Transmission durability?

[HawnMT]

I am thinking about going to 35T lathe motor that puts out over double the torque of an Integy 65T lathe. I am worried about the durability of the highlift trans standing up to the power and speed of this motor. Anyone have any advice about whether or not this is feasible? I don't want to buy a motor that will tear apart the tranny.

Since the transmission does not appear to have problems coping with the Novak Brushless Crawler System there should not be a problem for you. However, I see no practical need for that much power.

Are you planning to get extremely big tires for you truck? I ask since the stock motor never runs out of power with the stock tires. Power is never the problem,although grip sometimes is.

Getting a bit more power for 2.2" wheels is one thing but getting too much more power will not add to driveability.

The setup will be for 2.2 mudslingers on aluminum beadlocks. I was hoping for a little more power but this motor option just became available. Since the motor hasn't been released yet (still in preoder, should be go out this week), I'm still waiting for some feedback on it.

I think that the problem is not the gear box itself, is very hard and working in low speed will be able to receive all the torque from the motor. My concern is about the precise time when you make the gear shifting, if you do that under the power of the motor meanwhile pushing big wheels or a hard off road way, then something could be broken.

The old 3 speed gear box had a weak part, the spur gear, if you made a bad gearshift servo setup, or changed the gear in motion, then the spur gear could be broken, because was the only nylon piece. The new one is homogeneous and had not the spur gear problem, however under a lot of torque nobody knows what could happen.

I run 75T, and I shift under speed.
No problem!
I even run the engine in high speed, and then kick it in gear.
There's no problem at all.
