Valve body

[kober]

My dealer replaced the Vlave Body Cover in my transmission because he said it was the cause of my Check Engine Light coming on. Ever since he raplaced it, I now have a high frequency vibration at all speeds, even at idle. This is in addition to the 70mph vibration problem they still haven't solved.

Can someone tell me why a valve body cover would cause a check engine light to come on and why would its replacement turn my truck into a $40,000 vibrator?

Any help would be appreciated.

my guess would be the electronic governor, the cause of the light. as for why its a vibrator now , don't know about that.
