Hurst shifter boot help
« on: May 15, 2018, 11:29:20 am »
Hi guys,

I’m having problems with the hurst shifter boot on my 69.

The car has a ‘70 hurst shifter. The car kept popping out of 4th(sometimes 2nd) when decelerating.

I unbolted the boot from the tunnel and the car shifts great and holds on all the gears. It looks like the boot is putting pressure on the lever when in 4th that eventually pushed the transmission out of gear.

Any suggestions?

Mine car with the same setup does the same thing. I just leave the boot unbolted from the trans tunnel.

I wonder if it would help if you backed off the 2/4 shifter stop bolt a little.  Couldn't hurt to try.

I was wondering if the shifter has settings. How does one go about getting instructions for setting it?

Isn't there a spring and ball right under the top cover (on the PS) that if missed causes trans to jump out of 4th???

Mine does (did) the same thing...the boot is old so I cut it to relieve the tension.

The FACTORY 1970 shifter won't have stop bolts, If it's an aftermarket Competition Plus it will have them, and if they are adjusted improperly (too far in) it can cause the trans to pop out of gear. There are other things that can cause this as well, stiff boot, worn input shaft syncro teeth, worn 3/4 syncro, worn front bearing, worn or mismatched detents and rails... A properly rebuilt top loader using the correct parts shouldn't pop out of gear ....

I’m sure it’s the boot. Without it the gears engage and stay engaged 100% of the time.

I was wondering if there’s a way to shorted the travel of the lever so that it won’t compress the boot so much

Fixed it (for now at least). All the trouble came from the bottom rubber ‘ring’ of the boot. Right above the built in plate. Cut the whole boot off from the plate and glued a leather boot to the plate. Works great for now. But I’ll look into a more permanent fix. Until then, my ‘69 SCJ is part ‘08 Mazda RX8 :)
