Help building a controller for hydraulic transmission

[Edenboy]

Hi everyone I'm new to the site and am after some help and knowledge.

I have a hydraulic transmission which usually works from an expensive microprocessor. Unfortunately the one on mine has been stolen so I'm trying to get it up and running without.

I need to control 2 coils which are basically forward and reverse. I believe they are 5VDC and were originally used with a pedentiometer to control different flows of oil through them. I have a PDF with some technical information http://files.danfoss.com/documents/11022666.pdf. The truck has 12v.

If anyone could point me in the right direction of some one who could make something up or help me make something up my self it will be most appreciated.

Thank you.
