What made you switch from procharger to turbo?

I'm bored, so I will pile onto this pissing match. No matter how good you build the internals of a 4l60, at some point the tailshaft will rip loose from the rest of the trans. My neighbor did this twice in his turboed Escalade before swapping to a 4l80. Unfortunately the first 4l80 used a 4l60 adapter tailshaft to mate to the transfer case. This tailshaft also broke. The only way it held together was after removing all 4l60 bits from the equation. This all happened in a matter of months, which was mostly downtime. Since going to all 4l80 bits, it has only burned through one transmission in over 10 years.

I personally like having over drive on those long high way drives since it is a street car even though it doesn't get driven daily. Just like power adder choices every one has different goals. I certainly understand if you've broke a couple things you are going to be disgusted with it and not use it again. Personally I've had good luck with 4l60e's, but if I keep pushing my power level higher in the heavy GTO I'm sure to eventually have trouble and decide where to go from there at that time.

All these built autos dont sound cheap. And what oiling issues ? Never had any with mine.
Clutches can be hit or miss, but then it seems so can all these many parts/converters etc required for an auto.
Only issues I've had with the T56 is chewing up 5th gear on high speed runs, but even that was after 10 years of use.

The problem with autos, is they seem very task specific.
When I searched, it seemed difficult to get an auto that could be geared to run say 200+ as those with overdrive, said overdrive would not be strong enough to do this.
Which meant gearing it for 3rd gear ( or top in a PG )
But then that would mean very tall gearing for the lower gears. And all of this would make the car pretty useless for say road course type stuff.
6 speeds have potential....although most say 1k is the upper limit for these, and lack of standalone controllers meant it not viable, although there seem to be a couple on the market now, although no idea on their abilities.
But biggest killer overall is their size. They're ******* massive lol I'd need to cut and rebuild a lot of my car to fit one. Some day I might try a PG, as it's probably the cheapest and easiest unit for a test, but then a lot of people seem to say a PG is not suited to a heavy car ?
It really sounds to me as is manuals are a doddle by comparison. Almost fit and forget even if they are not best suited to drag racing.

Comes down to application. One size surely won't fit all. Trans, rear gear, tire, not to mention engine power band, etc.
