I have a 03 Dodge Dakota 4.7 4x4 automatic that the transmission went out of. I have a 02 Dodge Durango 4.7 automatic transmission laying around. Will it fit my 03 dakota?

Depends it can be very difficult to get the right used transmission on Dodges. The best way to tell would be get a part # from the dealer for the vehicle it's going into, then find the part # on the used transmission and make sure it matches.

I would say yes it will fit. They used the same auto tranny from 99 to 04 I believe. And even then they only changed the programming and electronics from that point to make it a 5 speed. The tranny itself remained practically unchanged internally. In fact a 545rfe will even work if you do the TCM swap. (Gives the 4 speed an extra gear)

I'd sure like to find out if that is true. Somehow I doubt the electronics can magically produce an extra gear.

Wikipedia answered my question. The 4 speed and 5 speeds are NOT the same transmissions. The 545 has an extra overdrive gear. You can't simply change the controller and magically get a 5 speed from a 4 speed.

It appears that the answer is yes. However, you will have a 4 speed automatic where you had a 5 speed. You will need to swap the controller and there may be some wiring to work out as well, not certain if the wire harness is compatible between the two controllers.

I have the 5 speed in my '03, I had the 4 speed in my '00. I actually prefer the 4 speed, it was less anemic at highway speeds. Gas mileage suffers a bit with the 4 speed.

Btw Pendleton is a spammer who just copies everything I say ignore him. If a mod sees this I think he needs a ban. Follows me and copies everything I say.

Yep doing it all across the site, for me too. The only difference is he underlines the punctuation 😂
