- What all it takes to swap an automatic transmission over to a manual transmission in a 1973-1987 GM truck, k5, suburban.
Got questions or need more vids? just ask.
Truck in vid is a 1977 K10
Originally had a th350 and np203
Now has a sm465 and np205
Thanks for watching
Aluminum Automatics & 203’s suck in 4x4’s.
The 465/205 is the best way to go.
Excellent work brother!
Great Video young man,someone somewhere have invested time and knowledge in your life, great job .3thumbsup
I appreciate that! I am self taught but did have some great help along the way and very supportive parents. Thanks for watching!
Thanks for the video. On the Neutral switch you can push in the tabs and lift up the plastic switch up from the column. Tape around the switch itself on both sides of the yellow selector so it can not move then zip tie it up out of the way. No more issues with the thing not starting.
Thanks man- I already have all the stuff for the conversion, pedal assembly, hydro clutch/bellhousing, tranny etc. I parted out an 88 V3500 a few years ago that had rolled and the stuff has been sitting in my shop for 3 years. Already rebuilt and swapped in the 454 out of it into my FrankenK5. I never thought the TH350 would last as long as it has behind a big block. It is still doing fine, but I want to go ahead and put the 465/205 in this winter along with the D60.
Thanks for the overview starting this swap on mine tomorrow tired of waiting 700r4s never had one make 30k behind my lazy stock 6.5na
ITs awesome swap. I do have an OD to put infront of it. I would love to try that tremic 4050 to be honest
Dude, you just saved me a TON of trouble!
i like how you did that i am trying to swap out an auto to manual my self and you made it look easy thanks if i have any questions i will talk to you, if i need to, i believe you would help me out with that thanks.
First I went from Np203 to an Np205 when I was still using the th350 auto. When I switched the transfer cases I had to get the drive shaft leangthened because the np205 is shorter then the np203. Both units had fixed rear yoke set ups. When I put in the sm465 Everything bolted up. So an sm465/np205 and a th350/np205 are roughly the same leangth.
Pretty informative video. Nice looking K10 and C10 you have there. I'll probably be doing a 465/205 swap over the winter in my K5.
The bell housing bolt patern is the same from SBC - 454 and the 6.2 and 6.5 diesels. . What you want to swap out is the gear indicator in the dash... Very easy job. The SM465 already has reverse wiring on the shift tower cover on the transmission. You have two options... Steering colum out of an auto truck or run a floor mounted automatic shifter. Also your neutral saftey switch will need to be redone. Its very easy to do and all bolt on and alittle wiring.
Great job Ian. Thank you so much.
I bought a 1984 K1500 that had the auto to manual swap done. It had a sm465 but I sold that and proceeded to LS 5.3L and nv4500 swap. Great video - I have had questions on the backup switch on the steering column and how to stop the old shifter from moving from its park configuration. thanks for the video
thanks. Tried to keep it as factory as possible for ease of repair. Can't wait to get the diesel swapped in.
1985 and up uses hydraulic clutch and parts are more expensive than the z-bar clutch. I'm using z-bar on my 1984 C30 swap to manual. Already got the high hump transmission pan.
right and Z bar is much more reliable. The down fall to a Z bar is flexing it offroad and the heavier clutch pedal. I used the hydro set up as it was an easier install and I had wheeled with people whose Z bars came apart on the trial and I did not want to deal. IT a stout simple setup that works! both are good.
Good job man! I was thinking of doing this in a Crown Vic. I hate automatics and will not drive them. Boring...
Me too,I'm 65yrs.and my first auto was a straight shift, 65 chevy Malibu 3 on a tree and have been in Luvvv with stickshifts every since 😆 for me its just Nothing like it! 👍
id leave the column as is kinda like a secret security anti start from anyone else turning it over. who would know?? XD
I picked up an 84 K25 burb that I was wanting to do a drivetrain swap for. I've got a TH-350 in mine…wanting a NV-4500. Swapping the engine too (main reason for wanting the NV-4500).
will swap in easy as hell.
You could have saved yourself a lot of work if you just got a hydraulic clutch pedal and master cylinder from Jegs or Summit. Drill three holes and you're done.
True but I like having the factory parts. Plus it was cheaper for me this way as i bought a used setup from a K5
yeah it is pretty easy. The steering colum wirieng will be diffrent since they did not have cruise on the coolum in 77 but did in 87. Also in 77 the wipers are in the dash but in 87 they are on the colum. you will need to swap pedal boxes and add floor hole for the clutch Z bar set up unless you go hydro clutch like what came in 85 and up.
Manual, or Manuel. Manuel sells the parts.
All front 10 bolts are the same. The only diffrance is that some have 28 spline axle shafts and others are 30 spline (1988 and up). The way GM made them "3/4" ton was to change out the hubs,rotors to make them 8 lug. The rear there is a few options. Half tons have a 10 bolt or a 12 bolt. 3/4 tons have a semi float 14bolt 9.5 ring gear or a 14 FF 10.5 ring gear axle which is the same as the 1 ton except the spring perch spacing. 1 tons had 14FF or Dana 70 rears and Dana 60 froints.
