My RV is a 1999 built on a 1998 Chassis. On my 3rd transmission, and the heaviest I have ever towed is a Ford F150 flat on all four, or an Olds Sihouette van four flat.

The transmission from what I have been told in this chassis application is the same they were putting in the Ford Excursion SUV. I was also told that there was no space to put in a larger transmission.

First one blew when the coach had about 6000 miles on it. That was a warranty repair. Second blew at about 35,000 miles. No longer warranty at that point. So I am on #3, with 62,000 miles. This one seems to be holding its own.

I had the flywheel go about 2 years ago on the side of I-95 in Florida on Easter Sunday. That was a treat. Before it went I had been hearing a whistling when the coach was at low speed or idle. I was convinced it was the transmission when it went, but luckily it was a relatively cheap $500 repair bill.

I also find that my coach hesitates and skips when I am driving in heavy rain. I believe this has to do with poor design on the coach, and the air filter getting saturated.

I am also considering adding an oil cooler when I do the transmission cooler.
