes are for. Plus you add instability to the driveline train and tires and will lock it up.
I’m new to trucks but every sportscar I have had, I would be cracking down through the gears during braking before corner entry. Agree it destabilizes the vehicle so shouldn’t generally be done while near the limit of grip but first I’m hearing your perspective
You have big brakes in the cars for a reason, engine breaking continues to generate heat, which you should be cycling off during breaking periods because your off the gas, but still flowing air, your putting heat into the breaks at that point, giving the motor a break, then back on the gas.
The brakes aren't small, they lack the number of pistons I would prefer but they aren't small. First mod for me will be braded brake lines and high performance brake fluid.
Maybe I’m dense but I can’t picture it. What would you be doing after a long straight entering and through braking zone? What are you doing during the corner?
. Warranty doesn't cover neglegence or abuse. I get it should be right but fuck man why tear it up and make it worse. The more work they have to do the higher the chance of more issues down the road. He's lucky he had someone with him, I doubt they'd last out there very long by themselves

You get your braking in and then start your downshifts, that way your RPMS have dropped and your downshift are in the 50% range of your max RPM threshold or less.
Yes, rev matching while still on the brakes. Thats why your heal toeing. Your not transferring all that load to the drive train (transmission). Automatic transmissions are worse (Enter last Gen Z06 puking its brains out after a hot lap)There's a couple of ways to think about engine braking.
As @Variable knows, there's a reason that we are taught to use brakes only for for slowing down and rev matching on track (and on the road) with manual transmissions. Automatic transmissions and auto-blip manual transmissions (to some degree) take engine braking out of the equation ... sequentials are different and there's no need to get into them because they're not relevant to the TRX.
That said, having driven the TRX for a couple of hundred miles, I would personally discount the engine braking explanation for whatever happened here. Even in sport mode there's very little engine braking coded into the transmission. In auto mode this thing has enough weight generated inertia at 70mph will coast for ten thousand miles on flat ground.
Generally on street sports cars the downside of using gears to slow down, either for the pops/burbles or just because, is an issue that will affect the transmission over time, not give up the ghost at the start ... the only exception being manually downshifting into 2nd at 100mph which I'm not sure the programming won't allow this truck to do anyway.
Listen, we've seen trucks on this forum dump their oil because someone forgot to attach a hose ... this could be something similar that has happened here, or it could be a manufacturing defect in the transmission, or the whole thing could be a setup for clicks and Ford tribalism. The only way to really know is to have a neutral person look at the truck.
But again, in in my humble opinion although engine braking might have been a contributing factor, it is unlikely that this alone caused this failure on its own.
Ok. This goes against everything I’ve been taught on racetrack using street/racecars but I’ll take your word for it. So with paddles you are saying brake brake brake, downshift downshift downshift, turn in, maintenance throttle?
Exactly.
Nvm. I’ll figure it out. I think we are saying the same thing, just disagreeing with when to pop the downshift. I’ve always done it as soon as I wouldn’t be bouncing the redline
10-4. We are saying the same thing. Misunderstood what you meant
As long as your not suffering from any of the big singular issues, own the truck. Love the truck and have fun with fucker.
