About GearSpeed Parts And Perfomance

Thank you for taking the time to visit our on-line parts store. We currently offer a full line of Automatic & Manual Transmission parts for both the Honda and the Acura automobiles. Although our inventory consists mainly of 1990 or newer model parts, we do carry quite a few older vintage parts as well. Therefore, in the event you do not see an item you are looking for we encourage you to contact us at:(909)476-7252 and ask for Bryan or Marcel.

As a volume Transmission remanufacturing facility, we continually accrue thousands of good used parts that may be purchased for a fraction of the cost compared to that of new parts for those that prefer to build their own. Remanufactured torque converters are also available for most all models. To assist you with the ordering process, photo thumbnails are included for part identification ease. Please note that many newer model units have “VIN” numbers, having these at the time of order will assist us in ensuring you receive the correct part needed in the event there was an update or a model change mid year.

Gearspeed would like to introduce the newest addition to our product line up; We are proud to say that after a few years and several attempts at developing a pressure switch that we knew to meet or exceed OEM standards, is finally here and available to the aftermarket. We have done extensive research and testing to ensure we had a tried and true component. We have not only worked closely with our parent company, H&A Transmissions, but we have also worked directly with several shops in our community. In addition, we have subjected these switches to thousands of hours of test cycles utilizing a solenoid test machine that we have modified and customized for our internal use. These are then monitored electrically for proper on/off pressures, ATF leaks as well as physical defects. Gearpeed Pressure Switches will complete your Honda and Acura transmission build with OEM satisfaction at a fraction of the OEM price.
