1 of them is my car.... No hiccups, just Alpina TCM and I don't launch it out of 1st. Usually rolling into 2nd and then give it hell

Me either and I have 526tq not one problem. Its just a matter of time!

I reiterate here that not many folks have had a virgin tranny prior to Alpina flash. By that I mean they went heavy into engine mods, maybe tore up the tranny a bit. It may be the case that with simple things like fluid & filter, perhaps an aux cooler, regular dead stock internals + Alpina flash the 6HP21 will last a lot longer than folks think @ 500/500 and beyond.

Bottom line is there's no market for it. Especially with the timing flatline in some cars and forced early shift, it makes more sense if you're gonna go ST/VTT S3 to get an MT car and just upgrade the clutch.

I wld never by VTT S3s...lol

You know this, but staying out of huge boost down low really helps preserve things. Not that 3-4-5 pulls don't produce a lot of heat, but full dig launches beat the crap out of the trans. So that helps for sure.

I hope so. Ideally the following would hold into the mid 500s. Problem is none of us have any type of substantive data....All just speculation and a handful of anecdotes. But the below could be done for a not cheap, but not insane ($10K+) price.

Stock gearing, clutches, TQ converter, etc
Frequent fluid and pan swaps
Alpina TCU flash
Good transmission mounts
Dedicated aux cooling+more fluid capacity
LVL10 Valve Body

Anyone else see the thread title and have their mind drift to the far side of the gutter?

The high speed pulls, and then gear changes into the TQ midrange are what I believe are killing the higher power 6ATs. Like you said, we unfortunately do not have any concrete data and are just going off trans-failures/first hand experiences.

Only if you like trannies

Exactly. I am not sure why folks are willing to throw down $7k on an unproven build with no upgraded software, and none available, when this simple and sort of cheap approach hasn't been looked at hard. Not even sure all that stuff is needed. Start with good tranny, then Alpina, frequent fluid and filter, aux cooling, maybe mounts. Done. If it blows up try again with more stuff.

You could buy 6-7 or more used trannies for one Level 10 build, come on.

I believe 517 motorsports had rebuilt and upgraded internals(I believe) along with a stall. So in a sense a fresh trans(rebuilt) with alpina flash and 2 tranny coolers, I'm sure it had fresh fluid. Still didn't hold but that's 517 and not lvl10

I spoke to the person who had all the work done this is not he said she said.

This is the one that blew up right before an airstrip event after just couple of dyno pulls? Or another one? On the first one I read here 517 said they got "confused" between WHP and flywheel HP. Then never heard anything more.

It appears to be very important to reset adaptations and do the break in relearning period properly even on stock trannies, wonder if they just threw it together and went WOT on a dyno.

The one i'm talking about they new everything and it was going on a single. It was properly broken in and had the alpina flash 2 trans coolers and brand new fluid completely rebuilt, dude spent a lot. Started slipping around 550wtq. Not sure if it got any software updates though.

The 517 build was for Prem. He smoked it after a few pulls. The excuse I heard was the same as above, a mixup between WHP and BHP, which is either extraordinary mis-communication...or yea. I wasn't aware he had the Alpina flash at the time, but regardless it clearly was not successful. With that said, Prem was going for some aggressive numbers at the time so he wasn't pussyfooting around.

Yeah that is what I read here also, it had Alpina on a virgin rebuilt trans. Did not know about the coolers though. Since then I have come to realize how important reset adaptations is. Have no info as to if it was done on that car.

But if not it is the same as running 700WHP thru a trans that is setting line pressures and other parameters for less than half that. I can imagine that might blow something up real fast.

You'd need to do 50-100 miles slowly ramping up to WOT near the end to break it in right, and even then given the overall expense you might want to change the fluid & filter again after it adapts.

Prem's transmission was sent back and forth multiple times to 517 as they kept getting the torque output specifications "wrong" and the trans would be dusted after a few hard pulls. I believe it happened 2 or 3 times. I know he got tired of waiting for a solution for this platform so he moved onto another. All in all people were pretty upset with 517.

Wow that must have sucked. Would be ironic if all they needed to do was a proper Alpina flash + reset and couple hundred mile adaptation procedure.

As far as resetting adaptations I don't know if he did or not. Didn't realize you needed to reset adaptions. Should that be done after doing the alpina flash?

As for me I had Alpina done before RBs and never drove it hard until I got it tuned. I'm at 44k and I am due for filter and fluid change. Planning on slapping my single on keeping everything around RB power (which is very good) until something is figured out! I will also install a trans cooler. I like the one with fan that I saw on BB.
