Come to think about it the od to d has always felt a little strange to me. Like if I give it a little gas it seems like it doesn't know to shift down or stay in od. I changed out my old tranny that let go but that still feels the same with this one. I wonder if my tcu has an issue? Car started life as a na that has gone the tt route. I've always thought about getting a tt tcu. Maybe I'll do that just to cross it off my list. I don't have any other auto z's to compare it to though so it could be normal.
