Questions on Vig 4000 stall Hey guys i have some questions about my stall. Its a vig 4000 and it has really helped the car to jump alot better. but when it shifts at 6500rpms to 2nd the rpms drop to about 4500rpms which is killing my power. I talked to a guy recently who had a yank 4400 with bolt-on's and 3.42 gears, when his car shifts to 2nd at 6200rpms it only drops to 5600-5800rpm's??? O and my car has the stock 3.23's in it still. Why does my car drop so many rpm's???? Is it my converter???? Or do i need bigger gears??? any help plz guys???!!!!
I have the Yank PT4400 with 3.23's and I shift at 6500. My shift extension is ~5800 RPM's and it works very well. Obviously, each converter is different....I'd ask around and see if other folks with the Vig 4000 are experiencing similar shift extensions. If not, you might want to have it rebuilt, or swap to something new. Vigs are good converters, and I'm sure if there are any issues they'll take care of it.

Thanks guys for the replys, but i just watch the tach on the car and it loses way too many rpm's between shifts, loses toooo much power and it takes forever to build it back up. If it would only drop to 5800 rpm's i would love that. Is there anyway the shift extension's could be changed by tuning the car????
