Coadster32 793 #1 Posted February 4, 2009 Is there a valve or some metering orifice that regulates the speed of a Sundstrand hydrostatic tranny in reverse? I am plowing the driveway at work which is quite large, and it takes a little while because of the slower reverse. If I modified it, could I ruin the pump or something? :thumbs: Share this post Link to post Share on other sites
kpinnc 10,960 #2 Posted February 4, 2009 I seem to recall this problem showing up on the Sundstrand repair flow chart, but don't hold me to that... If you have the auto trans manual, I think there is something in there about it. I'll check tonight just to be sure... Kevin Share this post Link to post Share on other sites
Coadster32 793 #3 Posted February 5, 2009 Would I go to the Sundstrand web site to get a flow chart, and manual? A troubleshooting guide and manual would be great. Share this post Link to post Share on other sites
