I DID SEARCH. AND HARD.

Basically my friends new (for him) lnf is stuck in third we believe and won't go into neutral or any other gears .... Clutch always has to be in.

The shifter is completely loose.

Is this a linkage issue (roll pin or whatever) or is this a problem with syncros ....

??

sounds like the roll pin.

Miltb

I'm hoping so because that'll be way easier to fix than replacing the whole tranny.

Thing is .... The previous owner had it looked at by a transmission shop .... They replaced the cables .... But believed it was still an internal issue .... Perhaps they missed the role pin being wrecked?

Gonna ask a stupid question, the cables are connected to the bottom of the shifter?

I'm wondering if the shifter arm may have got water and frozen. Helping the roll pin go..

Miltb

Well I'm gonna check because I found mistakes made by genuine mechanics before .... Baffling!

I would imagine the new cable they installed were properly attached to the shifter.

Miltb

Well it's certainly likely that water freezing could have wrecked something ....

​​​​​​If it was the syncros, wouldn't some gears at least still work ?? .... It's basically the shifter is floppy .... Like just sprung to middle I believe.

But it's in third I believe .... But permanently.

That's assuming they did replace them. They are known to pop off or be difficult to pop on.

Miltb

Ya I guess you can't always trust others to do the job right until you've seen the work .... I'll check it next time I'm at his house .... I'm also gonna check the roll pin.

​​​​​I can't really find anything definite about how to really fix the roll pin .... And where to find a super short punch. It's a 1"-1.25" role pin with thickness of 3/16 but they seem to break even when replaced.
screw better? 10-24 ?

a bolt will shear off quite easy, and likely would cause some slop in the shifter. a split roll pin is the only way to have it solid.

what ive never figured out is why the ss/sc f35 never had the roll pin issue and the tc did.

I believe someone has a stronger/hardened roll pin for sale. Perhaps powell?

Miltb

I'm pretty sure they did too ....

That thread was started in 2007 .... Before the TC I believe .... I think it's a Cobalt f35 specific issue .... Wonder if the redlines has the problem too ....
The f23 does not have this issue.
Someone fixed theres pretty permanently by using a grade 8 10-24 x 1.5" bolt ....

Miltb

Yes Powell apparently has them.
Dunno how to buy anything from him though.

I'm gonna try and replace it with a basic replacement pin with two smaller pins inside as someone else did this and it seemed to help.

Cool thanks .... I will likely be getting rotated mounts from them too ....

So UPDATE!!

We tried to see if it was the roll pin .... doesn't seem like it ....

It won't move side to side .... Basically jammed in 4th I believe .... Then when you move it the only place it'll move to (nuetral ish area) it won't move side to side like nuetral should .... Totally jammed.

It's the lower roll thing on the transmission that's jammed .... Won't physically move .... upper one move fine ....

Whats the problem then??

Ideas??

Miltb

In the photo, it's the lower rusty thing that's seized and won't move .... The lower thing that the lower linkage cable Connects to.

So what's the issue?

C0balts5

That's the shifter arm that goes into the transmission, that should move by hand easily. If that shaft is not moving at all then odds are something broke inside the trans and is wedged against the shaft and or shift fork

Miltb

Thanks .... That's what I'm thinking ....

The lower shifter piece just doesn't move at all!

Guess Engine​Engine/tran swap happening for my bro .... free ....

C0balts5

That stinks, thankfully mine was replaced under warranty by the previous owner. Still had to pull my trans out 3 different times unfortunately
