Hello
I have been following this thread closely and saving my pennies to buy one of these adjusters My 914 has a tailshift 901 tranny and I just read this will not work on a tailshift Is there a similar tool one can buy to help with the adjustment of the shifter? The P.O. replaced all the bushings but I'm dealing with a renegade with a custom linkage Tranny shifts fine but finding the gears is still a problem. Im told trying to adjust without experience may lead to making matters worse Any help on this? Thanks Mike |

The tail shifter has a lot of slop in all of its internal shifter components, at the very least. Consider this, the stock 911 that uses the 901 has one internal slop point. The 914 adds two more points directly in line with that first one. So, while some work can be done to fairly easily remove the fore/aft slop (I have a solution in the works for this), the side to side is still pretty shitty. With a tail shifter I do what I call "quadrant shifting"; first is somewhere in this quadrant, 2nd in this one, etc.
A side shifter is a fairly cheap investment and can lend itself to some major improvements over the tail shifter. I have a nice improvement that is simple and makes the side shifter more gated than stock, so improvements for that system are available over the inherent improvement over the tail shift. |

Soooooo, what's needed to go from tail to side shifter. Transmission, complete linkage and engine crossbar. And a new firewall bushing. Ouch. Plus labor, so not simple, and definitely not cheap. And you're discarding the tailshift transmission, since no one wants them. Almost no one. A side shifter is a fairly cheap investment and can lend itself to some major improvements over the tail shifter. A cable shift for tailshifters would definitely be the way to go, should make a tailshifter work as well as or better than a sideshift transmission. Would probably be a cheaper and more effective solution for improving sideshift transmissions too, but unfortunately no one's come up with a really good one yet. Sorry Brandwood, nice try, no cigar. |

A cable shifter for a tail shift is folley. You still have the very large slop points in the transmission itself.The shift linkage external to the tail shifter is not all that bad, and is actually superior in some parts if all in tolerance. Side shifter conversion is cheap because the external parts to convert can usually be had for about $100-125. The transmission itself is not all that expensive, depending on your location. Sunny = cheaper. Salt belt = more $$. Some will never be happy until they have a gated shifter feel. I base my comment on the 100+ satisfied people that I have personally helped, that have been very happy with the change, and that feel it is absolutely worth it. As for cheap improvement, my side shift internal modification is working very well, has been tried by one independent evaluator and they were surprised and happy, and will not cost all that much when I have completed beta testing. Now that I am done with the move to my new shop, I only need to get set up to complete the R/D. I am shooting for $100. |
