Richard:
Thanks for setting this and the Cummins forum...as well as the others.

Maybe we can all now learn more about their traits and idiosyncracies, modifications and any problems.

I have a 3060 6 speed. What mods if any can be done to this unit or is it best left alone. Mine came stock with Dextron III but I am thinking of switching to Transynd some day depending on the benefits and cost.

Any comments?

Thanks again. Another great addition to the forums.

Ken,

I just paid for our 2nd Transynd fluid change. The first one was done just after we bought the coach used at 25K. Like yours it had Dexron in it. They recommend the 2nd change after 25K miles, then they figure you have almost all transynd. Costs were $416 in 2005 and $426 today. Now we are good for 75K

, or I think it is 48 months, and then, that is a filter change.

I don't think Transynd is cost effective, but I feel better about it

.

I also changed the exhaust brake downshift from 4th to 5th. We have a much smoother ride!

Thanks for the forum

quickduk, since I do not see a locale in your signature, you will want to find a shop that has a transmission fluid exchange machine and have them pump out the old and pump in the new. Replace filters while your at it. I did this a couple years ago and could tell the difference on the first shift.

Richard;

Thanks for the additions to the forums. This makes IRV2 more valuable to many of us.

Tom, I believe you are correct, for cost reasons I went to Mobile One at half the price and even with a two yr change interval it will be cost effective for me. I expect to sell the coach sometime in the next five years.
