Hi. I recently installed a used 4R44E in my '99 Ranger, 3.0L. I put a little over 1000 miles on it since it was installed. When I first put it in D it won't engage for about 3 seconds then seems OK. While driving it seems to shift a bit rough especially when it goes into passing gear but the shift points seem about right. There does not seem to be any hesitation engaging in 1,2, or R.
I read about replacing the seperator plate and valve body gasket but couldn't find out what the symptoms are for this problem. On another post someone's mechanic told them they had electronic problems with the engine causing shift problems but didn't get any more specific. I read about the throttle position sensor causing shift problems but my TPS seems to be OK. Would a band adjustment help this problem? What else should I be looking for? When I had the old trans in there someone told me that turning the idle stop screw could cause shifting problems. If so, how would I fix this? I had turned it because it would not idle (turned out to be the IAC) and put it back "about" where it was.
