Finally invested in a Renn shifter, and hopefully will put to bed all those shifting woes once and for all!!

Not that my mechanic doesn't know what he is doing, but are there any off the wall issues that might be good to know before we start the project?? I have all new bushings otherwise.

Get rid of the fore-aft limit stops. Seriously. Take them out and throw them away. The limits should be set by the transmission, not the shifter.

Also, good luck getting the reverse lockout to work. I just took mine out altogether.

Is the reverse lock out to keep from going into reverse gear when going from 1st to 2nd gear? If so, I had 1st capped off, and actually start out in what would be 2nd gear, is my 1st.

I had to remove the reverse lockout so I could get the shifter over for first. Once I did that, it was pretty easy.

According to that, then I shouldn't have to remove it in my particular situation?

Where do I go about looking up the instructions for adjustment at?

That's the problem, I'm not enjoying the factory set up.

My Renn shift install worked out great. Reverse lock out performs perfectly. I did install all new bushings which was a big factor in tightening up any slop aft of the shifter. I ran into a problem at the trans console, the hole for the stock sized bushing there was way bigger than the bushing, and the shift rod was very loose on the new bushing. Solved that with a custom machined nylon bushing and a couple of nylon ties to keep the new bushing tight in the oval trans console hole. There are other ways to address this issue as someone makes a brass bushing for that area. I don't favor that route because if the nylon bushing wore the hole into an oval, imagine what a brass one will do. Maybe if it is good and tight, allowing no movement in the trans console it will work well. I did post some pics of my fix in a thread back in say 07/08. The size difference in the custom bushing compared to the stock sized one is eye opening.

I just have the shifter, not anything from the firewall back that I am changing. I'm guessing you got some linkage from them??

No, no linkage. I replaced all of the bushings aft of the shifter. Firewall, aluminum piece just aft of the firewall, and the trans console bushings.

I see.

I replaced all those about a year ago, and so I hope there are no issues when the mechanic is installing it.

You must have adjusted them wrong. Seriously. (IMG:style_emoticons/default/smile.gif) They are for preventing excessive force beyond full engagement in the transmission. If you are not forcing anything, they are never used because they are adjusted with clearance at full engagement. Too many people can't stop themselves from banging gears, it's just a little extra life for the bushings to not be punished so much.

Most issues with the shifter come from slop in the bushings or adjustment being off. The RennShift is easier to adjust than the stock shifter, but requires good bushings for full benefit.

Mechanics tend to do a bad install more then novices, because they won't read the instructions and specifics, but novices are careful, pay attention, and this is just not that difficult. Some mistakes I have seen:

The metal bushing in the bottom of your shifter needs to be moved over to the RennShift with the shift rod clevis.

Adjust so the shift stick does not move to either side when engaging 2nd gear - the gear slot in the trans should align with the shifter springs.

Back off the stops so they are not touching during full engagement, as above.

I'll skip over the first line for the mechanic, but pass along the extra tips part, just in case!!

I have Rennshft in both Papa and Huey and love them. No other mods to the linkage.... Any 914 owner that drives Huey is amazed at how precise and easy the shifting is, though for some reason Huey shifts better than Papa?? No idea why... But both are good.
