350 turbo shift issues.
350 turbo had some shifting issues as far as going around a turn it would not down shift.. Changed the fluid and filter.. Problems now.. I can put the truck in the drive position and it will move however it will not shift.. I have to crank it down to 1 and then manually shift it from there.. It will give me good shifts when I shift it at the correct rpm range.. I put too much fluid in at first.. I read that the trans holds about 8 to quarts. But what I did not realize that it was dry capacity.. My fluid capacity now from what I have read is four quarts.. I over filled by two quarts I put six in.. Experienced the problems got more knowledge and sucked the other two out.. I check the fluid now and it is at optimum level however it still shifts manual.
