What kind of spreadsheet? For shift map/points?

[b00sty]

yes sir, also convertor lock/unlock schedule

This is for 3.55 rear gears and 235/50/18 tires so MPH may be off with, but engine RPM should be correct.

6R80 rpm shift sheet.xlsx

s550 shift based on OSS, you can find the gear ratios in the transmission section, use the following equation to find the OSS you want:

RPM / Gear ratio = OSS speed shift will be commanded

So say I want to shift at 7800rpm:

1st gear: 7800/4.17 = 1,870 OSS
2nd gear:7800/2.34 = 3,333 OSS

There are like 10 or more tables where you can change the shift speed, base, sport, sst, snow, dirt, etc etc, these are the tables where you can set the OSS shifts speeds at. As far the TCC, from what I recall the stock tune wont allow it to lock until the top of 5th gear, you can use the previous equation to find the OSS by gear that you want to lock the convertor at then go into those tables and set the lock up OSS/gear

What are the chances I can get this same detail for a car with 3.15:1 gears and 305/45/17?
