Does that Jerry mod kit help? If you install a shift kit is it difficult? Do you have to take out and tear apart the entire tranny? Is the stock tranny good enough to keep using if you upgrade to a shift kit? Don't mean to hijack thread but this is something I to have been wondering about.
Thanks

The Jerry mod shift kit is the best mod for the money. You use your stock valve body, enlarge the holes in the seperator plate, and modify the accumulator pistons. Its the best and most of all, its safe for your transmission since it was designed by Jerry Wroblewski, an ex-Ford engineer who actually desinged the 4r70w transmission itself. The rest of the transmission will support it. Its not too difficult to install, however, you can mess up your seperator plate. I let a pro do mine....the second time. First time, I drilled the holes wrong cause I used a hand drill. I let this guy do it and he used a drill press. He also got it right cause he's done valve body work for years. He's actually a good friend of Jerry's. Anyhow, the Jerry mod is the best **** kit out IMHO. If you have any questions, feel free to ask.

i dunno, i launched from idle and killed a pretty heavily modded LS1 WS6. 
yeah thats the other thing... burn the tires up before you launch to get them sticky, run small rims, fat sidewall and bias ply DOT approved tires with little pressure in em, you'll hook like a mofo. Good luck driving on the highway though.

Even though I have 4.10 gears, I think that the weight of my convertible and my new Sumitamos help me to hook up. If I accelerate from idle, I rarely spin. The car just jumps out of the hole. Regarding traction control, I disabled it using my Diablo Predator.
I do and 14.1 is the time 97gtvert! GET A STALL IT THE BEST THING FOR YOUR CAR! 15.0 then put the stall in 14.1. Your car will be so fast than!Dark Knight GT said:
I see that you have the Precision Industries Stallion torque converter. From my research, this is one of the best. They claim to drop your 60 ft time by .2 seconds and your 1/4 mile time by .5 seconds. Did you find this to be true? Also, is it worth the cost ($695 plus installation)?

i launch mine at about 1000 rpms... just light gas pedal pressure while holding the brake. worked best out of anything I tried.
