ok, for my GTP i have a 30 tooth differential (3.33 ratio) so i can change my 4t60e to 3.73 from 3.43. however, how far off are the shift points from stock computer calibration?

 

i want to do this, but im not sure when i can get programming done so its all correctly proportioned.

 

thanks for any info!

well, you'll be off by 11.5% so your shift points will probably be up above the rev limiter if you're at WOT... but staying off WOT you should still be able to drive it.
