What is the reason your 1995 sportage automatic delays shifting into high?
it delays bcause the computer has to see 1/4 engine temp. on guage, this protects the engine from "bogg load" when engine is cold. Just let engine warm up to 1/4 on engine temp guage on colder days before going anywhere. This is true for all sportages from 1995 thru 2001. Hope this helps.
