Transmission problem
2006 Hyundai Getz 4 cyl Front Wheel Drive Automatic 72000 miles

Hi, the getz has started with a problem. When going through the gears, between 2nd and 3rd, it is as if it çlutches" to long, the revs go up and then the gear engages and the vechile lurches forward. Any ideas? What can I do to eliviate this problem? Another thing that happens very seldomly, is that it sometimes doesnt go back to 1st gear when stopping at an intersection. I f one turns off the engine and restarts it, it is fine, woulld appreciate advice with these problems. Thank you.

1st step should be checking tranny fluids
and then scanning for codes
have to use a scanner to get to tranny codes an OBDII reader will not get all the codes needed
as to what to suspect, its internal tranny issue
and codes should help in pin pointing the problem
