Seems like I got the domino effect going on here.......

Got the plenum gasket repair done and took the truck out for a bop around town, drove a total of about 5 miles. Truck runs great, FANTASTIC even.

On the way back however, the trans started acting like it was slipping. Shift points seem like they are still where they should be. When it grabs a gear, it feels/sounds like its dropped into neutral for a brief moment THEN it grabs the gear.

Until this, I've had ZERO problems with the trans.

Fluid is still full (haven't changed it yet... ), I don't see anything vacuum or electrical related unhooked. All the linkage is hooked up as it should be.

Suggestions on what to check?

Thanks...
