i have a US version 1st gen paseo and i am having a problem with the tranny. When i have not driven the car for a while the car drives fine, but when i have been driving it for a while the tranny will not shift to overdrive. it is getting stuck at 3rd gear. i have an automatic. any help. thanks

Have you checked the fluid level ?

[cynos23]

yes i have and change it too.

Its probably coolant related, chk the coolant level, the car may have a bad water temp sensor in the radiator. the computer will not allow the car to go into o/d until its warm. If sensor is bad, the cpu will get a bad signal.

do u guys know where it is located? thanks for the inputs

Is there a tranny filter and have you changed it? clogging will cause the problem, is there hard shifting.
