My 1994 525 TDS auto has started to 'lose' drive when I break hard or, more and more often, just bring it to a standstill. Has anybody else experienced this problem? Could it just be caused by low fluid levels? From other documentation I've read this model was fitted with a sealed transmission so as far as I know there is no way of topping up the ATF unless someone on here can tell me different.

As always, any help greatly appreciated.
