1985 300D

2 days ago all of a sudden w/o warning 1st gear started slipping, all other gears inc. reverse work fine. checked level and it was low.
next day decided to do a trans service rather than just add fluid. drained TC, new filter, and 7+qts dex lll

1st still slips badly but slightly different, not the shudder and bang just a smooth slip now from start and 2nd gear shift shudders for a short second 3rd is same and 4th doesn't bang

removed trans vacuum line but no change.

this car shifted like this b4 all this happened

1-2 very firm & fast
2-3 slips a little and slow
3-4 extremely fast almost a bang

also this car has under 60K miles

i'm prayin its something i can fix. you all havent let me down yet!
thanks in advance
