This problem just started in my 02 Elantra auto trannie and has happened
only twice over the past two days.
Started motor (hot weather AZ desert) and backed out of driveway.
pulled lever into "D". started up road and trans would not shift out of
1st gear. (was NOT in 2nd "failsafe") Did not taker it over 3000 RPM.
Braked and tried it a second time - same thing. Pulled lever back
through 3,2 and 1, then back to 2 at which point trans up shifted to 2nd
gear and was fine all day.
This morning started motor and went through same startup and backed out
same as yesterday - all went well. Cruised up the road a mile to get my
mail. Placed in 'N' on side of road while opening some mail. Started
back home in "D" and would not upshift to second. Braked and tried
again in "D" - same thing. Tried a third time and trans shifted OK.
36,000 miles on OD - 2002 Elantra GLS
Complete trannie flush at Hyundai dealer at 30,000 miles and refill with
SP III. Old fluid was in good shape. Mostly highway miles at 75mph.
I do have extended warranty and bought the car with 15K on the OD
The only recent noticeable problem of any kind is an occasional slight
misfire or roughness at first startup in morning. No codes have been
set and I assume I have a spark plug or wire that is borderline.
Any suggestions would be appreciated.
