A few weeks ago I installed a 200R4 in my 69 Skylark. Everything went well, took some drive until I got the TV cable correct. When completed it was shifting great; earlier today I went for a ride and couldn't tell if it was shifting or not however, when I slowed down and stopped I could feel the transmission down shifting. On the way back home it started shifting where I could feel each gear. Was the trans shifting and I just couldn't tell before?
