Excuse us? What are you talking about?

What I said was pretty clear? Give me a little bit and I’ll draw you a picture with some crayons.
Hang on. We will draw you one. BRB!
Looks like we just drew a picture for you.

Oh I know. Just dreaming of possibilities I suppose.

I’m skeptical to admit this but before I bought my 17 Ram, I had an 08 F350 Harley Edition that was Spartan tuned. It was nice to be able to choose when the converter locked up. Let me tell ya that transmission SHIFTED HARD. I mean, it shifted scary hard. That’s why it’s been so difficult for me to accept this 68RFE. I do like how my RevMax 550 shifts though but it was a long road to get there.

Agreed. I don’t always want it to shift like that but once in a while it would be nice.
... I too previously owned an 08 F350. It’s ok

This is my .02 on this subject. We offer locked shifts. The bottom line is as follow if anyone who know how the locked shifts actually work and are commanded they would understand why it cant be the route issue on the shaft breakage.
The folks who are telling that this is causing shaft failures are either A: not aware of how to initiate a true locked shift or B: spreading misinformation either intentionally or by no understanding what is really going on and ASSuming.
I'm not bad mouthing anyone here but my bet is if we told every tuner out there how to do it most would offer it pretty quickly afterward. I highly respect the guys who have came up with their own versions of it and some for the guys who are working on it.
The bottom line in some cases the trans can shift extremely hard when commanded to do so. locked shifts don't have to be brutal and not all locked shifts are equal. It all depends on gains/pressures and other such things. Heck if you move some things you can even inadvertently command the trans to be in two gears at the same time for a short time.
That said my 2015 has had locked shifts for over a year now (until recently we removed the moto and trans r to put something more interesting in) the stock 68 within it still shifted great and had no shaft issue. We have however seen trucks have failures of shaft 100% stock. our 2012 has 170k on a stock trans that has had locked shifts for quite some time as well. the 15 I'm not sure what mileage is but has been tuned from day one. Simply putting a label on locked shifts as (bad) isn't the right decision to make here as the majority use a technique that can and will not harm the shafts under decent driving conditions (don't get us wrong if you do reverse boosted launch in 4x4 on concrete it can be done) (or a regular boosted launch as anyone's tuning can do if not severely dated) . That said I'm out
I want to clarify what I said in this thread just so all that watch it knows...
I am not downing anyone's tuning. Matter of fact the ones who found the needed parameters for lock shifts are very talented. Heck once we have those things nailed down in Warp I'll probably run it on my truck.
The problem lies in what's best for the consumer. Locked shifts I'm sure will work fine for the educated driver. However, not everyone is educated or cares enough to know the potential impacts. It's no different in variations in engine tuning. We make our recommendations on the engine and trans side so that customers will be happy in the long run. Most folks rather not break parts and so we always advise on the side of caution.
A wise man once told me "the hotter you burn the light, the quicker it will burn out". This is a simple but profound statement that applies to modifying cars and trucks.
