Converters bad for stock 4L60E's? I ballooned my stock converter so I'm having a new one put in as well as having my 4L60E rebuilt while hes at it. Anyway the trans guy told my dad that if I went with a higher than stock converter such as (fuddle 2800) it would put stress on my trans since its not a built up 4L60E so my dad is real skeptical of me putting anything but a stock converter back into the car. Is this true?

You need an aftermarket cooler and possibly a shift kit. Most bolt-on cars are running this setup. You will be fine. Heat and HP kill these transmissions and if you aren't running insane amounts of HP you will be fine with just a cooler. What are your plans down the road? I have had my converter (vig 2800) for 6 years and 40K miles with no problems. I bought the converter used also. I bet you the guy who gave you advice works on older cars. 2800 is a small converter for these cars with lockup. There are some running 4000+ stalls with a cooler, shift kit and basic boltons with no problems.

Its bad because of heat, but a tranny cooler would help with that.
And actually Ive heard that besides the heat, having a high stall converter help absorbe some shock, like a pillow for the tranny..(but don't quote me on that)

I had 100,000 miles on my trans when I swapped it out for a built tranny. Shifted perfect the day I pulled it. 65,000 miles of that were with a 4200 stall. Installed a cooler with the converter. Cooler was well worth the $50.
Bone stock tranny. No shift kit. It was a stock internal, NA car so I didn't hit it with too much power.

A converter with a really high STR will put a lot more
input torque to the trans. Two ways; letting you get
up onto torque peak, and multiplying it more. And
often as not, torque management is removed too.
There is a limit to how hard you can beat on it.
Guys who run really high stall speeds also rev the
motor higher as a rule. That's also asking for it.
Hauling down the flywheel mass from 6500 to 5000
RPM against some strongly multiplied torque, is not an
easy job for the frictions.
