Transmission Linkage Rebuild

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.
