Hello John,
I had talked with you on the phone a few months back regarding the transmission noise in my 1755. To refresh your memory, the transmission made noise, and loaded the engine when the trans was in high nuetral. When the transmission was in the low nuetral everything was fine. I checks the lubrication pressure like you suggested, and it is fine. I pulled the top plate off the trans, and everything looks ok. When I turn the input shaft by hand everything turns smooth in both nuetrals, BUT I can feel that it turns a little harder in the high nuetral. Is there anything I should check before I tear the trans apart? I am afraid I will tear it all apart and still not find anything. 
Thanks
Mike Fyock
