Hi folks

Have spent a number of days trying to track down a Filtran filter for a 2003 TD6 GM transmission, but to no avail. Amongst others, I tried LR via jaguarlandroverclassic- No longer available. Duckworth not responding to email enquiry, so suspect the same.
Have correct fluids to effect transmission/transfer case/differentials refresh, so would like the accurate/similar filter to do this essential part of the job...
I note Advanced Factors offer a Febi Bilstein item through this site and would like to support them as sponsors, but only if it is the most suitable, quality option.
Any suggestions much appreciated

Best
Jim
