I'm interested in buying a 99 civic automatic. Very clean looking car but the thing that had me concerned was the way the transmission shift. From 1 to 2 it shifts fine but It holds 2nd gear like it doesn't want to shift up to 3rd it doesnt' shift till around 3000-3500 rpm, It over revs in gear. I've never experienced a car with a slipping tranny but if you ask me this doesnt feel like a slip because its always in gear. The tachometer also did this thing where the needle would just wobble up and down. There is also a CEL for a p0420. Today I test drove another civic that was only a year up to compare shift quality and it was the same way, over reving in gear. when it shift up it was smooth no jerky feeling like you would feel if you put it in D with the motor reving around 3000 in nuetral. I've never driven an automatic civic so Is this a coincidence that both trannys are going out or is this normal on these hondas? One guy told me that it was fine and even suggested I take it to a shop before I buy so I can see for my self.
