How-To - Upgrade Traxxas 2WD Transmission 

This video is for a transmission upgrade. These gentleman take their time to show any & all some things that may help. If you don’t like their approach to the upgrade, if you don’t like their physical aspects, if you don’t like their anything...MAKE YOUR OWN PERFECT VIDEO AND SHOW THE WORLD JUST HOW GREAT YOU ARE!!!!! Thank you Roger & Adam for your time, knowledge sharing & suggestions/advice. Please ignore the the negative & off the topic comments. 🤘🏻

Roger, Adam, thank you. I've been lookin for a good video on how to maintain the diff on my slash for a WEEK. This is by far the best I've seen with in depth details shown instead of cut out. If y'all happen to see this please let me know if you've any maintenance vids on the 4x4 vxl Slash specifically, as I have both the 2wd and 4x4 and the 4x4 is certainly a bit more intimidating!

I'm so glad you did this video. it's everything I wanted to do to my slash before I knew what I wanted to do to my slash. Awesome sauce!

Good call on the top gear/pin. I've had the same problem with my gear stripping and breaking that pin. I saved this video on my favorites. Thanks, for the part numbers. :)

Thank you for all of the time y’all put into this to make quality videos that are easy to learn from keep up the good work👍🏼

glad this showed up in my feed today. just converted my hopped up rustler to slash lcg chassis and lowered it for street bashing and maybe drags if I go to a sealed diff. this will be my next major upgrade for sure once I really want to get serious about a drag racing build.

Thanks for the video, just got a Big Foot July 2019. This is interesting, I do not bash my truck. Really like the information for the future. Thanks and makes things less intimidating. Just got into this RC truck thing at 75 and doing just a few things at a time.

Thanks for taking the time to make this video. I just purchased an entire bearing kit for my rustler. I did the tires this yesterday. I have yet to do the transmission bearings. This was extremely helpful. I may also just go ahead & replace the diff with the sealed version while I'm at it, don't want to have to open it again lol. This ia the part of my traxxas that scares me a tad 😄 I'm ok playing with the pinion & spur, that's cake..... But those loads of tiny pins inside that box, well.... I call that box 'Pandora' 😂

I should admit its so fun to read comments section, thanks for support and feedback everybody!

im new to rc and i am learning a TON from you guys !!! thanks alot!!!

I'm new to this hobby and love it, your videos are the best for people like me...

Nice and smooth, spins transmission crunchy sound.

I’ve had my Traxxas rustler for 2 years and just yesterday I replaced the motor! And the tires I did last month, they were bald and starting to rip through. It runs amazing now! I have a castle creations sidewinder 4 with a 4600kv motor in it

HEY MAN, BIG THANKYOU FOR THE VIDEO! I JUST REBUILT EVERYTHING BUT THE X-MISSION. NOW I CAN TACKLE THAT TOO!

Love the videos guys . Awesome job helping us out to learn all this stuff

A hobby knife for a hobby store would be good ;) Thanks for the how to with part numbers !

I did Hot-racing sealed diff with Robinson idler with RPM case. No problem. Works great. One huge benefit of RPM case is the thick aluminum engine plate vs relying on plastic case. Especially if running lots of power. I also used the Robinson slipper. Seems to be bulletproof so far...

Greeting my friend from Houston Texas ! I’m doing this to my 3s bandit

These videos are so good that I already know how to do this stuff and watched them before but I still find them interesting

Awesome video guys very informative and easy to follow!

The input shaft pin loves it when you land a big jump at full taps on 3s 😇

THANK YOU FOR SHOWING ME MY SLASH IS MESSED UP AND I NEEDED THIS!!!!!

