Simple to diagnose, get into the car… Put Reverse, Put Foot… If the car is still by the lift… You’ve got no gears!!! Put Drive, Put Foot… Repeat the last check. There are three reasons why a vehicle will have no gears:
No Oil, Broken Pump, Torque Converter, Worn clutches inside the gearbox. If the torque converter is the problem, it may have contaminated the oil and circulated through the gearbox causing further damage. This will need to be towed into Sparklight for a second opinion.
