I have a Rennshift on my car and it works just as advertised.

The key is to take your time when you adjust the linkage to get it just right.
That has nothing to do with the Rennshift though, it's the same for the stock shifter.

Brian, it'll be an easy fix. It just needs adjusting as the linkage has been disturbed during the engine refit.

Anyone game to come over and “easy fix” mine? Have fooled with it incrementaly and systematically for four hours and a fix to one area causes a new problem. I need an intervention before I send it sailing into the woods.

It took me 5 minutes to set mine. Make sure there isn’t anything rubbing or binding in the tunnel (or anywhere else) and all the clamps and set screws are tight. I set both the shifter and trans into 2nd gear and tightened the bolt. Mine was a little difficult to get into gear, I adjusted some slack out of the clutch cable and then it moved easily.

A rennshifter just duplicates the stock shifter but has no slop at the shifter. It really can’t make the shifting worse. Every thread I’ve read that mentions an issue with a rennshifter turns out to be something else. Loose cone screw, interference in the tunnel, ect.

This is a clutch problem... could be adjustment, warped disc, bad or missing pilot bearing.. something is keeping the mainshaft turning.. your shifter has nothing to do with this

(IMG:style_emoticons/default/agree.gif) my car had that issue once, clutch adjustment made it good as new.

Need to do the same thing now on the 911

Good advice. It probably IS something else since shifting has never been effortless. Will have to go through the whole system. Thanks

Try a couple turns on the clutch cable nut at the pulley. It made a huge difference on my car.

It was the clutch that needed adjusting. An easy fix for expert Kevin Clarke, within an hour. Its now as sweet and silent as anything. Incredible. Now the fun can start !!!
