I've got a problem with my 89 yj with the 4.2 and BA10 5 speed peugot transmission. Just drove over to my mom's place to plow her out and Jeep ran fine on the ride over (about 3 miles). When I got to her place, I shifted into first, dropped the blade and made a short pass. At the end, I tried to shift into reverse, but the transmission was stuck in first. Shut the jeep off, restarted it, but still had only first gear. Clutch engages, but I can't shift her. Temperature is about 15 degrees. I'll listen to all your ideas--I'm stuck. Drove home in first gear, glad it was only a few miles.
Thanks in advance for your thoughts.
