Just an update because i always hate leaving hanging threads.
So i marked my driveshaft and tire with a white marker and spun the tire one rotation, the driveshaft spun 3.75 times, so i'm assuming i have 3.73 gears in it.
I then messed with my B&M automatic shift cable, the instructions say to put the trans linkage and shifter all the way in low 1. then put the car into park and make sure it's still in adjustment. Well when i had adjusted that the line on my shifter that indicates if the car is on D or R or N never reall lined up. so this time i manually moved the trans linkage to P then R and N and D etc. to make sure that each notch lined up with my shifter mark.
I havn't test drove the vehicle, can't until Saturday, but my guess hopefully is i was driving in D2 instead of Drive.
