A TH350, depending on the kit may shift out of 1st into 2nd at redline or may stay locked into 1st.  Like I said, that all depends on the kit. _____________________________ Kyle- 04 Rainier My Restoration Projects Please Do Not PM for Tech Help (in reply to skitzobmxr) Post #: 4

A shift kit basically will readjust the way the tranny shifts... My friend had a kit on his 4x4 Blazer, and that thing shifted hard! It would easily chirp the tires going into second and it rode on 35's (in reply to skitzobmxr) Post #: 8

More than likely he just got one with a higher rpm limit. So with the old one you could've launched (hold down brake, rev up motor then let go of brake) at like 2200 rpms (don't know the exact number) and now it will be able to launch at a higher rpm giving it a faster and more powerful take off. _____________________________ Cars: 2000 Chevy Blazer 4.3L 4WD LT, 2004 Nissan 350z 6speed.

I believe the stock stall is anywhere from 1800-1900RPM. And yes, a shift kit shortens the shifts, making them more harsh.  A short shift is a transmission saving shift!  The longer it takes, the more heat and wear generated on the clutch packs. _____________________________ Kyle- 04 Rainier My Restoration Projects Please Do Not PM for Tech Help (in reply to aris_unlimited) Post #: 10
