Did you take the linkage off the trans yet? Do that and the try manually moving the trans shifters to neutral...you may need to jack the rearend up off the ground because you may need to turn the driveshaft back and forth to take tension off gears..but it should be fairly easy to get the trans in neutral. A cresent wrench on the shifters will make them easier to move..mr gasket shifters aren't exactly top shelf stuff but it should work..
