For GM automatic gearboxes, the second number is supposed to be the vehicle weight rating, but what units? I noticed that Cadillac Catera (rebadged Opel) had a 4L30E gearbox, but the GMH Commodore Calais (very similar car) got 4L60E.

Hello, Have a '97 Buick LeSabre. As long as I can remember, they, being the dealership, and others, and the manual I think too, says to ONLY use GM Dexcool, and not the regular Prestone antifreeze stuff. Two questions, please:

Does someone know if anyone makes a full spool for the GM 7.5" rear end? I know there are several manufacturers for the mini spools, but can't find a full spool and don't really want to weld the rear either.

Recently GM has sold off various divisions in Africa, Asia and Europe and is closing the factory at Holden, which will become a mere badge. So have they just had a gutful of burning cash, or are they saving up to takeover somebody else?
