Known issues on the 1992 C2500. The federal record for this model year holds two recalls. One describes transmission fluid forced out through the vent tube by heat the design did not anticipate, with a fire risk where it meets a source of ignition; the other covers replacement oil filters able to seal poorly and lose engine oil. Three owner complaints are logged with NHTSA, one each on tires, visibility and steering. Wheel and tire specifications, wiper and glass procedures and steering linkage and gear adjustments are all in the manual, alongside the transmission and lubrication service the recalls point to.
