ED, Weltmeister already beat you to it!! their 'performance' coupler bushings are hard plastic and round with no play. $21 for the set... sure beats $200 for the Wevo or Stomski

The deal with the 915 vs the G-50….. the G-50 was not built by Porsche (like the 915) it was built by Getrag and has a more numb ‘like any other car’ feel some people prefer it. A lot of 915 trannys are simply not maintained properly and thus are hard shifting i.e. if the clutch cable is not properly adjusted or the clutch is worn it will not shift properly and most people do not keep up with the adjustments. The 915s also had a tendency to wear out synchros when not driven properly or run with the wrong fluids (should only use Swepco 201). There is nearly no difference between a good 915 and a G-50 but there is a huge difference between a bad 915 and a G-50. Over the years the G-50 has proven to be reliable but not faultless. The biggest difference really is the G-50 is hydraulic vs the cable of the 915. The hydraulically actuated throw out fork needle bearings also tended to wear out and seize up causing a very hard and noisy pedal that requires engine removal to fix.

Bottomline- the majority of G-50 cars will shift well where as 915 cars you’ll have to be picky and actually drive them to evaluate.

This has turned into a good thread. Interesting comments, Whalebird and Butzip.

Ivan, in my experience the Stomski and Wevo couplers transfer more noise to the cabin than the stock coupler. If your splined coupler shaft is in good shape, then you can replace with the plastic Weltmeister pieces.

If anyone has a 915 shift coupler and needs help, I have a hydraulic press that can press the pin out and replace the plastic pieces, just let me know.

Thanks....I kind of wish I had gone with the Weltmeister then... I put in a Wevo @ $200!

Click Link - THIS??

so back to "well maintained" 915 and "hard shifting"

we are talking fresh 201 oil, keep the clutch adjusted and ??? what else
hard shifting - mine feels "stiff" is there anything to help on this, is it worn, is it normal? (I know.... go drive a couple other ones) but just thoughts

Nobody can tell you whether your box is right online.

so I was bored and just made new bushings on the lathe out of Delrin - I left almost zero play (under 0.001) in the pin and a snug fit into the housing.. for the 1/2 circle outter "lip" I just dermeled off the part I didnt want.... thinking of using it and returning the wevo

will post pics this weekend

SORRY OP for going OT on your thread!!!

whalebird

I've used many of the welt bushings without issue.

So I guess my 86 coupe with the 915 transmission and the factory short shift is the Porsche to buy...any takers out there...for $20k

whalebird

Deadhead1960, what flavor oil are you running?

Ed Hughes

Not necessarily. Many do not want the short shift kit.

Very interesting to hear about this - so if I read it right, the weltmeister bushes have a substantial effect on the 915 shift quality for a very low price? My 915 box is (I think) in good nick and shifts very well, in what way would the bushes make it better?

Again, apologies to the OP for going OT but it's great what these threads can throw up!

Ed Hughes

Maybe your bushings were replaced, especially if it is a track car. You can't fix what isn't broken.

True, the gearbox was rebuilt a couple of years ago and feels very fresh. Damn, that means I can't spend more money on it...!

No need to apologize...these comments/experiences are certainly not off topic and are very valuable to me. As I wrestle with my own decision on which tranny, I know for sure that 3.2 is just the car I want. The 964 with the power steering and more modern gizmos is not what I am looking for. For a guy like me who drove cars equipped with some really mediocre trannies in India for 8 years, I feel that I am quite well equipped to deal with the nuances of a gearbox such as a 915. If it takes my 997.2's physical presence to let someone hand over the keys of their classic 911 for me to drive then I am all for it. But I think it will have quite the opposite effect like hmmm what is this guy here with a PDK equipped car doing in my backyard that has the classic and last of the "true 911". I also feel that my only chance of driving these cars would come when I actually fly out to each of these different places and then drive the seller's car. That would mean once I narrow done my choices (based on my liking that I do not want cars with whale tail, too many mods, cars with poorly kept interiors, resprayed paint on the exterior, more than three owners..)to about three of four cars, then fly out from Seattle to all over the country..add to that the cost of the PPI, title, tax, registration...great I can see my 997.2 listed on autotrader and 6speed before I get my 3.2
