Zoltan,

If the transmission is shifting with a bang, you may be approaching the
point where there will be a bang and your forward motion will cease.
Reverse will still work.  I had had taken my van to an A/T shop at the
sound of the first bang, I would have saved much grief and may be some
cash.  Based on my experience with my '84, your A/T needs serious help.
