On the gearbox that is to be fitted to 1. J.III for France will you please see that the clearance between the synchromesh cam and the slot in the outer member is in accordance with the latest practice .001 to .004. If you consider that the 3rd. speed loose pinion could have less side clearance, then we should like to try this also as according to MX.{John H Maddocks - Chief Proving Officer} this clearance is responsible for 'chunks' in the transmission about which customers are complaining.
