Can u make a twelve valve a six speed truck

 

Yup. Need the nv5600 engine adapter plate. Also, if it's a newer 5600, the input shaft is bigger, requiring the 6 speed clutch or an updated clutch from southbend or the like. I like the 6 speed gear splitting for heavy towing, but for occasional towing and daily use, the 5 speed does a fine job, IMO. Plus, since the 5600 has been discontinued, they're hard to find and very pricy. Getting more difficult to find parts for them as well.

Thanks alot. I have been wondering about this. My dodge is an automatic for now, but I am looking to change it later. Thanks again

 

Ur loooking about $1000 more for a 5600 than a 4500 just for the trans.

 

As much as I like to row my gears, if I already had an automatic truck, I'd drop the coin on a built auto. Puts all the power to the ground just like a stick (with a good clutch) and you don't have to change anything. Figure aboput 3000-3500 for a good build and it's just out with the old, in with the new

 

hey i have to ask u was ur 89 w350 srw, white and single stack?

 

It was originally a w250, single stack and white. When my buddy wrecked his d350, I swapped the rear and bed onto my rig. Ran a tailpipe for a while and dual 6'' stacks, but don't think I ever ran the single with the dual wheels. You from this neck of the woods?

Thread hijack over

 

Im from the east end of Long Island. If i could figure out how to post a pic id show u my truck i had to do a double take when i saw ur truck

 

Auto/5spd/6spd all used the same engine adapter.

 

Can you do a G5600 swap on a 2nd gen? Just wondering...

 

I sure hope so, I have one already, just need time to actually install it.

Do a search, there are several guys who have done it. Something needs to be changed with the clutch, I still have to talk to Peter at SB about.

 

Now - that's a modification I would give serious thought to. I really like how the G56 shifts, it's a lot tighter and more of a German car feel than the NV 4500 & 5600's. Let me know how this comes out.

 

I swapped in an NV5600 6 speed to get a better towing split than offered by the factory 5 speed. I've been running my '98 12V this way for several years, and have been very pleased. Although it seemed rather painful at the time, looking back, I'd have to say that the whole swap really wasn't that bad - the only thing I had to get outside help was shortening/balancing the driveshafts. If you choose to go the the same route, best of luck, I'm sure you'll be pleased with the results!

 

I have a gearvendor unit behind my 5spd and I love it!!!
