MR 6 speed made stronger?
The transmission is not power limited its the torque that hurts it. Powerwise is also not what the downfall is on the MR. Many have drag raced it no problems, good amount even in the 10's. 1-3rd are actually thicker and stronger than that of the 5sp. 4th is the weakest then 5th and 6th. 95% of failures have resulted in overheating it on the track and losing 4th. Half of those failures were from people running crap fluid or the wrong viscosity. Good fluid such as the Amsoil MTG or Motul Gear 300 work great in the MR as thats what I use and am still going strong at 43k miles and plenty of track events with over 350whp. Yes its inevitable once you start doing serious road racing and have lots of power. A good tranny cooler will help and smart driving makes a difference. For 90% of the people on this site its fine...probably is the few that have had problems make it sound like its widespread plague of how bad the tranny is. Same thing goes for the GTR and many other cars.
Also take what you read with a grain of salt because half the people on this site get their statements from a friends friends dogs uncle cousins mechanic. Most have no experience with what they babble about. Find out what your goals are realistically and go from there.

Why were you running a cocktail instead of strait MTG if you don't mind me asking? It covers the correct viscosity range from Amsoil so diluting it just causes the fluid to shear at a lower temperature. I highly doubt it was your case though seeing as you had a good amount of torque.
Also no I don't have a tranny cooler. If I start road racing more I will invest in one. One other thing is to leave the stock undertray on. Few people that have sensors have logged 20+ degree higher temps WITHOUT it on.

At least someone has pic to back it up. The 6sp is a great trans, just not at the higher power/torque level. All i'm saying is that it's more reliable to convert to built 5sp. But in the absence of that, a trans cooler would be a good option for a little bit, plus a good investment if your road racing.
Just my opinion

I have since switched to amsoil mtg on the 5 speed..
I have 53K on my 6-speed. Have run multiple 11.1 passes this year, running high 11.8 times all last year. This spring it made 432hp/395tq on a dyno dynamics with zero correction (500+hp dynojet).
I run stock diaqueen fluid for the 6 speed. Is this not a good fluid? I have had success with it so far.

Some people, like myself, experienced 2nd notchiness/grind with the OEM fluid. I have been using the Castrol SynTOrq LT that I sell since 12,000 miles. It's a full synthetic exact 75W-85 equivalent and the notchiness disappeared overnight. I now have 110,000 miles on my car without a hitch.
For some the OEM works great. For others, like myself, the Castrol was the solution.

And yes, I am surprised how great things feel after 110,000 miles I <3 the MR 6 speed
Hey I get your guys' throttle body back soon - cant wait to put it on. 
I'll be throwing a BBK on my car soon; hopefully I'll be pushing around 400whp/350trq so I'll see how my 6-speed holds up!

Im running syntorq LT as well. Its not necessarily mopar stuff, they just happen to rebrand it because they use it in the viper and NV4500 trans. Same thing with Chevy, they rebrand it too. Works great and the notchiness is gone for me as well.
