I just bought a 92 Jeep Sahara 6cyl. Drove if for about two days, everything worked fine. Now it will not go into gear without major force! When it is in gear it with not change gears. When parked it will not go into any gear except reverse, and this takes major force. Am i looking at a clutch replacement, and if so are there any good ones i should consider? Thank you for your time and your help in advance. (Manuel Transmission, just in case)
