If you dont understand how a Manual Transmission works and all the parts that go along with it, then you probably shouldnt attempt this yourself until you have learned.
Plenty of guys out there have converted there 2wd Silverados to run a Tremec T- 5. Speed transmission from a Camaro and this works great IF you are 2wd and plan to never towing anything bigger then a Jet Ski But, I wanted to keep my 4x. Towing ability if not augment those two things further so, that meant I needed a manual transmission from a Truck There are a few options for the GM Trucks in way of Manual Transmissions, here is a list of what was offered on the Silverados from 2.

Manual Comparison Note: For Manuals the Low gear is actually 1st gear but, since Low is only used for Towing and/or off- Road use the gear numbers are changed below for an easier comparison of the gear ratios. Type Model Low 1st 2nd 3rd 4th 5th. Auto 4. L6. 0e None 3. None. Auto 4. L8. None 2. 4. 8: 1 1. None. Man NV4. 5 5. None. Man ZF S6 5.
Let the Madness begin!!!! Step 1: Determine which Transmissions will fit the 5. L. ALL the motors in GMs line up for the full size trucks have the same exact LS Series Bell Housing bolt pattern, even the Duramax!!! So, you can bolt up any of the Manuals to the 5. L motor with out a problem. LS Series Bell Housing mounting points seen here marked in RED.*LS Series Bell Housing mounting points seen here marked in RED.
Step 2: Determine which Transmission best Suites my Avalanche and the Cost. I made some phone calls to a bunch of shops around the US that remanufacture these transmissions to find out which one would hold up in my truck and get the best cost. The NV3. 50. 0 was out of the question, its not meant for the kind of power my truck makes or the GVWR of the Avalanche. The NV4. 50. 0 was the logical choice since it is rated for 4. GVWR. It is tough and since it was used on the 6. L V8 it would be an easy bolt up swap just like the 4. L8. 0e Automatic is from the 2.
Trucks But, this is me we are talking about!!!! I dont want the logical easy choice; I want the complicated difficult choice!!! I want the ZF S6- 6.
Speed Monster Transmission!!! The ZF S6- 6. 50 is rated for 6. GVWR! Its big, its heavy, its made to take a ton of abuse and its just plain badazz! There are guys using stock ZF6s for Sled Pulling in their Duramax Silverados making over 8.
I think it can handle my ballsy little Turbo Charged 5. L To give you an idea of the sheer mass of the ZF6, the 4. L8. 0e and NV4. 50. The ZF6 weights in at a staggering 2. The overall case size is larger too and the gear sets are massive *Seen here are the ZF S6- 6.
L8. 0e on right.*Seen here is the ZF6 next to a cordless drill for size comparrison. Cost: A remanufactured NV4.
Shipped, a remanufactured ZF6 goes for around $3,2. Shipped!!! So, it looked like I would be doing the NV4. But, I got very lucky at the last minute and found a used ZF6 in working condition for only $1,6.
Shipped!!! The ZF6s are very hard to come by used because they just dont break. The only real way is to find one is out of a wrecked truck and buy it before a Transmission shop does. So, I went for it and snatched that bad boy up and it even came with a 9. For most all of the parts on this project you will need GM Factory Parts. I had a ton of help from a great guy named Pat at my local GM Dealer Parts Store, he even gave me wholesale pricing on all my parts since I work for AAA!!!
That said the entire swap can be done for just about $3,8. And in case you were wondering, I sold my old Stage- 3 Built 4. L8. 0e Automatic set up for $2,8. So, I only spent about $6. Drive Shafts. And I made up for some of that cost with sales of other old take off stock parts from my AV Step 3: Installing the Drive Line Body Lift: Unless you want to cut out the center tunnel/floor of your truck you MUST HAVE a 3 inch body lift to fit the ZF6!
According to the Chevy Dealer, the 2. Body Lift on them to accommodate the NV4. ZF6 and Allison 6- speed Automatic (as well as to clear the 6. L Duramax in the engine bay) Trust me when I say this is a must have because the ZF6 BARELY fit under the body of my truck Not sure if you would really need the Body Lift with the NV4. ZF6 . Flywheel and Clutch: The ZF6 will bolt up to the 5. L motor thanks to the LS Series Bell Housing design but, you need a Flywheel and Clutch for it.
