Why does my jeep feel like the transmission going out but the tranny is good?

Hello, how did you "check the transmission" and find that it's "hood"? Diagnostic trouble codes don't always show up for this vintage of a transmission. Especially for an internal mechanical issue. There's really not much to "try" except verification of the cause of the problem by a skilled technician with experience and resources, and then possible transmission tear down -- if that's what it is. Too hard to know, but can be determined by a skilled technician. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