I snapped a top pin and used a small Allen wrench shaft for a pin and it's doing awesome now

DEFINITE NEW SUBSCRIBER HERE!!! I bought a Rustler VXL & Bandit XL-5 in 2018. My son & I drove both of them maybe 1 month(too much power for his age). Been in storage since! Last month, I found em, pulled em both out, and me being a COMPLETE NOVICE, I took both apart as much as I could and detailed/cleaned them up! After 2nd battery run, the Rustler snapped the pin on the top shaft. Having zero knowledge about RC's I took to local hobby shop & watched them fix it for me. Had I found this video/channel a week ago...I'm sure I could have done it! Great camera visual & explanation here! I'll be stopping back by for more How To's... Thanks guys😎💪

Really appreciate the video! My son & I are going to tackle this project together!

I really appreciate the videos you guys make. They've helped me SO MUCH! I don't like the few rude comments, but hey, haters gotta hate. Again, thanks for taking the time to make these videos.

Thank you for this will definitely help I've just put a rocket 4300kv motor in my slash and I'm sure I'm gunna need to upgrade this stuff soon since I killed my original clutch after running down only one battery lol

Sick vid thanks. Nice and thorough.

This video helped me a ton thanks guys.

Just subbed I’m gonna be coming to your channel for everything for my RC car now nice video man.

i have a traxxas rustler this upgrade i will need for future and thanks for for the help and honest opinion

Love the video learned a lot. Thanks for an awesome video.

thanks guys for the help

I just subscribed, I feel that yall will help me out with my other issues. I am so thankful for this video and look forward to working on my rustler this week!!!!

Thank you guys!

Cheers for sharing your knowledge. I've found with my rustler vxl 3s, it always melts casing's where drive shafts are. Have been through 5 lots and getting to be a joke.

awesome vid! keep em coming! ive got the rc fever again

Good tips, the are very useful.

Thanks guys you were a huge help

Sweet man I needed this video for my rustler lol

bro u just saved my traxxas slash from being permanently disabled from having a shot gearbox. I love you

This is just experience from working on systems with bearing on F16 jets but using the shaft to install bearings works well and doesn't require impact tools or a press to force a bearing's installation potentially damaging it. It will just slip in place.

thanks !! i needed this

Good vid thx for sharing guys, i appreciated👍

Hey guys. Love this vid. Very thorough. You mention the 1 flaw in the traxxas case is the built in a-arm mounts. I agree this is a fault, although the rpm 3 piece with 4 small nuts is tought to tighten without removing a bunch of stuff. I feel the main fault of the traxxas is actually the fact that it has to be sealed with a piece of tape. Whats up with that? Look forward to watching more videos of yours. I was surprised how clean the bearings you removed are for a rustler that was driven hard. Mine always seems to get gross. I have to change the bearings everytime i do anything. I buy them by the 100 lot. Be excellent to each other.

I bought (FLM) FastLane Machine's Aluminum Transmission Case and (FLM) FastLane Machine's Aluminum Differential and have been running both for 3 years without a problem. I added a Castle Creations' 1406 Sidewinder 3 4600Kv Motor/ESC Combo. Set the gearing at 21T Pinion gear and 76T Spur gear. Using a 3-Cell LiPO, this set-up drives my 2WD Slash at 50MPH on 2.8 inch JConcepts Rulux Wheels with JConcepts G-Loc Tires (G-Locs aren't supposed to balloon - My set-up proves that wrong, they do balloon!) (NOTE: The motor will need a motor heat sink for 85+ degree day )

Just bought a bandit and already I need this up grade. I just smoked my transmission. Thanks for the deatiled vid for a newbie like me.

Great video 🎉

I loved the proline 2wd trans... I ran mine for 3 years before sheering off the diff output. I bought diff outputs and fixed it but now I see their discontinued so eventually I will have to do this. Its sad because the arm holders are separate and cheap on the proline and so were internal parts so I could just buy arm holders instead of doing the whole trans thing over and over. And it makes 1/3 of the noise.. plus you can tell a speed and power difference instantly, along with the pulling to one side it had b4 being gone. I with there was more options.

