I agree with Bert, but thought I should add this. You started this thread on 7-14 and on 1-17 you posted this in another thread. “I run a forum for diving with many professionals, and we would not allow such an attack. With that, I'm out of your special forum here. Nothing here I really need. Have fun. Don't be so harsh with the noobs.” Maybe that is another reason no one responded. I also see very few Hustlers and 95% of the time I have found that when I find trannies with internal problems, due to our labor rate and cost of individual parts, it is cheaper to replace than rebuild, just using your times I would estimate $400. To that you should add new filter and oil, plus our time to diagnose, write an estimate and discuss with the customer and test unit on completion. Now if I thought there might be a leftover piece in the unit, it means triple check and find it, can’t pray it finds the filter first. Plus, being a commercial business we warranty our work like this for 120 days. New tranny warranty is one year. You don’t have to worry if you are working on your own unit, but every good business person and technician spends extra time double and triple checking even the simplest things, because comebacks can be our kiss of death. People who come here ask the professionals how they would fix a problem and it would be very unprofessional for us to advise them to bypass safety and do questionable things. To 75% of people feel that people in all repair businesses over charge people and only go to them when “Joe down the street” can’t fix it. Do you realize how much it costs the business and the techs each year in tools, diagnostic equipment, update schools and seminars, to meet the requirements of each manufacturer to do warranty work and be the professional you go to when you can’t fix it. On this forum we just ask for a little patience and respect in return for trying to help anyone. I’ll bet the same holds true for your business and diving forum. Hope this explains why we a a little harsh at times.
