6-Speed Manual Transmission Swap

[ms38w]

Lord Aries,  how's the shifter throw?  Long or short?  The only thing that has kept me from buying trucks with manual trannies is the long shifter throw.  I like 'em short and tight...like Danica Patrick...I mean like her car's shifter

much better that way


LA, what kind of job do you have that allows you to afford these crazy mods and their possible malfunctions?

mee too !!!

[Lord Aries]

Kavesman, we'll talk sometime when/if my current motor blows up...

ms38w, the throw is not bad at all and you get used to it real quick. You can drive it like a sports car with pratice.

joeami, its not how much money I make (which is NOT a lot at all ), its the fact I do pretty much ALL my own work... I also am very good at finding low prices on stuff I need (thats the little bit of Jew in me)... For example, usualy I prepare months in advance for an expensive mod, buying parts along the way until I have all i need to get it done...

OH and most importantly in order to afford my modding habbit I do NOT have any pets, wifes and/or kids. LoL

Cool.  That is the one feature (ZF-6) that I wish for nearly daily (except when I was having left knee problems).  I almost ordered an 8.1/ZF6 2500 HD but couldn't justify loosing all the features the AV has. 

You have my mind clicking...   Its almost a reversible swap.  (Just have toput my full console back in).

In that writeup he mentioned "nitrous".   It didn't have nitrous the last time that I raced it.

Looks great Aries. Can't wait to see it in person.

Nice swap i am relatively new to the board and catching up on the past. Would it be possible to obtain a list of the parts you need to do this swap from you? what was your approximate cost. Any help would be appreciated. Thanks for you time.

The problem you will run into is finding a ZF-6 Transmission for as cheap as I did. It took weeks to find one in running condition and it was literaly one of two in the whole country. No joke, I called every parts yard I caould find and ones that do national searches... You would be looking at $3,000 for a remanufactured one!

Another member here (Lukas) is doing a Manual conversion as we speak! He is doing the NV4500 5-Spd and I have been helping him with the parts he needs. Once he is done I am sure I can get him to post the exact parts he used.

I think you have forgotten about me.  I also have a FACTORY NEW zf-6 manual transmission.  It is one of the few things that was installed in a timely manner. I opted to cut the floor out of the truck instead of lifting the AV, and ended up going with an electronic t-case from a one-ton Silverado instead of the sloppy input shaft...too much play in it.  The only thing I lost was the auto-trac feature, but everything else is still done electronically.

[BLACKEDOUT_Z71]

MS38W you got any pictures of what it looks like on the interior? How much did you cut out?

Damn, so you are having to Re-Tunnel the body? That will be interesting to see... I still don't understand why you had an issue the input shaft on the T-Case, the input shafts are all the same design for the 241-243-246 t-cases... I have verified this with multipule places that rebuild the t-cases, either something was wrong with your t-case or the shop did not put it back together right.

The only real slack adder in my drive line is the super agressive Detroit Gear locker, that thing had a bit of play due to the spring locking assembely.

Third times a charm. Here is a pic with the stock input shaft next to the one they ordered, but didn't fit.

Yea thats not right... Mine looked the same as the one that came out only it was 29 spline on the input side...

Now this might sound like a dumb question. But changing from an automatic to a manual, would that cause any problems out here is california cause of the stupid smog laws? Or once nelson has erased error codes light wouldn't come on?

Don't see why it would affect the Smog ruling on the truck... for the Tuning you would ust need a Tune from a Silverado that had a manual and no more codes..

Thanks for all the help lord aries. I will wait to see if you guys come up with a post on the part needed for the swap. I am assuming your transmission came out of a 01-06 Chevrolet 2500 6.6L/8.1L 4WD

I am assuming this is somewhat of a list to start:

Transmission of Course
Clutch Master Cylinder
Clutch Slave Cylinder
Pressure Plate
Clutch
Associated Bearings
Flywheel
New Starter for Manual
Clutch Pedal Assembly
Lines
New Input Shaft for T-Case

By the way where did you order input shaft from?

Yep, the trick is you need to mix the following to make it work.

- Flywheel from a 2500HD with the 6.0L V8 and a 5-Spd Manual
- Clutch and pressure plate from a 2500HD with the 8.1L V8 and the 6-Spd Manual.
- Slave and Master from the 2500HD with the 8.1L V8 and the 6-Spd Manual

The 4wd ZF-6 has a 29 Spline out put shaft, you can eiether swap the shafts on the t-case (which didn't work for ms38w)... Or just get an NP243 T-Case from the 2500HD 8.1L with the 6-Spd Manual and just swap it into the truck. You will just loose the Autotrac 4wd features but, who cares about that anyways? Personaly if I had the money at the time and had known, I would have swapped in the fully manual NP241 t-case and done away with the electronis all together! I still plan on that if I can't sell the truck...
