how to lower WOT shift point

[forcefed3.8's]

I am installing my old GN 200 4r behind my turbo 301 in my Lesabre. What will I have to do to lower the shift points to 4500? TIA

You could swap the v-b and governor from trans to trans. Or just swap the gov and speedo gears.
The 301 may not have the torque to make that trans shift at the stock level either. Often, if the motor is weak, it can shift earlier.

what is the axle ratio of the lesabre?

It will have 3.73's and 28" tall tires. The trans I am using shifted at 5000 with the wastegate open under no boost, and 5800 under 22psi in my GN.

We're having the same problem with mine, Steve V mentioned it in the 3-4 Upshift thread, for my car actually. Currently with the new tranny that was installed which originally came out of Jeff's (FastregalWE2) car. His motor was made to rev up to 6k+. My motor can't handle revving to 5800, I need it to shift at 5000-5200 RPM. I believe it has the MCSS Green Governor in it. Sorry, but I have very limited knowledge about trannys, just trying to help Steve and I get it right for my car so I dont blow it up.
