Nick, I had this exact same problem in a 64 Dodge many years ago. I thought that some check ball in the valve body was sticking due to varnish in the fluid. Once unstuck, it worked fine until the next day and then it was stuck again. A simple fluid change fixed it.

It does have a few small problems though, one being the power steering pump growl which I mentioned in a previous post. The other problem is that the Powerflite transmission when cold, doesn't want to upshift to high gear in D. After about 10 minutes it shifts fine all day. Somebody told me to add about 8 ounces of Berrymans B-12 Chemtool to "free up" parts that may have been gummed up from the years of sitting. The car has 70,000 original miles and has sat for the last 12 years. I'm not big on additives but am willing to give some a try as long as no harm comes to the transmission. I've heard these solvents can mess up seals by softening them up too much causing leaks later on. Any info greatly appreciated. thanks, Nick Nichols ************************************************************* To unsubscribe or set your subscription options, please go to http://lists.psu.edu/cgi-bin/wa?SUBED1=l-forwardlook&A=1 ************************************************************* To unsubscribe or set your subscription options, please go to http://lists.psu.edu/cgi-bin/wa?SUBED1=l-forwardlook&A=1
