Traxxas Transmission 272 and Magnum 272R Pro Series and Pro Line 32P ProSeries Component Comparison

I compare all features of the three transmission (Traxxas standard 272, Traxxas 272R Magnum Pro Series, and Pro-Line 32P Pro Series). The compare the gearbox, slipper system, and take them apart to look at the internals. I also go over the maximum size pinion gear with a 76T (Traxxas models) and 56T (Pro-Line models).

I have the Proline, But I really want the magnum 272 because how hard I bash, I keep splitting\cracking trans case on the Proline & the ease of filling the diffs in the magnum is much easier, really wish I did my home work, I bought it the week they released it & literally just seen the clear gear cover & had to have it haha

[@telecomandorc]

It doesn't fit. If you do not mind not using the dust cover, you can use a Revo gear.

Great job. This really saves us a lot of time and money. It's a bummer when you buy something thinking it might fit only to find out it doesn't. Totally enjoyed learning about these transmissions. 👍👍

i like the look of the proline but i like the magnum functionality more lol, and im thinking you could perform just as good as these with the stock housing, they make a Hot racing sealed diff that fits in the stock case, and buy the slipper shaft with no roll pins

[@telecomandorc]

I like the layshaft swap. The only thing is the 272R does have the kick-up built in. I had the HRATE38CH but the large thin o-rings leaked. Good thing for Harbor Freight and their o-ring sets.

[@ConditionZero76]

you mentioned using a 40 tooth pinion w/ the 76 t spur, are you running that with stock vxl motor & esc on 2s for drag racing? if so have you had any issues, I have 76 - 31 I assumed going any higher might be bad but now you have me thinking?? Thanks

[@telecomandorc]

I am not running that set up at this time. I did it to give people an idea. A 35-36T is better because it is smooth (easier to modulate throttle with stock esc) but runs cooler for more passes. It depends on how many consecutive passes you will do. But I do have a 76T spur. A 48P will be fine with a stock VXL on 2s. If you run a more powerful system you may want to consider a 32P... with MOD1 you lose tuning capability.

You could, but I would not. A Castle 1515, for example, is heavy and way too much torque but not enough Kv. The think will flip over if you sneeze. The Tekin ProHD 4300Kv is a great 2s motor. The Tekin T8i is an amazing motor up to 4s. But even 4s I find is too much.

[@RickyRacer59]

I would love to see you include the RPM transmission. Nice video!

[@telecomandorc]

The RPM transmission or hybrid gearbox has too much flex. That is really why I did not include it. It is not something I would really consider anymore. The proline is nicer and works great in a Slash with a 16T pinion with a HW 3660 system. Or a Tekin ProHD.

[@danielvance2371]

Got the proline transmission and added the velinion 3s at same time on 2wd rustler. Put the traxxas wheelie bar on and that in my opinion was the problem. The proline is awesome but the 1st 2 or 3 wheelies put to much stress on rear case of trans and broke the case around the rear. Just installed the magnum 272r and it seems beefier in that rear section. Will be testing. Other notes on proline is the largest pinion that can fit is 19t honestly I think it's fine because it comes with 56 tooth spur

[@telecomandorc]

I never thought about it. I wonder if the PL would handle the wheelie with the damper in it. But the 272R is a very good transmission. Glad you picked one up.

[@kylebeach2316]

Would you recommend the upgrade from the 272 too the 272r? I do bash/jump my slash alot and I also have it setup too run 3s with the vxl system.

I love how they're already 139.99 lol what's better on a 2wd slash the 242r or the proline? I bash around on grass dirt and asphalt and like go make it do wheelies lol I've blown up 2 Traxxas transmissions

[@telecomandorc]

That is a tough one. It depends on your set up. I prefer how the motor mounts on the 272R. I also like the slipper with HR long Al pads as they are stronger and more aggressive for 3s use. The PL slipper system is not very good for 3s... great and smooth for 2s... not so much 3s. If you have the PL, I would stick with it. If you have neither, I would go with the 272R. It is more tunable as far as clutches and FDR since the motor can mount farther.

[@jefflesser630]

What’s the best pinion/spur combo for that 272 magnum with the vxl3s motor? I’m after top speed? Not sure what that motor can handle, just got it and about to get the transmission.

[@telecomandorc]

It should have included a 28T pinion assuming it has an 86T spur. But it will probably lift due to the body before it gets to top speed. You will have to cut out a large window in the rear of the body. It you get a 76T spur you can do a 26TT pinion. The 28T pinion with a 76T spur takes too long to get to top speed, and is too much heat. Keep in mind you will only be able to do a few passes and will have to let it cool as the motor will overheat.

[@jefflesser630]

Thank you. I do have the 28t on currently and can not go full throttle with out it lifting. I will cut a whole in the body and give it a shot. Thanks again.

If cost is not an issue, I would get the 272R. I like the way the Slash handles dirt with the kick up built in. I can hold a little more power. The 272 is easier coming off power, but not by much... and only in abrupt negative acceleration changes... So 272R is my pick. You can always get the top shaft for about $8 and the HR sealed diff for close to $50. But the HR diff I have leaked due to the o-ring seals shrinking. So I have to replace those.

It can handle a 35T pinion. If you are just doing speed runs and stopping to cool in between, it will be fine. But, as you already know, the thing loved to flip over on hard acceleration. So plan on a long straight. You have a different Tx, right? The stock does not have much range.
