Re: 4.3 Valve Body

You're dealing with one of the problems listed below:

A cracked or leaking TCC solenoid.

A cut, damaged or missing turbine shaft O-ring seal.

A converter clutch valve which does not have full travel of 1/2" or is stuck in the off position.

A slipping clutch or band.

i found this by searching...as for parts...shit..try ebay, or a local tranny shop...anything rather than going to the dealer...that's if you feel like and know how to fix it yourself...otherwise you might as well go buy a new tranny or fork out the money to have yours fixed...

Re: 4.3 Valve Body

There is a guy on Ebay selling rebuilt valvebodies with a lifetime warrenty for around $125

By the way the Rock wants $315 plus a $50 core, I was recently pricing them, for one of my buddies, he ended up going with the Ebay guy, but it didn't get here yet.
