Problem fixed: Would not stay in gear

Hydraulic assisted shifting pump snap ring fell out of the check valve witch allowed the gears to not mesh fully wearing out the shifting selector gear and forward and reverse matting cogs. Some welding and machining along with parts from Crowley and it's going back together nicely.

Allways provides an excellent service at reasonable prices. Will certainly continue to deal with this company.
