Coupla times with my 123 and 126, I've had rattling shift linkage 'til I had new bushing installed.

Hi Gang -
Is this a clue? Don't know if this is related to the Turbo/transmission problem but there's a rattle at steady throttle that seems to come from the gear shift area. Maybe a bushing is broken? Or the Kickdown cable Peter mentioned is possibly broken?

Thx
Larry

Hey Larry,
   I don't know for sure but that name is what a waste gate does.

Thanks Kaleb -- I am reviewing the WSM sections on the Turbo - I need your help on determining the names of the parts. I always thought I knew what a waste gate was -- actually I know what it does and what they look like on some race engines but on this 602-962 engine i have turned to the manuals
many illustrations to find the Waste Gate.

Question - the illustrations talk of a *"Charge Pressure Control Valve"* /(09-0050 Function of Exhaust Gas Turbocharger)/ - would this be the Waste Gate? It's the only part with a description that comes close to being a
*"Waste Gate"*.

Thanks again for sharing your knowledge -

The flapper above the turbo has nothing to do with the turbo. You need to hook it up to the waste gate on the turbo if you are trying to manually
operate it to see if you get boost.

  Hi Gang -
Didn't start early doing my trouble shooting - wife worked o'time. But what I did - hooked a vacuum gauge to the vac hose going to the the flapper valve above the Turbo - pulled approx 6" at idle and then went to
10 or more when I revved it up.   Then I re-attached the hose to the
flapper valve and revved it again - it lifted the flap valve as I think it
should.

This tells me the turbo is working - no noises from anything. I'm
back to the AT not dropping down a gear when I punch it.

     BTW, my wife tells me she hears a rattle at light throttle.  Not
sure what to make of that....

     What does the brain trust think?  What should I work on next?

Thanks Guys,

Thanks Kaleb -
first thing I'll try is hooking up the Vac Pump to the Turbo and see
what happens.... I was hoping one of the CVs is damaged as that's fairly common - but a leak in the vac system is also possible - and that may still prove to be a problem. May as well cover the bases. I have some inline filters George Murphy sent me - they are supposed to indicate a blown out
CV...

As soon as I find a way to hook a line to the vac pump I'll give it
a try..   I assume I can hook up the turbo end to the Flapper Valve
Controller?

Thanks again,
LarryT
