Side shift tranny rebuilt
All gears shift beautiful but 1st, linkage adjusted properly, bushings all new No issues with clutch tube in tunnel New PP, TO bearing, 6 spring clutch disk Stock flywheel cut .025" and TO bearing fork pivot ball washer added by .025" to the stock .060" All motor mounts good Clutch adjusted properly Used very good 1st reverse slider Used almost new 2nd-5th dog teeth with appropriate brake bands etc. Used NEW synchro ring About half the time it goes right into 1st very smoothly. No grinding, no issues with reverse, linkage feels great. Other times will not budge into 1st gear. By going into 3rd gear first then trying seems to work most of the time as workaround. SO after reading numerous threads we have concluded that could the issue be 1. Are new synchros much stiffer than used one. SO DO THEY NEED TO BE WORN IN? Could that be part of the problem and could problem diminish with use? 2. And Using a 2-5 dog tooth gear and brake bands also be part of the problem? I do have original 1st gear brake band and am willing to buy the correct 1st gear dog gear. Also I have many good usable "worn in" synchro rings to use instead of the new one. So if problem does not go away, could I be faced to replace the above to get it right? I have no issue doing so. Just want it right. So anyone else faced with simliar issue and how did you solve it. Some Prior threads seem to point into maybe not using a new synchro and not using the 2-5 dog gear. Thanks jjs3rd914 |

Thanks all,
Yes all bushing are lubricated. Everything done by the book on the rebuild. I'm using Kendall NS-MP 80w-90, which I use in our 74 911 as well. I've read that Swepco will find a leak very easily--True?? Anyhow. My best luck is going into 3rd then1st, seems to work better than going into 2nd. It also seems to help by going into first directly when just coming to a stop as others have pointed out. That works great at a stop sign, but at an long red light - nah do not want to leave clutch in while waiting. So we'll give it some time to break in and report back. But it seems to me there must be a solution without going exotic like cable shifters etc. I can tell you. I bought a new 914 in 1972 (yes we are that old and only paid around $4300) and that was of course a tail shifter. I do not remember having this type of issue we are having now with a side shift! Of course that was xxx years ago so memory might be a little foggy. Thanks jjs3rd914 |
