I can't shift into second gear until I have gone a few miles.. the jeep refuses... Lol its a 93 yj 4.0 5spd. There is no noise or other symptom that I am aware of... And after a mile or two it shifts in smooth and quiet. And suddenly I have a flawless transmission.. I've checked the fluid.. up to level.... What's the deal? Is this common? Should I start looking for a new tranny? Or is there something simple I can do?
