I've got a '90 Olds Custom Cruiser with a 455 in front of my 200-4R. I plan on using this vehicle as my daily driver, and I occasionally tow (~2000lbs) with it.
It has an extremely low stall of around 1200RPM, I plan on replacing it with the D5 from my GN when I get a new one.
Back when I still had the 307, I realized my shift points at WOT were around 3600RPM.
Originally, it shifted around 3600RPM whatever gear I put it in, even if I held it in first.
I wanted to raise the shift points, so my friend decided messing with the TV cable would change things.
Though he couldn't make it shift higher in Drive or OD, he made it so it would stay in first gear until I took it out of first. Later on, I read that adjusting the TV cable that way was a terrible idea.
After adjusting the TV cable as described on gnttype.org, I'm back to it shifting at around 3600RPM even if I leave it in first gear.
I now have a 455 installed, which is rated for around 100 more HP and torque. My shift points are now around 3700RPM and take a fairly long time. The shifts are VERY soft. I purchased a TransGo shift kit, but not only am I not sure if I'd be competent enough to install it, I've also read some things on these forums that said that the TransGo kit isn't the greatest of ideas.
What's the safest, reliable way to raise my shift points? I'm looking for something around 4500 or so. Do I have to replace my valve body?
Is the TransGo shift kit a bad idea, or would it help to make my shifts firmer and possibly prolong the life of my tranny?
How difficult and time consuming would the TransGo shift kit installation be for someone who's transmission experience is limited to a couple of tranny fluid/filter changes?
