I have used FLT (talk to Chuck) for my Impala SS LT1 Level 4 4L60e rebuild in the past and was very happy with their work. They were only 10 minutes from my home so that made it easier... but they do have quick shipping.

Both the TBSS and the Silverado SS are daily drivers, but the SSS is the one with the RPM in it (the TBSS has a TVS1900 on it with a stock tranny). The SSS has a TVS2300 on it, a few thousand miles on the new transmission, no issues.

I would not recommend a handheld (other than AutoCal) to adjust for your transmission settings- not enough info to properly set it up.

EDIT- I was running a stock transmission (only a Vette Servo) on my 04 Tahoe 5.3L with 11lbs of boost. Was right around 550HP, was still running strong after I took the blower off and sold her.

Performance Automatic

I can't recommend a tranny shop for the 'Hoe, but since you live in VA, I will tell you to think twice before heading over to Performance Automatic.

I've got a Mustang w/ a pretty stock motor still (intake, fuel pressure regulator, exhaust - seriously, I can hardly call these mods since they are so mild) Took my good tranny to PA, they built it w/ a stall for $3k, and I reinstalled it. I drove it on the street (ie truly never raced it) and 6 mos later it died. They want to charge me another $1500 to look at it and tweak it with some HD parts...that I already paid once to have intstalled. PA has had pretty poor customer service from start to finish as well, but I chalked that up to just some cocky performance guys originally. I haven't been pleased with the product or the service that they have given me over the last year.

Hope this helps.

PS- I'm interested to see what you chose, as I have similar plans as you for a s/c and tranny to back it up.