I love the camera guys play by play comments after the main guys every sentence!

Thanks you just got yourself a new sub...

Thinking about doing this. I have an rpm case though. I just destroyed all the gears. The differential got some broken teeth into it and messed it up and the intermediate has under 10 teeth as well as the other. I guess that’s what happens with a small spur and 3s lipo when it goes in 2 wheels and your slipper isn’t properly adjusted. Gonna be a fun experience lmao

Great video!

Explanation of what goes where especially those little washers.

nice video

I finally picked up one of these sealed diffs. I'm not sure what silicone grease weight to use. I am seeing info all over the place when it comes to what weight to use. I'm using my rustler for dual purpose, light bashing outside around the house & also for speed runs. Also, does cold outdoor temps affect the viscosity of the grease? Is that 500k cst oil that you used in this video? Thanks, Awesome video!

Amazing mouth breather asmr!

I just put wheel axle ball bearings on 1 yr old Rustler (60 2s lipo runs on dirt&grass) to replace the 8 bronze bushings. Steering was sloppy, now it's great! But when I was setting motor pinion mesh, I noticed a bit of radial play in the top shaft that the spur and slipper run on. Is that shaft that the slipper clutch is on in bearings or bushings from factory? I have 2 more 5x11x4 ballbearings, but I hate to break into the xmission mid season if this play is normal.

My traxxas raptor transmission came with no cut out to move the gear so I can’t upgrade it to a larger one & I was thinking of doing this myself. After seeing this video I’m I said eff that gonna take it to my nearest hobby shop lol thanks for the video guys

The upgrade ideas are great and it's nice to have the option of getting/having those upgrades but you building the diff seemed sloopy. 500K diff oil is the thickest of the thick, put some in and let it settle. Lube the orings and check for proper seating too. I subscribed. GG.

Man i really wish you had a hobby shop and worked there where i live

*This stuff is like peanut butter* Hahaha. Great video guys!

When I need a new pin I cut an Allen wrench to fit and it is strong it doesn't need to be round it's the best way to repair.

As a cheaper option, would you guys recommend a differential locker instead of the sealed diff? (I've also seen people glue their diff to lock it) Do you think it would affect the drivability/reliability?

Hi guys, great video. can you list all the parts you use in this video. this way it's easier to get in my local hobby shop

I need this in my Slash and my Rustler (M.E.G.A.S.).. I bet I could actually do this to the stock unit to better seal it..

9:28 not just that but when these vehicles take a hit, it's usually the weaker parts that break first and those are usually the cheapest to replace. Chose wisely which parts you want to upgrade.

Very new to rc... and there are 3 of us who bought our rigs at the same time and are learning all together... your videos are an excellent tool for us... thank you ... in the description you only out 2 part numbers... nothing for the grease or any other parts you used... could we get all the part numbers

I use an Ultrasonic cleaner and toothbrush if needed to clean parts. It works on small engine carburetors, why not an RC Trans. One thing I am learning quickly is there are no shortage of upgrades for any RC vehicle as long as you are willing to spend dollars.

Are we able to do this to the nitro versions of the slash?

Does this change the sound of the car! I love the sound of my rustler, sounds like a supercharger. Thanks for the video.

After you closed the tran case. Do you put more grease in the hole at the bottom?

Thanks you I just broke my transmission running vxl setup 2c lipo I hit the break at top speed 1 To many times

Hey Guys. I want you to know that I I was gifted in 1992 and afterwards. It's actually quite a long story and I would like to send this to you to let you know I had come across your videos fixing tires on a Traxxas a vehicle with another video showing how to put the gear on to the motor and don't let it slip too much because it would overheat. I have learned quite a bit from the man with the red hair. About my gift? I've never met either one of you men but it's not too hard or difficult for me to pick up that the man with red hair is very knowledgable in these vehicles. No questions asked. I have an Emacs brushless truck and I have light pole three batteries running it. The plastic gears I have burnt most likely in around 20 of them because I am learning on my own and now that I know how to subscribe which I have subscribed to your channel and I know how to get to your videos, I would like to know if there's a way that I am supposed to tighten my tires on the back of my truck from wiggle in a little bit.? I have Botton many many many and too many parts from Traxxas. I would like to know if you tricks or tips as you will call them. I hope you can respond to me soon I'm going to be looking for more videos to come from you and ur little friend u have there. Thanks for your time and have a blessed day. Jason.

