Got a zf5 s42, I was driving the other week and I never had a second gear till this day it shifted in and when I shifted out the shifter and handle read second but tranny was stuck in second. Took top half off trsnny and put it in neutral. What's the deal? And a second issue I'm having is I have to hold the shifter in third or it will pop out and grind. What could be causing that? Thanks.
