Claim 0:
1. A method for operating a multi-gear vehicle transmission having shifting elements configured for engaging gears of the vehicle transmission, the method comprising:
decoupling a transmission drive input from a transmission drive output of the vehicle transmission when the vehicle transmission is in a neutral gear;
coupling the transmission drive input and the transmission drive output of the vehicle transmission when in a driving gear by closing shifting elements associated with the driving gear in order to propel the vehicle;
determining that a transmission condition with elevated drag losses exists when the neutral gear is engaged;
closing shifting elements of a forward gear to engage the forward gear; and
closing shifting elements of a reversing gear to engage the reverse gear, wherein the shifting elements of the forward gear differ from the shifting elements of the reversing gear by only one shifting element.
