Transmission Linkage Rebuild

March 25th, 2010 No comments

One of the things about my old transmission was the sloppy shifting. Anyone who drove it could tell you,  you never really knew for sure if you’d shifted into a particular gear. Well, I bought a new Hurst Competition Plus shifter, part number 391 3180, and took it over to Ray’s. We took apart the old linkage and cut the rods to the proper lengths. Then, we threaded the ends and installed heim joints. Where new bushings were needed, Ray machined some new ones out of stainless steel on his lathe. Then, he took apart the Hurst and made shims for every gear. This process basically took out all of the slop and left me with a REALLY nice shifter.

This is the old shifter - an old Hurst style one, but not the right one for this transmission.

You can see how the attachment is made between the rods and the transmission arms - the rod makes a 90 degree turn into that hole. There are plastic bushings (teflon?) that smooth the joint out, and the rods are then secured with a spring clip.

We replaced the old sloppy joints with really nice solid heim joints that took out all the slop

The heim joints are fastened with AN 365 lock nuts. They're not going anywhere.

Ray shimmed the shifter perfectly, so that there is no play in it. Very nice feel to the shifting now.

Transmission tunnel repair

February 19th, 2010 No comments

So, a previous owner installed some kind of wacky shifter. In order to make room for it, they cut a big chunk out of the frame that goes across the transmission tunnel. Since I’m trying to strengthen everything now, I am going to change the shifter out, and Ray and I will build some custom shift linkage (more pics of that later) that will fit better. We’ll bend our own rods, and use rod ends instead of the stock shift linkage mounts.

Because we’ll be making the new linkage and replacing the shifter, I repaired the hole in the frame. That will certainly make things stiffer, since it’s one of the few crossmembers that exist in this old unibody car.
