SYMPTOM/CONDITION
Customer concern of severely delayed 1-2 upshift after operating vehicle in reverse, particularly when transaxle is cold. The 1-2 upshift may not occur
until vehicle has traveled as much as 1/4 of a mile and/or shift speed may be 10-12 mph above normal shift speed range.
Subsequent shifts will be in the normal operating ranges.
NOTE:
It is a normal condition for the shifts to be slightly delayed during very cold ambient temperatures due to transmission fluid viscosity,
cold engine performance, etc. Do not attempt to repair this condition if the shifts are only slightly delayed.
Check throttle cable adjustment and engine performance prior to attempting any repairs.
