Hey guys- had an odd thing now happen twice over last month. I punch it in 2nd and when I go for 3rd gear it does not happen. The transmission is then stuck in 2nd. Driven home twice in 2nd now. I don’t know much about 4 speeds (it’s an m20). I get under the car and pull the middle rod (I think it’s 1/2 rod) back towards trunk and it frees up the shifter and I am back in business. Any thoughts on how I should troubleshoot? Thanks guys..
