I have a 2004 dodge dakota and was wondering what would be involved in changing out my manual 5 spd 4x4 for a manual 6 spd 4x4 and will it lower my rpms in high gear

2005 and up Dodge Trucks now come with a 6 speed. You maye be able to find one in a junkyard. It will bolt up just fine. You could also change your gearing in your differential.

Dont do it!!!! The 6th gear will not lower rpms at all. 6th gear in a NV5600 is the exact same as 5th gear in a NV4500. Plus, the NV5600 is a monster of a tranny, easily capable of 1300+ ft lbs of torque. It also is a heavy, heavy tranny. You would have to change driveshafts, tranny mounts, everything. The only difference between the two trannys is that 3rd gear in the 5-speed is made in a ratio between the 3rd and 4th gears in the 6-speed. However, in all honesty, I dont believe that the dakotas even use the NV4500. Thats a much heavier tranny than would be needed behind a little v6 or v8. If you're really looking to just lower rpms, I would personally go with a gear vendors overdrive unit. They're expensive, but not nearly as expensive as trying to make a odd-ball tranny fit in a little truck. I'm not sure if you could get the Tremec T56 to fit in the truck, but that transmission is a dual-overdrive tranny, and it would lower your highway rpm drastically. However, the only vehicles I've seen that tranny or variations of that tranny in are the Dodge Viper, Mustang Cobra R, or Camaro Z28/SS. I've never seen it in a 4wd truck or anything of the sorts tho. After all the trouble and trying to make stuff work, I would personally just keep the money and put gas in the truck sitting the way it is. Just my .02

I could be completely wrong (wouldn't be the first time!), but I don't know of a direct bolt-in 6 speed transmission that will fit a Dakota (especially a 4X4). If there is, it will lower your high gear RPM's IF the 6th gear ratio is higher than the 5 speeds' 5th gear ratio. If you're considering using a 6 speed out of a full size Ram truck, no way it'll work. In fact, with all the custom work involved to adapt ANY 6 speed transmission would cost more than the truck is worth! (Not slamming your truck, I also have a Dakota) If there is such a transmission available though, PLEASE e-mail me, I'd be very interested in it.

I find it very unlikely that this would help your milage at all. Dakotas don't get very good milage, period. Even a V6, which you probably have, will not get very good milage. It's possible that the overdrive in a 6-speed would be a little higher than the one on the 5-speed, but it wouldn't be enough to matter. The lower RPMs that you might gain could actually lug the engine and possibly make your milage worse. Regardless, you'd certaily you'd have to put about a million miles on the thing to make up for the huge cost of switching it over.

Diesel Dodge trucks have a six speed available. I don't know that it would bolt right up to a gas engine though. There may be an adaptor you can buy from Advanced Adaptors. I know I've seen lots of Jeep builders use the NV4500 5 speed from the diesels because of there low gearing and brute strength and that you can buy the adaptor to bolt to a Jeep 4.0l engine. I think the 6 speed is an NV5600, and yes, the extra gear would lower RPM's slightly.

depends on the ratio.
Just becaseu you have one more gear, it does not mean that in
6th gear you have less rpm at same speed.
You need to look on the ratio, to know.
Before you change, make sure its worth the money and you will be happy with the result.
The differences between 5 and 6 gears are, that the 6 gears are closer together. Usually those are used in sport cars and motorcycles.

it would lower your rpms a little in 6th gear but i dont think they make a 6 speed tranny for a dodge truck yet go to www.summitauto.com if it is available they can tell you all you need to know about the swap out

Well, along with the cost of the new transmission, you're looking at the work involved of changing it as well.
I'd estimate about 4 to 5 grand.

do it it will be better on your rpm's and gas milage but you would have to buy the right chip for your computer
