$1250 is an expert rebuild price here in the Cincinnati area, full rebuild, flat rate including the entire pain in the butt it is to get that transmission out. Likely welding involved to cut open ends of cross member to get bolt out that will likely snap off, all of mine did. yes, should be all new solonoids included and a warranty of course. your looking for a shop that knows what a General Motors 4L30E is up front. Don't even mention is't an Isuzu. If they don't know what the 4L30E is, hang up and move on to next shop until you find one that knows that tranny. A good tranny shop will have lots and lots of table space because a total rebuild take alot of table space for a thousand parts, all to be inspected, measured, cleaned and or replaced. 4L30E was orginally a Chevy Chevette tranny that got the "E" as and upgrade and fitted to a 4WD all the time vehicle and it's grossly underrated by spec for our VX's. Spend extra $125-ish to disconnect your radiator's "intercooler" as I've seen the cut away of them and they are more likey to heat up than cool. An auxillary one just gets hung in front of your radiator and provides actual cooling. When those gears go, there is nothing to do. Putting in used doesn't get u anywhere either cause you don't know it's condition upfront and will end up in same boat later or immeadiately. Sad but we all do alot to preserve what will soon be 20 year old vehicles that are still distinct and loving!
