Hi Guys,

I have all bolt ons except intercooler which ill put soon.

Is it true that only this is already too much for the AT?

No way I should add meth, or RB's right?

Thanks
Dan

not true

As long as your torque is under 500, you should be ok.

this trans. amazes me. i had to modify my vet trans to hold slightly over 400hp...that be said i would still do the alpine b5(i think) main for the quicker shift instead of clutches and bands slowly(sliding) in to gear changes...less heat build up which we all know is detrimental to autos.

510whp/500tq on mustang...auto tranny

One thing that people miss here is there are very few cars with high TQ (maybe none) that have run the Alpina flash from BEFORE they had all that TQ. So we really have zero data on what it will hold up to with a proper flash for mods, done prior to cranking all that high TQ through it.

Not True... Terry and Sick335 had high torque shift issues prior and the Alpina fix some of the issues they were having. Unfortunately I think Terry already had too much transmission damage and it didn't hold at Shift S3ctor early April... I haven't heard anything from Sick335, so it must be holding.

Judging from his recorded runs he was eating people up there on bone stock 6AT Step+Alpina flash. Sure seems like these things can hold in the 500wtq range, though we probably don't have the sample size over 10s of thousands of miles to say it with full confidence. What is certainly true is that people have been running maxed out stock turbos+meth+E50 and upwards for some time now, and outside of broken half shafts from wheel hop, there haven't been many "my diff just took a dump" type threads popping up.

Please re read what I wrote. They had high HP/TQ cars and ran their trannies w/o the flash for a long time. Then they flashed it. Damage may have already been done prior is my point.

Let's see someone take a fresh (stock) tranny in good condition with nothing but the flash and run it 500+ TQ see what happens.

[Wedge1967]

Well, I'm not sure what point you're trying to make. We know that it makes the trans hold more power with less slip, so why would it be any different for a new trans? If anything it would make it last longer.

I am above 500/500 and still holding great, no flash though....car is to old I also have upgraded tranny mounts if that matters.

Start looking for a newer valve body Rob. It's night and day!!!

Newer valve body? It'd have to be an entire replacement transmission that is post 03/2007 wouldn't it?

That's what I thought too?

Nope, who told you that? LOL... Order the transmission oil change kit from ECS Tuning.

Find a cheap transmission local on car-part.com.

Drop the pan, disconnect the MCM and drop the valve body. Replace with post 03/07. Recommend installing ZIPKIT prior to installation.

Once installed, flash with Alpina B3 transmission flash.

Rob, this is what the doctor ordered brother. You should DIY this when you do the swap.

Dude are you high or just being obtuse?

Unflashed stock trans + high TQ = bad, lots of wear/damage on internal components leading to possible eventual failure, many cases of this

Flashing this type of abused trans AFTER lots of TQ put through it, no conclusions can be drawn as to flash mitigating failures. Because the trans has been subjected to prolonged high TQ levels and may be damaged already.

However, flashing VIRGIN trans and THEN running high TQ through it, we have ZERO data on. It MAY mitigate failures. Flash has only been available couple of months tops whereas most high TQ AT cars have been high TQ for longer time than that (like Terry's).

Jeez. All I am saying is we do not know anything yet about how the Alpina flash does on a VIRGIN trans running high TQ. All other trans have been thrashed W/O flash, then flashed.

edit: Also as far as I know Alpina did not see the need to beef up 6HP21 internals on the B3, they are usually pretty crazy about hardware.

I have been running the Alpina flash and various incarnations of it since 2009. At 54,000km and around 30,000km on RB's my tranny has slower shifts and has been affected by the odd 470whp I use.

Disagree about the vettes at least a good friend if mine had destroyed 1 stock and 1 built Trans in his supercharged 10psi and meth c5 auto.

Can you elaborate? How much wtq are you putting down? I would love to upgrade to a set of RBs but refuse to until there is a viable solution for the AT.
