I drive a 2005 sports trac. 2 years ago I bought an entirely new transmission after mine just stopped working. This last week I noticed that sometimes while accelerating between 20 and 30 mph my car would “catch” and the rpm would spike and eventually it would work itself out. Yesterday the problem became permanent and will not go above 20 mph. However it will drive in 2nd and 1st is there any chance I could drive it on the highway without doing furthering damage?
