Men denkt het volgende: Third is bad piston seals on units prior to 1985.

If your M46/OD starts dropping out of overdrive in hot weather, the likely problem is worn overdrive actuating piston seals which allow leakage of hydraulic pressure. The original blue teflon seals are not available from Volvo or anyone else because according to TSB 43-14, new pistons and seals replace the two piece teflon/o-ring seal and piston. The new seals will not fit the old pistons due to differences in the grooves. See John Sargent's excellent illustrated discussion of how to replace these seals and pistons. Replacing these pistons will likely restore your O/D's ability to shift when hot.
Sorry voor al het Engels. Komt erop neer dat de O-ringen rond de zuigers die de koppeling van de OD aandrukken gaan slijten en er niet genoeg druk overblijft om de OD ingeschakeld te houden.
Dit is de "illustrated discussion" om nieuwe zuigers en ringen te installeren, de bak kan op zijn plek blijven: http://www.brickboard.com/FAQ/700-900/Ov...eplacement
