Hi. First thread here but having an issue with my wife's td4 auto box. It's starting to make a rattling noise on drive. Bit like when you used to put cards on the spokes of your bike. (Showing my age a bit.) Exhaust looks fine as I have replaced the rear box and there is clearance. The drive shaft looks clean and there is no oil drips from any of the transmission components. The engine runs fine on idle. No issues as I have replaced the crank shaft filter with the modication from BMW and its not blowing oil out of the dip stick or any metal flakes in the oil. Thinking its possibly either a transmission or engine mount problem as the engine is fine on idle but starts to vibrate when drive is selected. Any help from the wise would be most welcome.
