I've been doing a little digging about the 4L60E transmission in the '03 and '04 trucks. My take-a-way is that this tranny is pretty darn wimpy. Is this true??
Here's what I've found...
It doesn't take much of a performance increase before people start talking about tranny coolers. (OK, I can see a supercharger) Really? How much power can this tranny handle in stock configuration?
Putting in a Corvette servo raises concerns in some forums. Can that really do damage?
My hand held tuner can increase shift pressure. How much is too much?
The tuner can also turn off torque management (which, by the way, is a boat load of fun) but some forums say turning it off is the kiss of (transmission) death. Is the tranny really that weak?
I'm sure some or all of this may have merit if you're going pedal to the metal at every stop light, but for just fun, spirited driving, are these concerns valid?
I had thought that the transmission in our trucks was quite robust. But now I'm starting to wonder. Your thoughts???