The 8. 1. L and Duramax have a different Crank output on the Motor so cant just use a full set from one of them. And the Splines on the ZF6 Shaft are larger then the NV4. L set up either Enter Ace Clutch located in Sanford, FL, these guys know their stuff and got me set up. Simple solution, use the Flywheel for the NV4. L. Mate that to the Clutch and Pressure Plate for the ZF6 from the 8.
L/6. 6. L and youve got Fun times ahead. Yes, these parts all bolted together like they were meant to be Oh and unlike the T- 5. Camaro setup that uses a girly 1. And to top all this off, I also opted for an Upgraded Heavy Duty 8. L Towing Clutch/Pressure Plate combo for even more clamping force.*The Clutch assembly installed onto the 5. LTransfer Case: The Auto. Trac (NP2. 46) transfer case we have in the Avalanche does not have the correct input shaft size to mate up to the ZF6 (just like with the 4.
L8. 0e Swap). BUT! The bolt pattern is the same for all of the transfer cases so; this left me with two options: 1) Change to the Transfer Case to the 2. NP2. 63 or NP2. 61 (about $9.
Change the input Shaft $2. I went with Option #2 and changed the input shaft to the matching 2. Spline shaft for the ZF6. I did this myself in the driveway with instructions I got online, it was strait forward and fun to take apart the Transfer Case and get to see what goes on inside it. After doing this the transfer case bolted right up to the ZF6!
Now you might be thinking that the t- case from a 2. NP2. 61 or NP2. 63) would be a better option but, that wouldnt be entirely true. The power handling of the NP2.
NP2. 63 over the NP2. I love the Auto. Trac feature for driving in the Rain and driving in the rain is much trickier with a manual that has this much power in front of it. So, I chose to keep it and IF I ever manage to break the NP2. I will switch to the NP2. Seen here is the Input Gear Shaft, the old 2. Spline shaft is removed from the planetary gear set and replaced with the new 2. Spline shaft. Mounts: The ZF6 is almost 2 inches longer then the 4. L8. 0e and 4 inches longer then the 4.
L6. 0e so; I had to modify the Transmission Cross Member to work with the ZF6. This was easy and I finally got to use my welding skills! I also had to notch out a section of the Torsion Bar cross member as well to clear the Transfer Case.*Seen here is the 4 Inch Extension support mount I made for the Transmission from 1/8 thick steel plate welded at all the seam points. Drive Shafts: Obviously you will need to make some changes here; you can shorten your factory rear and have a new front made, this is about $3. I went for a custom upgraded front and rear using all Spicer Joints and Yokes for more power handling making my cost about $6. Starter: I had to swap out to the starter from a 2.
HD 6. 0. L to get proper engagement with the flywheel. Step 4: Installing the Other Parts Clutch Pedal/Master Cylinder: I ordered the factory Clutch Pedal for a 3. Silverado and after drilling out the pre- marked holes I mounted that it place. YES! Even though the Avalanche was NEVER offered with a manual transmission there are mounting points pre- marked for the clutch pedal! You will have to move the Throttle Body control (two small bolts and have to trim the Brake pedal down to a manageable size but, hey thats easy when the other stuff is all ready done for you!
Since the Master Cylinder was brand new it even came pre- bled and ready for install! There is a Clutch Safety switch that you can hook up that does two things: 1) Truck wont start with the Clutch engaged.
Releases the Cruise Control if you push the Clutch in. I have had cars with Manuals that did not have these two safety features and never had a problem so, opted to not hook them up. I really didnt want to go hacking into the wring to do it but, the Cruise Control is not working at all so it looks like I dont have a choice and will have to hook it up at some point.*Seen here is the new clutch pedal and cut down brake pedal. Shifter: Well, if you havent figured it out yet you have to cut a hole in the floor for the shifter to come up through. This is pretty self explanatory, measure 1. HAHA I made the hole just big enough to fit the Shift Tower but, big enough to allow for side to side movement when the drive line twists under heavy acceleration/deceleration.
I did this to keep road noise to a minimum; the hole that GM makes is huge and way oversized. The GM Shifter Boot is over $1. I made my own Boot using a Hurst Rubber Under Boot for sound control, a universal Leather Boot and some Diamond Plate I think it came out pretty nice for only $3. My used ZF6 was missing the Gear Selector Lever (the part that sticks out the top of the transmission) because it was lost during shipping, GM was back ordered and I couldnt wait for them.
