Welcome to GearSpeed and Thank you for your interest!

GearSpeed is a subsidiary of H&A Transmissions, Inc. GearSpeed provides quality remanufactured Manual Transmissions to Honda and Acura dealerships,

extended warranty companies and independent transmission and automotive repair specialists across the nation.


Through GearSpeed, we also offer quite a few Obsolete/Vintage model transmissions for those who still have their classic Honda or Acura on the road. They are available in both automatic and manual versions.  If we don’t have it, we will gladly build your customer’s unit in a timely fashion (pending parts availability) and get it back to you as soon as possible.


We have recently expanded our operations to include on-site lifts for those customers that prefer to have us do the installation on their behalf.
