I was wondering whether all 914's inherently are unable to shift from 1st to second without quickly--a slight hesitation has been my experience.
The bushing had been replaced, the shifter is a J West rennshift,tranny was rebuilt by Dr Evil, and it shifts fine from 2 to 3, and 4 to 5. Three to four takes a little work, but a lot less than 1 to 2 Any experience or suggestions here ? (IMG:style_emoticons/default/smile.gif) |

Went out to try shifting a lower speed/rpms. A little better.When pushing the shifter to 2nd it feels more like their is some sort of friction on the rod or something.

Did you get a chance to look at the gear stack and how it works? When you shift into gear, the slider slides up over the synchro band. There are common places in both the slider and dog teeth on second gear that could be issues, it could also just be a synchro that is not worn in. I would agree on one point that was made, take a look at the shifter adjustment and see if that can be optimized to give you more leverage to put it into second. Sometimes adjusting the bar in the tunnel and sliding it forward, into the couple, can give you a hair more leverage. Mike has certainly seen his share of transmissions, but getting defensive is pointless. Please take that the right way, a few of us have seen the inside of these boxes before, and broken a few of them in our day..... Jim, It can be decent to shift, so keep hunting for the problem. There are many places it could be, and you need to wrap your head around how it all works together to see where the issue may be. Look at all the bushings again, and the coupler that sits outside the firewall. That couple may look good, but new bushings in that makes a ton of difference. These little variations, the shifter, the bushings, the bend in the rod, and the setup of the transmission and shifter forks can all add up together to be hard to shift. Look for where the tolerances can be improved without looking inside the box first....do them all again if required, then you can think about what to do next. You can also remove the shifter from the transmission and see how it feels to shift into Second by hand...it should not be hard to do with no rod on there.... That may isolate where you look next.