Nice truck
I have the exact same color and look of that 87
@chevyking10 yes the 700r4 will fit. It came factory behind the 305 in many trucks
Trying to do a 5 speed swap from the junkyard on a 1973 chevy pickup.350 .its already manual 3 speed. ..what yrs/models do I look for ...do I need the pedals too? Any help would be appreciate
Depending how you use the truck will change your transmission choice. The 200r4 is a cat trans and not beefy enough for your truck. If you want to stay manual a NV3500 or a T5 would give you an easier hydro clutch , overdrive, a and a car like closer ratio shift..
Ian
Do a mechanical z-bar linkage, a lot easier, and fewer parts.
no infact it is easier since you don't need to mess with the pedals. You will need to swap colums or run a floor mounted shifter.
Will the manual clutch pedal assembly work on my hydraulic set up only question I have. Mines already been swapped from 700r4 to sm465-np205 with a slip yoke.
Certainly... actauly it should fit any chevy c/k engine like 263, 305, 350, 400. The bell housings are almost all the same on the trucks even the diesels... Your looking at a lot of work because you need a steering coulum for the shift linkage and you need to wire your back up lights
Engaging rod hole for manual clutch where would it be must I cut it .and how would I locate it.
If u can find one u can change out the transmission hump to a manual....saves cutting the floor out
+KC Newton You dont even have to, all you have to do is cut another hole for the transfercase shifter.
Great video! I have a 85 K20; 350, 4wd, what’s the secret to bleeding the clutch slave cylinder? I went thru all the motions with a jar with brake fluid in it with hose attached, etc. .i can’t get enough pedal to release the clutch. Won’t go into gear with motor running. Just thought you might know thanks!
Good video man
I have a question I have 1982 Chevy c10 I want to put a manual transmission do u know what year can be the same ?
Good video
Thanks! Thank you for watching
nice work
I'd like more info on swapping an automatic to an nv3500
I have not done that swap in a square body. I am sure the pedal swap would be the same. you would need to adapt to the NV hydrolics and spline count on the transfer case might be an issue. Also I would think the nv3500 is longer then an sm465. Thanks for watching!!
coolo. If you have any questions feel free to ask.
Go with the 700r4 it has an overdrive so it will give you the best gas mileage. My c10 and k10 have that tranny
I took my dads 73 chevy pickup 350 short bed out for a night and I toasted his 3 speed manual tranny. ..just my luck ..so I have to replace it. ..wanted to do a 5 speed swap.. and was wondering what cars I should be looking for at the wrecking yard for tranny, hydraulic setup/clutch? ect. .any help would be appreciated. .thanks
ally chevy truck engines have the same bell housing 262v6 to 454 bb and even the duramax has the same bell housing.... ;;;;; only the new vortec motors.. 4.8 5.3 6.0 they will bolt up to chevy trans bell they just have a additional bolt to spread out stress
I have a '92 Chev S10 (last of the 80's style) auto trans. I want to convert to electric but I'm told it's better to have a man trans. What would I need to buy (part numbers?) to do this?? Any help extremely appreciated. This belonged to my grandfather and I'm trying not to junk it, so it's for a good cause.
Having an issue with my swap!
79 Cheyenne automatic 350 pulled to fit 86 Chevy k10. I pulled the k10 engine 305 and I'm swapping it with the 79 350 automatic.
Issue: when I'm putting the 350 into the transmission everything is smooth sailing except for about an inch where the transmission won't fit right into the engine! Do I have to pull out that pilot bearing from the 350 engine first? Using basic wrench tools, no garage and fighting weather! Any help or advice would be appreciated...also the truck is on my page if anyone needs to see it.
great Video, I have an 1986 gmc c15, I'm planing on swapping out the automatic to a standard I was just wondering how long it took to switch everthing over? thanks Shawn
I have a 78 c10 that has the TH350 and I’m looking to swap to a manual. Its got a pretty hot small block in it. What would be the strongest/easiest 5 speed to put in it. Possibly a T5 out of a camaro?
T5 would be good or maybe a nv3500. But the t5 will shift more like a car which is what you want in a 2wd with a hot small block
If anyone wants to convert from manual to auto I will trade them. I have a '74 K5 4x4 w/ SBC 350/TH350 and np203. Will trade flexplate, torque convertor, transmission, shift linkage and column, transfer case for your flywheel, clutch, bellhousing, clutch linkage, shift linkage, and transfer. Car is in southern California and I have done trans conversions before.
What headers are on there? Mine block the hard lines to the slave cylinder need to change them out for clearance
Stock manifolds.
Great video's. Just finished sm465/205 combo how did you bleed the hydraulic lines Thanks
thanks fer the video
What kind of transmission did that bell housing come from that you used to connect your NV4500? What year bell housing did you use? Also what SIZE clutch and flywheel are you using in that bell housing?
how does throwout bearing clearance work here ?im tryimg to do the same basicly but is there any return spring on the fork so it keeps the bearing off the pressure plate when clutch is released?
What lift and what size and brand tires are you running? Looks like a nice size truck and still practical.
How did you do the pedal assembly?
