Well, with the standard "opinion" disclaimers, the design isn't flawed
to the degree that you see catastrophic failures .... just premature
ones. A few sources cite insufficient lubrication to some bearing or
clutch...but if someone popped for a transferable warranty, you're in
like Flynn. What I do understand follows:

-- sensitive to proper transmission fluid
-- prone to governor pressure solenoid/sensor failures
-- [some models] prone to torque converter [clutch] failures, fouling
coolers with debris
-- the so-called "anti-drainback valve" catches torque converter
debris and clogs/sticks, blocking fluid flow to the transmission
"operating system"
-- people fuss about a lag after starting, then shifting from park
into gear, as this model doesn't circulate fluid through the torque
converter in park....generally caused by some worn [not to a fatal
degree] component that I didn't bother to catalog in my head.
-- rebuild components aren't crazy expensive, but the O/D unit, which
does fail, comes in around 3 bills:

Now that I've done my share of raining on the machine, I'd like to
hear from others how they think a GC fares off-road.

My '96 5.2L would get 20mpg on the highway. That was with the
Goodyear Wrangler AT/S's aired up to about 45 PSI. With a lift and
offroad tires it'll probably be a lot worse.

I've heard that it's so close that it's not worth the loss in power.

The full time unit is known for problems with the viscous coupler but
I had no problems with mine (130k miles).

I saw one that had gone off an overpass backwards and landed *** first
on the the road below. The doors would still open and close. Most
other cars would crush like a beer can. The flip side to lousy gas
mileage is that it's 4000+ pounds of crashworthy steel.

Only downside as a first car is that it holds so many passengers.
