At a stop light in neutral, depress the clutch and snick it into 1st. Light changes, I hit the accelerator, release the clutch and bang it pops out of gear. That is number 1. A couple weeks later I am in the same position, but this time I have the shifter in my hand with the clutch depressed and pressed into 1st. This time when the light changes I am grinding 1st because it never engaged. That is number 2. Last Saturday after a quick wash in my driveway the same thing happened again. That is number 3. Now every time I stop I have put it in 1st 2 or 3 times before I really believe it is engaged. This is my 7th Mustang, all with manual transmissions, and this has never happened before. Not even once. In the 3 years I drove my 2013 GT500 I missed a shift twice, and both of those were going to 2nd under pretty heavy acceleration. I may be getting old, but I still shouldn't have any issues getting into 1st at a dead stop. Am I the only one?
