Chevy Venture hard shifting started at random only on occasion and not every gear. Did and fluid filter change and added a qt. of Lucas transmission stabilizer. Shifted perfect for almost a week then hard shifts came back only this time in every gear starting after about 10-12 miles of driving. The simplest way to check if the (!) is to blame is after the hard shifts start turn the van off remove the key wait 1-2 minutes turn on start driving, if the hard shifts are gone more than likely the (!) is the problem and it will need to be replaced. I have ordered the part waiting for it to get here so I can replace it. If you are not able to DIY take it to a transmissions only shop not a big chain that works on transmissions too. Cost will be between $600-$800 if done by a shop. Do it yourself cost is $80-$100.
