I'm about to buy a 91 suburban diesel with a 480LE in it.
I know TH350s, but not 480LEs. I'd be interested in hearing
about known problems, reliability, suggested upgrades,
etc., for this beast.
I will be doing light to medium towing with this thing, but
not more than about 5000 lbs.
TIA for any suggestion/hints/pointers, etc.,
