4 speed shifter slop(pic)

[chevyguybc]

heres a pic of the shifter retainer, you can push and remove it.. but the hole around the shifter rod seems a bit ovalized for my liking.. resulting in alot of slop...... you guys know if that gap is normal or should it be tight to the shift rod

so do i buy a new one fro lmc or whatever

That is not why you have the slop, the slop comes from inside.

yeah look at the area on the other side of that hemisphere. there are a couple tack welds in there that are prone to breaking and causing a lot of slop.

 

[chevyguybc]

tack welds where,on the retainer?

 

[dyeager535]

Just pull the shifter out and look at the end of the shifter. There are rubberish rings that fall apart, and the tack welds as previously mentioned. Also a few posts about these problems w/pics.

I believe there is a write up on Pirate in the tech section.

sure as shat i poped mine out as i am doing major body swap work. and i read this along with the posted link info. and i to have more work ahead of me. mine was broken at the welds. oh well i like playing with the welder.

i re-welded mine and used new o-rings from the hardware store and its all tight again

 

[chevyguybc]

well turned out my roll pins were half worn through. but the welds are great and the area where the roll pins seat are fine, im happy with how much slop it has now, if you shake the shifter a little, you can feel it go into reverse

im happy! now onto the clutch/flywheel motor, 63s, and rear driveshaft and shes back on the road,lol

whats the o-rings for?

 

[chevyguybc]

was wondering myself

 

[dyeager535]

They aren't actually o-rings from GM, the pieces I removed from mine appeared to be square cut.

I haven't looked at a shifter I can't recall what GM used them for, probably somewhat vibration control and somewhat for tightening it up a bit.

 

[chevyguybc]

pictures please of this square ring, not an o ring then is it..

 

[dyeager535]

All I got out of mine were some reddish chunks of hardened rubber. Most of the "ring" was gone when I pulled it.

I've got a newer trans in the garage, maybe it's still got something I can look at closely.

Apparently the right size O-rings will help, but I suspect the GM pieces were a fair bit harder than the average o-ring.
