Question for auto transmission gurus.

Might also be worth getting the MAFs checked out, they can cause gearbox funnies.

If the MAF could cause transmission issues they would be consistent regardless of transmission mode. MAF symptoms are rough idle, loss of power, engine 'roars' and often fuel/air mixture error codes.

While it's shuddering you need to look at the rev counter needle closely. If the torque converter lock-up clutch is causing the issue the engine revs will fluctuate in sympathy with the noise but it's only usually by 100-200rpm so you need to watch carefully.

usually... but I've seen a few gearbox funnies on A8's (similar gearboxes) that have been traced to MAF issues. The MAF is 'good enough' for the engine, but the tranny doesnt' like it.
