I just replacd the automatic transmission in my 01 Civic. The new one had 27000 miles on it and came with a 60 day warranty. When I first got the trans installed in the car, the 3-4 shift would hesitate somewhat. The RPM's would jump slightly, then it would shift. I replaced the shift solenoids, because those were off of the old transmission.
Well now, it jerks into 3rd and then 4th doesn't engage at all. Is this definitly a bad transmission, or is there something else I should look at? Thanks
