was fine untill I had the trans flushed ( if you remember I had a radiator leak the tranny fluid into the water and visa versa) only when it sits for about 4 to 6 hours when I first start it and put it into gear it takes about 15 to 20 seconds to fully engage. after that its fine. am I missing somthing? I had jiffy lube flush it and they used reg tranny fluid and added the modifier. would that make a diffrence or could it be something else. tranny only has 15000 miles. never had this problem befor.
