transmission jerks

[Baldwin]

I've asked this before because I had a VERY similar problem early on that was backed up by a TSB...

do you have/use a remote starter?

TSB?

I also had an ongoing problem with my solenoids. You can read about it all here

Intermittent, hard to recreate, real pain in the *** annoying. Mine had a missed shift as well, which happened at a specific speed (ie, a shift point that it would miss). But I suspect that more than one of my solenoids was failing, as I had jerky downshifts too. Replaced them all and so far no issues.

That may or may not be the problem: check mounts as well.

But read through this, to see if any of it sounds familiar

Do you get a check engine light? My sisters VX is having a similar issue and is complaining about the speed sensor. Using a elm-327 and my trusty Android you can see the speed bouncing between 20-100 mph every second even when at a standstill. "Rebooting" the VX fixes it for a bit. The sensor is petty expensive (over $250 for a Napa special) and you have to disconnect the auto shifter from the tranny to get to it.