Can you get some pictures of the master cylinder and how it mounted. I'm to the point of drilling for it and don't want to screw it up. Thanks!
I made a template off a 86 firewall in the junkyard. if your truck is 86 and up your firewall should be stamped for the hole
Did you use your np203 driveshaft yoke for the 205 or were they different?
Alright I have a problem, I have the same front axle as your 88, however, I also have the GM Corporate Big 14 Bolt Axle pushing my High Sierra Jimmy. The Problem I am having is if both axles are 1/2 or 3/4 ton
oka so just bought a 87 350tbi reg cab long box 2wd with an auto now got same truck sept 77 with 350 and 4spd manual would it be fairly easy to swap im thinkin about Putin both trucks side by side I dont think it should be s huge job
thanks but do you think the 700r4 will fit with a 305 engine
Good video. I'm about to undergo swapping out my 400/203 for a 465/205, I can't find anything for hydraulic clutch set ups in my local yards at the moment. So I''m thinking about going with a manual clutch, which I've got experience with. My truck is a 79 K25 lwb, would I need a one piece or two piece drive shaft? Would prefer to possibly keep my slip yoke. Could I also reuse my front driveshaft? Thanks in advance.
for the Front Drive shaft you most likely would need to change that out 50/50 to relocating the cross-member mount from Automatic to Manual Tranz "long to Short Body" as for the rear axle is your choice give or take of the Tcase tail hosing for the yoke but you still might have to rebuild that to compensate the length said and viewed like this part of the film for example 6:30 to 8:40 hope this helps straight and simple dose not really matter of year body style truck if you plan to lift your truck with swapping the trans either or
you said in your video your rear drive shaft was to short after you did the swap??
do to the th350np203 being longer than the 4 speed
reading some of the comments i noticed that for the most part everyone rather have a manual transmission, i on the other hand have a 79 chevy camper special that i use to haul a tow dolly and because i drive a lit on the city i find manual transmission anoying having to shift a lot, what is the interest for a manual convertion? can someone explain
I mostly like them better, because I have a lot more control over what the vehicle does. When i want to be in a certain gear,I don't like the transmission changing it for me.
a manual has a lower 1st gear, 7:1 in case of gm, great for towing and rock crawling...
can you redo the video with better light under the dash I can't see anything.
1980 chevy c10
any one have any suggestions on another good trans? I feel like the sm465 won't be quick enough and they are placed too far apart. And maybe even a five speed would be better?
What power you making 2 or 4x4? For better shifts NV3500. For streangth NV4500
Ian I have a 76 c20 with a 454. it's only rear wheel so I'm keeping it as a street vehicle. so nv3500?
How much did you lengthen the driveshafts?
Is it possible to change a 94 suburban with a 6.5 turbo diesel automatic transmission
into a manual transmission?
absolutely but a 94 will need a more creative clutch pedal or the dash taken apart
What car or truck did the doner trans come from
Came out of a friends offroad K5 blazer. Originally the trans used in this vid came from a 1980 chevy K30. IT later got replaced with a Trans from a 1975 K30. These transmissions were used in GM's from the 60-early 90's. The bellhousing was from a 1986 K10 and the pedal assembly was out of a 1987 R30 (K30)
what do you do with the plugs and stuff connected to the automatic when you convert to the manual?
Depends on the vehicle. Most early computer controlled transmissions have a stand alone computer (I believe). So that can just be removed, along with the wiring. But don't take my word for it, talk to a mechanic..
Would it be hard going convert frm manuel to auto
ok i have a chevy 350 dump truck with 4 speed trans i was trying to put a 350 turbo automatic trans is it possible
nathan lofties yeah it is,
i recommend a th400, stronger
I have a 1978 GMC sierra full-size, 454 engine. how much do you think it will cost me to convert it to manual transmission?
Suli MetalHead 2500
+Suli MetalHead What trans are you using? are you doing the work???
if you put the subtitles on, this is the funniest shit! haha
I have a 2013 Chevy suburban truck how much do you think I will cost to change to manual??
Curtis Blackburn not possable sadly
Im sorry to but anything is possible. not saying its gonna be remotely easy but can be done, and im not saying it will be street legal when its done either, and would most likely require an entirely different or new drive-train,and a shitton of fabrication but it can be done
Ballpark cuz im in the middle of swapping one 91 SQB Burb.....2500.00 give or take how and were you obtain these parts and what kind of clutch kit and trans you need
Did you have to do any welding?
No welding for this swap. All bolt in and drilling the hole for the clutch master cylinder and the hole in the floor for the shifter. Thanks for watching. Let me know if you have any questions.
@@84400 Cool, thanks for the reply 🙌 my next project is taking out the 700r4 from my 83 Suburban and putting in an SM465 from a 71 Jimmy. I have the tranny and the pedal assembly sitting in my garage already, so I'm gonna go for it
proton perdana auto change manual evo gearbox
i have a 1989 jimmy 350 could i convert it to manual.
Yes. They made them.
what kind of car do you have?
ha
Great Video man. Helped a lot. I am putting same tranny/transfercase in my 88 gmc burb. My transfer case is fixed yoke.
