C4 NO THIRD GEAR

[Jrcmutang]

Got the car on the rollers and everything was going great.......until he clicked it in third and it free revved. Question is, the only thing that I had changed is the trans brake VB, could he have used the same gasket from the old VB and that would cause the no third gear, the old VB was a reverse manual with no brake is all?

You still have 2nd?

[Jrcmutang]

Yes still have second and reverse, second snaps in gear, trans feels great besides no third

[mustang8998]

Sounds like something in the VB, then. IIRC, second and third share the same band is the reason I asked....to rule out any problem there.

[Jrcmutang]

I am going to order a new gasket to night and try that, fingers crossed

[slow86fiveoh]

Do an air check to make sure everything is working with the valvebody out then when u change the gasket if it still doesn't work it is an issue with the valvebody itself

[Jrcmutang]

any pointers on that

3rd is the direct clutches inside the drum.2nd gear band comes off.
prob the valvebody if all worked before.

heres a link for air check easy peasy
you need to ck the directs and listen for the ka thud it makes like he says in the vid. if its ok its a v/body prob.

[Jrcmutang]

is there a gasket that goes in between where the valve body mounts against the trans?

[bbfstanger]

no

[Jrcmutang]

Got it working, called Trans King, ended up being the linkage was out of adjustment. They said it has such a small window for clearance. Took it for a drive, just seeing if it pulled in all three gears, good to go! On the rollers hopefully next week!

[bbfstanger]

glad you got it figured out ,tranzking has a pretty fast release,good stuff.

[Jrcmutang]

Haven't had it on the brake yet, or experienced a trans brake at all, so I am pretty excited

[mustang8998]

Glad you figured it out!
