4L60E weak?
I have heard that the 4L60E is a bit on the weak side.
Is this true and if so what would be best to make it survive better?
I have looked here and found all kinds of stuff but not real sure what to get and how involved some of this is.
I may run a little juice later on but the whole "may blow up your A4" worries me.
Thoughts?

Weak as water.
The 4L60E is notorious for failing. Usually the 3-4 clutchpack.
A number of things can kill it in short order. "Excessive" temperature, "excessive" horsepower and torque, manual shifting, or even if its the slightest bit low on fluid.
Of course "excessive" is a relative term.
Keep it cool, keep yourRW HP/TQ below 400 as 375-400RWHP is where they seem to eventually crap out. don't manually shift, expecially don't downshift it, make sure it's topped off and fluid is running out of the hole if you should ever refill it.

Hehe not looking for 600-700 hp. (yet) 
the car just has 2500 miles on it and all I would like to do is run maybe a 150 shot of juice on her without being to concerned about toasting the tranny.
would just the shift kit help?
Trans cooler?
larger servo?
Boost valve?
Or will I have to go into the trans to make it safer?

if your going to pull the tranny you might as well blow it up first!
serouisly beat on it and if it breaks , oh well then pull it. pulling and building the tranny is the same weather its blown or not.

Rodney built my 4l60 and is building a 4l80 for the 91 bowtie8 race car
All custom with a 9in rear gear
91 has the trans up front
If you Get a bullet proof trans the next weak link will show its ugly head.
RODNEY CAN DO THE TRANS.
