I rebuilt this trans 3 years ago.It is slipping.It started slipping at high rpms and then would catch after backing off the throttles.It now is slipping at lower rpms-1600-2000.After you get the boat up on plane its seems fine only slips when under a heavy load.It has all new clutchs several bearings etc.Could this be an oil pump problem?it was a used pump we put in.there is a leak on the coupling seal can a new coupling be bought.I keep an eye on the fluid level constantly so I dont think fluid level is the problem.any help would be apprecited thanks for your time
