Alternator/generator/regulator Problems of GMC Suburban

1997 GMC Suburban- multiple engine & transmission failures. At 60,000 miles, vehicle began to shift hard. Returned to shop for diagnosis and repairs several times for work. Finally, while driving the vehicle in city traffic, the transmission failed compeletly. Required valve cover and transmission rebuild @ cost of $2,000. On December 27 '03, had to replace the radiator. On Jan 17 '04, discovered that there was no antifreeze in new radiator. Returned to mechanic who replaced the radiator. Said the intake manifold needed to be replaced. Cost: ~$600. Took to another mechanic for second opinion. Same diagnosis. Both state that gm is aware of both problems, however, they will not cover the costs of repairs or replacement. Additionally- replaced alternator two times; replaced water pump two times; replaced the master cylinder in fall 2003.
