reborn55,
But this tranny started the shudder a couple of months after being installed new/empty. You still think a drain/refill would help?

What's the EPC soleniod? Do you know why the EPC would cause the shudder?

drg84,
It is an Automatic Overdrive Transmission...interestingly if you hit the OverDrive OFF switch it makes no difference the shudder still happens. I will try the cable adjustment.

Thunderbucket,
That's a good idea too.. I'll look into it.
