See tons of positive comments but can’t tell if it’s being used on a 4 or a 6. Who is using a Rennshift on a 6 converted with a side shift 901? Does it work for you? Love my teener but shifting has always been its weakest link. Fixing that make the car even better.

Same transmission, it doesn’t matter if it’s a 4 or 6 or 8 or Mazda rotary or Subaru
The only issue with a six is the shift rod has to be straight or it will hit the motor.
I have used my rennshift on a 4 and a six with the same side shift 914 trans. I then converted to a 915 trans. JWest will sell you the parts to convert the 914 side shift rennshift to a 915 rennshift. Pretty simple conversion.

Can’t find any mention on the JWest site of 915 conversion parts or a kit. I do see the 914 side shift shifter. Do not see a straight shift rod being offered. Hmmm . Still not clear on what the McMark mod is.

The shift rod has a bend so you are saying it has to be straight and that and the conversion parts are Sold by JWest. Excellent. Will go check the JWest site. Hope that is all the conversion pieces. Still not clear on what the McMark mod is.

JWest sells two Rennshift models
914-4 side shift
914-4 tail shift and 915 gear box.
I originally had my 914-4 shift rod straightened when I did my six. Later I converted to a PMS shift rod for my six.
I don’t think JWest sells six conversion shift rods anymore, but PMS and CFR (Tangerine Racing) does.

I’ve got the whole Rennshift package from the shifter to the transmission + the McMark modification.


I think I know what the Rennshift (Jwest) package is, and also the Tangerine linkage kit, but I am not familiar with the McMark modification. Could someone describe this and maybe post a picture? Thanks.

I installed a Rennshift earlier this year. It was an improvement, but wasn’t as dramatic as I hoped. But I’ve felt others and they were superb. Perhaps I need some more adjustment?

Regarding the slot for a hand throttle? It wasn’t hard at all to cut one into the baseplate and install the hand throttle per usual. Mine works great. I also used the Wevo knob, but I elected for the one that slips on with a crush sleeve.

I'm not sure I want to sacrifice my hand throttle mechanism.....

I've seen people jury rig them. I'd have to be convinced this is a huge step forward.

914forme modded his rennshift for the hand throttle


Here is a link to the thread showing 914forme's Rennshift modification for a hand throttle. See post #213. Here is the photo:


That is similar to what I was thinking. Have to look closely at how the space for the throttle handle baseplate is accommodated under the shifter base plate.
Also, possibility of mounting the hand throttle assembly say 2' in front of the shifter base plate on the tunnel by drilling holes for bolts and cutting slot for handle and shortening the rod the same amount (?)


To easy to do and no other modifications needed. Also gave me a good reason to make some chips fly.

If you don't have access to a mill, it can be done with hand tools. Drill a hole out back big enough for the post to run up through, and then just cut two down the center. It is strong enough that flex should not become an issue with the minimal removal for the handle to move.

You also have to drill one hole for the nub oil the hand throttle mount to key into.

Installed the Rennshifter and what a fantastic difference. After lots of trial and error, error meaning losing reverse and first, it is 95% dialed in. It is so precise and takes the guesswork out of Gear changes. Very solid and reassuring.

The final 5% is getting the shift into 2nd so solid, that there is no way to just Knick reverse.

Relatedly, The main issue is the reverse lockout tends to hit the shift lever dead center and locks out first too unless I move the lever a bit back to get around it and it totally locks out reverse. The solution was to remove it unless someone knows a trick.

Don’t need the Patrick Motorsport stuff since I already have a bronze bushing in the firewall, a straight rear shift rod with a ball coupler. The steering coupler seems redundant so it is all going back. If this was a new conversion to a 6 it would have been helpful.
