My wife's 2008 chevrolet captiva sport transmission just broke today with only 36,000 miles. That model came out as the saturn vue xr I think in the U.S. and along with other models like the acadia and pontiac torrent have the same factory problem, the 3-5-R clutch wave plate breaks and causes everything else to fail. On top of that the chevrolet warranty here is only of 30,000 miles or 2 years and the repair cost is over 2000 dollars.
This is why I've never wanted to buy or own a 2000+ car from any manufacturer. They are more unreliable and the repair costs are way higher, I mean I spent 1,400 dollars to rebuild the Trans Am's 4L60E with race spec stuff including the stall converter, trans cooler, shift kit and clutches. Now we have to pay 2000+ just to rebuild this one to stock and hope it won't break again for the same reason.
Looking at my options here I'm even considering doing a 3800SC swap with the tranny of course and sell the 3.6 vvt engine. I wonder how hard would it be and if it would work. The current engine is supposed to put out 240 hp, but that's N/A and at this altitude I don't think it's anywhere near that and the mileage is not that great either, at least the stock GTP had better mileage lol. Plus I would add some stuff to the SC engine, like an intercooler and headers.
I know what it takes to make a 3800 work, but I'm not sure what parts of the SUV depend on the stock PCM that would no longer work.