Will these parts fit a nitro 2wd rustler transmission? I know the housing looks different but wasn’t sure if gears inside are same?

I appreciate the info with the upgraded parts and even the cleaner. A few things though...I notice no blue loctite when screwing metal to metal. Also, I did not see any grease inside the gearbox, only inside the hot-racing diff??? Lastly, I did not find carbon fiber pads for the rustler from hot-racing. Are you using a version meant for a different vehicle? thanks!

what w as the name and brand of the slipper clutch and will it work on a Traxxas slayer?

Nice👍

That differential part of video was hard to see fast forwarded like that. Ill figure it out. I always take pictures of everything before I take apart

I have an Robinson Racing idle gear entegy transmission and stock gears... I like the aluminum transmission.. it's just heavy but I'll keep my stock case just in case

How much grease should be used and what is a good brand?

Ive had my slash for a year and ive only had to replace the rear skid plate just did that on sunday

Great video guys, I just subscribed to your channel. I 've done this exact upgrade/rebuild for my 2wd but my mamba monster still chewed some teeth off top gear. Will the Associated top gear you mentioned in video work as a replacement part for the Slash 2wd? If so which one? Thanks in advance for your help.

Will the Hot Racing hardened steel idler gear work in a RPM hybrid gearbox when also using the Hot Racing sealed planetary differential or would I still need to stick with the stock Traxxas VXL steel idler gear? As I have a rustler Vxl 2wd with the RPM hybrid gearbox (I got the truck used for free and it has other mods.. RPM carriers on all corners, aluminum shock caps on stock shocks, aluminum rear shock tower, STRC front brace, RPM front bulkhead, stock tires and wheels, stock gearing, duct tape reinforced body, updated suspension pins, and RPM caster blocks…

For more take off speed doese the pinion gear have to have more teath or smaller or both

great video guys how are you guys doing over there in long beach CA? i hear its beautiful. be safe guys

Traxxas 272R Magnum idler shaft is 1 piece and fits the standard 272 transmission.

Like your video guys. Just wondering, it looked like there was no lube put on the gears when you reassembled, but metal on metal would seems to want some form of lube, especially if the diff grease is staying inside the diff.

Hey guys, thanks for the video, I saw James J question below, but I didn't see why you don't lube the sealed diff, idler, and top shaft gear teeth, do you put them in dry, or some sort of lube ?

Can I like meet you in person and come to the shop ! Looks awesome and you have so much knowledge I’d love to learn ! I’m from central Nj

So even though my nitro slash has a different spur gear the transmission is still just like this one?

Will this also work for the Nitro Slash 2wd ?

can i get a list of parts used thinking of using this upgrade on my rustler and stampede 2 wheel

Do I have to do this if I get a velineon system?

What diff oil is good for a slash 2wd for normal running and racing on dirt

qhere can i get the sealed differential

I think Traxxas may have put thicker grease in the newer 2WD transmissions. My Bandit, Slash and Rustler (all three are just under a year old) all seem to have very smooth yet somewhat stiff diff action like my Rustler 4x4 and Slash 4x4 VXL's.

Nice tutorial!. What kind of grease can i use on the transmission? is there any generic/easy to find grease suitable for the purpose? Greetings from Argentina

I had to upgrade from the plastic driveshafts after snapped them in half, also the Bandit trans will also work in them

If you put blue loctite on the idler shaft where the gear sits I have found it prolongs shaft life.
