Automatic Overdrive

[BonesTheRipper]

Hello Fellas,

i have a 93 camry LE... automatic. It has a bad habit of not engaging overdrive until you've been on the road for a while. only on cold starts like early in the morning on the way to work. i think the overdrive doesnt engage until about 4 miles into my commute. i noticed that when i warm it up before i leave, the overdrive kicks in sooner. this is the 2nd trans this camry has had... any thoughts, tips, tricks?

thanks,

bones

Mine does this too, I think its just because the trans is cold.

This is normal operation. The ECU is programmed not to engage OD until the engine/trans reach a specified temperature to reduce unneeded wear and tear on the transmission.

Can always do a check of the engine coolant temperature sensor and make sure it's still measuring the correct resistance for the temperature.
