auto box - slight shuddering when accelerating in 3rd...

I keep testing to try to feel what's going on but can't put my finger on it...

 

In 3rd gear on quite low revs (2000rpm or slightly under) if I apply the accelerator fairly gently there's a slight shuddering sensation. I don't press hard enough to cause the gears to kickdown but it feels like it's having a slightly hard time applying the power for a second.

 

Very hard to describe but it just feels ever so slightly unnerving.

 

Any ideas? I'm going to try pulling the EFi fuses to see if that helps at all.

 

Oh yeah it's a stock Supra Twin Turbo by the way.

If none of these seek advice from reputable auto box specialist with knowledge of Aisin-Warner transmission and pray a lot.

Check gearbox to propshaft flange bolts, auto box rear mount, prop centre mount, prop to diff flange coupling and bolts. If none of these seek advice from reputable auto box specialist with knowledge of Aisin-Warner transmission and pray a lot.
