4 speed return to center spring?

Post by brn2rde » Thu Jun 27, 2019 10:01 pm

The 4 speed trans in my daughters car has a shifter that does not return to center, goes into gear fine, but in neutral it just flops to one side. Is there a spring in there that might be kaput, and if so, anyone got a primer for fixing it?

Nope, that is normal. Unlike the 5sp, there is no centering mechanism. Sloppy by comparison.

Left is 1&2, right is 3&4, way right is reverse.

All that repair will do is correct play from wear at the rear shifter yoke and rod. It may improve things, but only if you have significant wear. It won't correct the design of the linkage.
There is no "centering spring" in the 4 because "center" doesn't correspond to any gear. With a five speed, "center" is 3'rd and 4th. Its a totally different linkage setup.

I agree with JT as I just worked on this a few weeks ago with my 4-speed. I tightened the "play" as much as I could which does help but will not resolve the issue. However I will say when I changed my original shifter knob that was very heavy to a very light one I also saw significant difference (not sure if that helps or not)
