Title: New shift solenoids no gears no park ?
Post by: BigBlockV6GMC on May 16, 2010, 11:49:17 PM
1995 GMC K2500 6.5-T 4L80E:

Ok I dropped the pan changed filter and shift solenoids refilled with fresh fluid and now I have no gears nothing forward nothing backward and there is no park.

When I shift back to park it clicks & grinds so shut it off, so with the shift lever in park I push the truck by hand it rolls freely.

So keeping my hand by the key I fire it back up no clicking shift through all the gears and still nothing go back into park position it clicks and grinds so quick shut it off.

Any ideas ? Went from R and 2 To no gears no park ?

I never had a 4L80E apart but if it looks anything like a 700R4 or 4L60E are you sure you assembled the internal shift lever back in correctly? It's the lever with the steps on it that sets the parking pin and also controls the valve body slider valves?

Sounds like a basic mechanical problem..did you remove the valve control body, if I remember correctly in the 700R4 the valve control body had to be removed to replace the torque converter lockup solenoid?

Did you remember to re-attach the shift lever linkage?

As much as expressed my Dislike of the 6.5er i honestly missed driving it, Its feels nice being back in the saddle of the Rig known as the "Turbine" . . .

Not really sure it how it got the Name Turbine, but that is what I and all my friends call it  :o . . .
