Honda Pressure Switches

August 11, 2010

Once again as a team, Rostra has made an astonishing breakthrough in engineering.  We are very happy to introduce to the market several new pressure switches for Honda 5 speed transmissions.

For those of you who are new to the transmission side of things, a pressure switch in layman’s terms serves as a monitoring device that communicates with the transmission control unit to ensure that ample pressure is in the circuit that operates the clutch pack.  These pressure switches are mounted external of the transmission and replaced quite frequently.

Case quantity of 6.

Chrysler governor pressure solenoid issues

May 9, 2010

Be sure to check all grounds when replacing the solenoids and sensors on Dodge trucks.  This has always been a weak point in the vehicles electronic system and any poor connection in the system will throw a code that relates to a failed gov pressure solenoid or sensor.  We get calls on this nearly every day.  Double check the grounds and replace anything that looks questionable.  Adding additional ground points will never hurt.

Welcome to my blog

April 13, 2010

This blog has been a long time coming. I have been working for Rostra Precision Controls for over twenty years. During that time I have helped Rostra acquire numerous product and application patents, grown their transmission product offering to over three hundred active part numbers, developed and mentored too many young engineers and helped keep the production facility running smoothly.

With this blog, I’d like to share some of the knowledge I’ve gained during my career. Many of my posts will be taken from the many technical lectures and workshops I’ve been a part of. I hope this blog will reach those who have and interest in electronic automotive components and provide them with information that will be helpful in a practical way.

I’d love to hear from you and answer your questions as I’m able. From this blog, the best way to reach me is, or you can visit where you can see a video clip of the real me.
