does the computer have a programming input number for the rear ratio?? I sort of think it must in that my 1227730 SD computer says the car is going some 15% faster than it is....I have a 336 ratio and O/drive 200 4r the computer chip is set for a ~290 rear, no wonder the lockup happens too thinks car is doing 50 and it's only doing 35-40 or so....

second quesion, more minor, is about the temp thinks it'sabout 10F higher than it is....not all that important, but...wondering...

Please PM with suggestions, I frequent C3 section more...
