2010 Dodge Journey
I have a 2010 Dodge Journey SE and my rpm Ramp up to
4-5 whenever I attempt to go 40-45mph the check engine
light is on and I took it to autozone & my code read
P0670/P0870. I took it to the shop that did my oil changes
because I thought they weren't topping off my
transmission fluids. So they told me I needed a new fuse
box, which baffled me cus I'm thinking why can't you just
replace the one fuse instead of an entire box.. idk. So I
picked it up Monday night at 6p by Wednesday the same
thing was happing again so they run another diagnostic in
it tells me I need a new engine computer. Which I'm still
trying to see how this is going to fix something that has to
do with my transmission. So can you give me some
advice on why I now need a engine computer.
