i have a 1996 ram 1500 and the overdrive seamed to not kick in i was doing about 70km and my rpm are around 2250. can anyone help.

 

check engine lite on? Any codes? What's the temp outside?

 

there is no engine lite on and no codes the temp was -23c/-5f.

 

Might just be too cold for the PCM to go into overdrive... I hear rumors to the effect that it won't if it is too cold..... Is this something that just cropped up recently? (like, when the weather took a serious turns towards the arctic? )

 

You must be in Canada eh? I know a lot of dodges that won't shift into OD until they are up to temperature, can't remember if they designed them like that or if it's a byproduct of trying to push frozen ATF through the trans . I'm pretty sure though that the PCM won't let it shift til it warms up to a set temp

 

i had the truck running for about 30 min before leaving.

 

But the big question is...did you put it in neutral while it was running for 30 min, or leave it in park?

 

in park

 

Doesnt really circulate fluid in park. How long have you driven it?

 

it seat from 7 am to 2 pm and i drove it home which is adout 30km so about 40 min that is city and highway driving.
