Finally got a friends gtx ready for it's first time out. The weather was nice today so we took it out. Here is the problem I adjusted the throttle pressure linkage so it shifts into 3rd by 40. Everything seemed nice till I noticed the trans will not down shift out of drive when you come to a stop if you pull the shifter into 2nd or 1st it comes out. This is a stock rebuild. Anybody have any ideas what this could be. I tried moving the throttle pressure linkage around didn't seem to help.
