Your check engine light is something engine, not trans related and a 1990 vintage would be a C6 and that would definitely benefit from at the minimum of a 6 pass cooler

Hmm, maybe it is oil related. My factory oil pressure gauge usually reads about 3/4 of the way up when Im driving. While climbing hills, Im usually watching it like a hawk, and its usually pretty steady. The motor does burn oil, especially when climbing hills. If the oil level drops, the gauge will fall and the check engine light comes on. However, when the check engine light comes on while climbing, the oil pressure gauge was reading steady at 3/4. could the light be coming on because its burning oil due to the increased load?
