I have a 1991 dodge dakota with a 318 thats two wheel drive and when i hit the overdrive button it lights up but doesn't do anything? what is wrong?

 

when you hit the over drive button.from my understanding and how it works in my truck.is it cancels out your over drive gear so if you have a 4 speed like me it will shift down from the over drive gear to 4rth gear.

to notice any change you will have to be going well around 100 kilometers an hour.then when you hit that button you will feel/hear the truck shift down.

hope this answers your question

 

i did that and it doesn't do anything at like 60-65mph its runnung about 3100rpm! not so good on gas lol

 

huh ya very wierd.mine runs like that when i hit the over drive button(light is on) and when its off(light is off) it runs around 1700rpm.

 

could be one of two things... first your overdrive assembly probably needs adjustmant/replacement.

2nd (and less likely at this time of year) but if the transmission isn't warm enough, it won't move into OD... usually this occurs in the winter when the tranny is super cold.

BTW remember that you have 4 forward gears in your 44RE, and when OD is off, it only uses the 3 of them.

Cheers.

 

what would that run and where would i get one? Should napa or orilley be able to get the assembly?? thanks ,jared

 

and from what you described, i feel it's safe to say your overdrive unit isnt working.. enjoy your 3 speed. tranny is gonna need work.

 

yeah take it to a tranny shop and have them take a look at it

 

Ok i will see what they will say. well i get like 14 mpg but it does 3.55 rear end gears.

 

14 from a 5.2 isn't actually that bad
