Auto transmission to manual conversions

[jmscon]

I've been having problems with my transmission in my '02 dodge and wanted to know how hard it is to convert to a manual? Would the computer prevent me from converting?

Had an '09 with a stick six and loved it! Just didn't love the other things about that truck. But if I could put a stick six in my '02 I'd be pretty happy.

Anyone had this done or know someone who has? Good or bad decision?

Thanks!

look up on the good ol cumminsforum.com   they have guys that do that kinda stuff, just have to look around.   everything is there to do the swap just have to get all the nessesary parts, ( sure you already knew that)   the holes are there because all trucks are made the same.

Just make sure to stuff a 6 speed stick to it!

Did it to my '99. NV5600 baby. Works awesome! Not cheap tho

My brother in law did the auto/manual conversion on his 2nd gen 24V.

Started with a NV4500 and ended at an NV5600.

The swap seemed pretty straight forward.

No computer issues, unless you have cruse control.  The 47re isn't a computer controlled trans.
Tough part is finding a manual trans.  Ive found a few north of the border, but they aren't cheap, and usually need work.
Best bet is to find a donor truck, swap parts, then sell the donor as an automatic.

You will have to swap out the shaft in your transfer case if it's 4wd.  Different spline count.
shorten the rear drive shaft, and lengthen the front. (2" each if I recall)
New pedal assembly and hydraulic system for the clutch.
New or modified cross member.
Clutch and flywheel

it's too bad everyone stopped buying manuals before 3/4 and 1 ton trucks went to 5 and 6 speeds.  they're out there, but hard to find and usually expensive as hell, and that goes for all makes.  don't forget you'd need the pedal assemblies, master/slave cylinder, and a flywheel too.

the old heavy duty cast iron 4 speeds used by ford dodge and chevy are all over the place and can be had for $100 sometimes, but they were sure a lot more common in their era.  i've looked at converting my old ford to a 5 speed and would almost be money ahead by going with an aftermarket overdrive setup, since a ZF 5 speed can run over $800 just for a core that needs another $1500 to rebuild.

NV5600's aren't cheap, neither is rebuilding one. Unless you have some sentimental attachment to the truck you may be money (and time) ahead to just trade it off for a stick even if you loose a bit on the trade, just chalk that up to what you would loose on the swap.

My old 01 cummins auto started slipping at 75k, I had a full billet build done at PDR in Canada, Steve Troyan was the builder. 110k miles later, countless 4wd boosted launches at the track with 35 inch tires plus ALLOT of daily abuse and weekend towing with zero issues. I sold the truck 185k, talked to the owner a couple years ago he had a bit over 200k on it still with no issues.

Expensive!!  5600 isn't all that strong if your adding power.  Clutches cost a lot too!  A rebuilt auto (By a good builder) with the upgrades is very strong and durable.  Stronger than the manual.  4k$ would do it.  Swap the truck for a stick I would recommend.

WHAT DID THAT COST?

So I looked at a couple 4500, looks like the 5600 ratios are more for towing than a high top gear for milage. Found a refurbished 4500 for ~$1k (just the transmission) found a kit for ~$3700. Supposedly the only thing needed with the kit was pedals from a junk yard and modifying the drive shafts, cutting a hole for the shifter and changing the trim on the steering column.

The g56 is known to be a stronger trans.  Coupled with a good clutch.
Nothing wrong with a 4500, plenty of guys running them.

Where did you find the kit?

$7k, it would have been closer to $4k without the billet parts. Each billet shaft adds between $700-$1k. If you want to do 4wheel drive boosted launches you need the billet parts. If you just want to tow and drive it, no billet parts are really needed until you get an exhaust brake then they recommend a billet front hub/shaft if I recall correctly. I also had a triple disc billet converter, which was about $400 more than a quality single disc at the time. When I was racing the truck I would leave the line at around 15-20psi boost (any more would spin pretty hard on 35 AT's) and lock up the converter at about 20 feet out 40psi boost and leave it locked up through all the gears (very hard on the trans and drive train) until I hit the shutdown area. NEVER felt it slip and I did it countless times. The more I type the more I miss that truck 

If you've never ridden in one during that launch lock up in 4wd scenario..... Don't, you'll want to feel it time and time again.
